Definitions

  • the present invention relates to use of an alkylether sulfate of the formula (I) as defined hereinafter for improving the herbicidal effect of one or more herbicide compounds, and to a method for controlling undesired plants, in which at least one alkylether sulfate of the formula (I) and at least one herbicide compound, as defined hereinafter, are applied to the undesired plant or its habitat.
  • the present invention also relates to an herbicidal formulation comprising at least one alkylether sulfate of the formula (I) and at least one herbicide compound, as defined hereinafter.
  • the present invention relates to an aqueous spray liquor comprising at least one alkylether sulfate of the formula (I) and at least one herbicide compound, as defined hereinafter.
  • herbicides are widely applied in order to control growth of undesirable plants, such as weeds, because the undesired plants compete with crop plants for water, nutrition and sunlight and therefore reduce crop yields and crop quality.
  • Herbicides may be applied to clear cropland from undesirable plants before sowing or planting crop plants. However, depending on the crops and their compatibility with the herbicide, the herbicide may also be applied to fields where the crop plants grow.
  • herbicides In order to be effective, herbicides must overcome a variety of barriers (morphological, biological, and environmental) to their entry into target plants. For example, trichomes on the leaf surface can reduce herbicide efficacy by intercepting spray droplets before they contact the epidermal surface.
  • Environmental stress e.g., hot, dry weather
  • an adjuvant is an ingredient that aids or modifies the action of the principal active ingredient.
  • Adjuvants can be roughly classified into 3 groups: activators, spray modifiers and utility modifiers. Activators will mainly increase the efficacy of the herbicides by various modes of action.
  • Activators are typically surfactants, in particular non-ionic surfactants (NIS), including silicone surfactants, oils, such as high surfactant oils, crop oil concentrates, vegetable oil concentrates and modified vegetable oil concentrates, and wetting agents.
  • NIS non-ionic surfactants
  • Spray modifiers will alter the properties of the aqueous spray liquor and thus facilitate aiming the herbicide spray, reduce herbicide drift in the air or may cause the spray to more readily adhere to the plant by various mechanisms.
  • Utility modifiers help minimize handling and application problems. They widen the conditions when an herbicide can be used or maintain the integrity of the spray solution. For example, utility modifiers reduce foaming, increase solubility, modify pH, or reduce spray drift.
  • herbicide adjuvants In contrast to activators, spray modifiers and utility modifiers usually do not improve the biological efficacy of the pesticide but facilitate the application of the aqueous pesticide spray liquor.

Description

Use of an alkylether sulfate for improving the efficacy of herbicides Description The present invention relates to use of an alkylether sulfate of the formula (I) as defined hereinafter for improving the herbicidal effect of one or more herbicide compounds, and to a method for controlling undesired plants, in which at least one alkylether sulfate of the formula (I) and at least one herbicide compound, as defined hereinafter, are applied to the undesired plant or its habitat. The present invention also relates to an herbicidal formulation comprising at least one alkylether sulfate of the formula (I) and at least one herbicide compound, as defined hereinafter. Moreover, the present invention relates to an aqueous spray liquor comprising at least one alkylether sulfate of the formula (I) and at least one herbicide compound, as defined hereinafter. BACKGROUND ON THE INVENTION In agriculture, herbicides are widely applied in order to control growth of undesirable plants, such as weeds, because the undesired plants compete with crop plants for water, nutrition and sunlight and therefore reduce crop yields and crop quality. Herbicides may be applied to clear cropland from undesirable plants before sowing or planting crop plants. However, depending on the crops and their compatibility with the herbicide, the herbicide may also be applied to fields where the crop plants grow. In order to be effective, herbicides must overcome a variety of barriers (morphological, biological, and environmental) to their entry into target plants. For example, trichomes on the leaf surface can reduce herbicide efficacy by intercepting spray droplets before they contact the epidermal surface. Environmental stress (e.g., hot, dry weather) may develop a thicker than normal wax layer, or increase other defensive structures such as reducing the plant’s metabolic and transport processes that are required for adequate weed control. Consequently, the biological activity of an herbicide may not be satisfactory or at least lower than expected. While higher application rates may achieve better herbicidal efficacy, this is often not possible for regulatory reasons and is not desirable for ecological and economic reasons. Rather, there is great interest in increasing the biological effectiveness, also termed efficacy or biological efficacy, of herbicides in order to reduce application rates in this way. It is well known that the efficacy of herbicides can be increased by certain adjuvants. Adjuvants (from Latin, adiuvare: to aid) are commonly used in agriculture to improve the performance of herbicides or other pesticides, including better mixing and handling, increased effectiveness and safety, better distribution, and drift reduction. Broadly defined, an adjuvant is an ingredient that aids or modifies the action of the principal active ingredient. Adjuvants can be roughly classified into 3 groups: activators, spray modifiers and utility modifiers. Activators will mainly increase the efficacy of the herbicides by various modes of action. Activators are typically surfactants, in particular non-ionic surfactants (NIS), including silicone surfactants, oils, such as high surfactant oils, crop oil concentrates, vegetable oil concentrates and modified vegetable oil concentrates, and wetting agents. Spray modifiers will alter the properties of the aqueous spray liquor and thus facilitate aiming the herbicide spray, reduce herbicide drift in the air or may cause the spray to more readily adhere to the plant by various mechanisms. Utility modifiers help minimize handling and application problems. They widen the conditions when an herbicide can be used or maintain the integrity of the spray solution. For example, utility modifiers reduce foaming, increase solubility, modify pH, or reduce spray drift. In contrast to activators, spray modifiers and utility modifiers usually do not improve the biological efficacy of the pesticide but facilitate the application of the aqueous pesticide spray liquor. A review about adjuvant technology is given by Z. Pacanosky, Herbicide Adjuvants (2015), DOI: 10.5772/60842. A summary of commercially available adjuvants for herbicides, hereinafter herbicide adjuvants, is given by B. G. Young et al. (ed.) “Compendium of Herbicide Adjuvants”, 13th Edition (2016), Purdue Extension and Southern Illinois University (https://mdc.itap.purdue.edu/item.asp?Item_Number=PPP- 115). Water-soluble herbicides, such as glufosinate, are chemical substances that penetrate and damage and/or destroy plant cells, tissues or parasitic organisms in or on the plant. Formulations containing water-soluble herbicides are commonly used in the form of liquid or solid concentrated preparations that facilitate user handling or provide increased effectiveness of the active ingredient. The formulations are typically diluted with water prior to use and then applied by spray application. Water-soluble concentrates (Soluble Liquids, SL) are a particularly important form of herbicide formulations, wherein the active ingredient is often used as a water-soluble salt obtained by neutralizing the acid form of the herbicide with suitable bases. Particularly in the case of water-soluble herbicide compounds, such as glufosinate, the type and quantity of adjuvants used have a decisive influence on the efficacy of the formulation. Aqueous formulations of glufosinate ammonium are known, for example, from EP-A-0048436, EP-A-0336151, EP-A-1093722, WO 2007/147500 A1 or WO 2007/092351 A2, wherein alkyl ether sulfates are used as adjuvants. Up to now, alkyl ether sulfates having a C12-C16 alkyl chain and 1 to 10 alkylene oxide unit(s), such as sodium lauryl ether sulfate (SLES) or sodium myristyl ether sulfate, have been used as adjuvant in commercially available formulations of glufosinate. However, they are associated with certain drawbacks. One of the main drawbacks thereof is their efficacy as adjuvant. Even though they enhance the effectiveness of the active ingredient in the formulations the enhanced effect of the active ingredient is not satisfactory enough. Furthermore, the biological activity of the active ingredient is dependent on the proportion of the active ingredient to such alkyl ether sulfates. Therefore, to achieve a satisfactory adjuvant effect with the conventional alkyl ether sulfates a high amount of such alkyl ether sulfates has to be applied in the formulation. Nevertheless, if the amount of such conventional alkyl ether sulfate is too high, the viscosity of the formulation may become too high for easy handling or spraying. Thus, there is an ongoing need to find adjuvants for formulations containing water-soluble herbicides that may satisfactorily enhance the herbicidal efficacy of the active ingredient in the formulation and at the same time may have no adverse effect on the physicochemical properties of the formulation. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide further compounds which increase the activity of herbicides, in particular, of water-soluble herbicides. Moreover, such compounds should have no adverse effect on the physicochemical properties of the formulation, at best they should lead better foaming behavior for easy handling or spraying of the formulation containing water-soluble herbicides such as glufosinate. Surprisingly, it has now been found that the alkylether sulfates of formula (I) as described herein increase the effectiveness of herbicide compoundsto a greater extent than the above-mentioned alkyl ether sulfates, such as sodium lauryl ether sulfate or sodium myristyl ether sulfate which are frequently used as an adjuvant for herbicides, such as glufosinate. Therefore, the present invention relates to the use of at least one alkylether sulfate of the formula (I) [R-O-(A-O)n-SO3]- M+ (I) in which M+ is a cation; A is C2-C3 alkandiyl, such as CH2CH2, CH2CH(CH3) or a combination thereof; R is branched C10-alkyl, in particular 2-propylheptyl or isodecyl; and n is an integer in the range of 1 to 10, preferably in the range of 1 to 8, in particular in the range of 1 to 7, especially in the range of 1 to 5; for increasing the herbicidal effect of one or more herbicide compounds. The present invention also relates to a method for controlling undesired plants, wherein at least one alkylether sulfate of the formula (I), as defined herein, and at least one herbicide compound are applied to the undesired plants or their habitat. The alkylether sulfates of the formula (I) can be easily incorporated in conventional herbicide formulations of one or more herbicide compounds, in particular into liquid herbicide formulations. Therefore, a further aspect of the present invention is a herbicidal formulation comprising i. at least one alkylether sulfate of the formula (I) as defined herein; and ii. at least one herbicide compound. For controlling undesired plants, the at least one alkylether sulfate of the formula (I), as defined herein, and at least one herbicide compound are usually applied as an aqueous spray liquor. Therefore, the present invention relates to an aqueous spray liquor comprising i. at least one alkylether sulfate of the formula (I) as defined herein; and ii. at least one herbicide compound. The alkylether sulfate of the formula (I) of the present invention has several advantages. First of all, it improves the herbicidal effect of herbicide compounds. In particular, it improves the effectiveness of various herbicide compounds, e. g. glufosinate as well as salts of glufosinate, to a greater extent than other alkyl ether sulfates known as activator adjuvants for herbicides, such as SLES. In particular, it improves the efficacy of the herbicide with regard undesired plants which are difficult to control and thus broadens the applicability of the respective herbicide compound(s). For this, the alkylether sulfate formula (I) can be co-formulated with the herbicide compound in aqueous as well as in a non-aqueous herbicide formulations. It may also be mixed with a conventional formulation of the herbicide compound in an aqueous spray liquor (tank-mix).

Examples of herbicide compounds of the group (a) include but are not limited to bilanaphos (bialaphos), bilanaphos-sodium, glufosinate, glufosinate-P and glufosinate salts, e.g. glufosinate-ammonium. Glufosinate (CAS Reg.

For example, glufosinate and its salts, such as glufosinate ammonium, and its herbicidal activity have been described e.g. by F. Schwerdtle et al. Z. Pflanzenkr. Pflanzenschutz, 1981, Sonderheft IX, pp.431-440. Formulations of glufosinate as its racemate and its salts are commercially available, e.g. under the trade-names BastaTM and LibertyTM. Glufosinate is represented by the following structure (IV): O O H3 C P CH2 CH 2 CH C OH (IV) OH NH2 The compound of formula (IV) is a racemate. Glufosinate is a racemate of two enantiomers, out of which only one shows sufficient herbicidal activity (see e.g. US 4265654 and JP92448/83). Even though various methods to prepare L-glufosinate (and respective salts) are known, the mixtures known in the art do not point at the stereochemistry, meaning that the racemate is present (e.g. WO 2003024221, WO2011104213, WO 2016113334, WO 2009141367).

Antifoam agents which are suitable for the aqueous SCs according to the invention are, for example, silicone emulsions which are known for this purpose (Silikon^ SRE, from Wacker or Rhodorsil^ from Rhodia), long-chain alcohols, fatty acids and their salts, antifoams of the aqueous wax dispersion type, solid antifoams (known as Compounds), organofluorine compounds and mixtures of these. The amount of antifoam agents is typically 0 to 1.5% by weight, based on the total weight of the SCs. Preservatives may also be added to the suspension concentrates according to the invention for the purposes of stabilizing them. Suitable preservatives are those based on isothiazolones, for example Proxel^ from ICI or Acticide^ RS from Thor Chemie or Kathon^ MK from Rohm & Haas. The amount of preservative is typically 0 to 0.5% by weight, based on the total weight of the SCs. Suitable antifreeze agents are liquid polyols, for example ethylene glycol, propylene glycol or glycerol, and also urea. The amount of antifreeze agents is, as a rule, 0 to 20% by weight, in particular 5 to 10% by weight, based on the total weight of the aqueous suspension concentrate. If appropriate, the aqueous SCs according to the invention may comprise buffers to regulate the pH. Examples of buffers are alkali metal salts of weak inorganic or organic acids such as, for example, phosphoric acid, boric acid, acetic acid, propionic acid, citric acid, fumaric acid, tartaric acid, oxalic acid and succinic acid. The inventive herbicidal formulation may also be an oil dispersion (OD). In such oil dispersions, the active substance is present in a finely divided particulate form, i. e. in a form where the active substance is present as particles, which are dispersed in an oil phase. The diameter of the active substance particles will generally not exceeded 50 µm. In particular at least 90% by weight of the active substance particles will have a diameter of below 30 µm, in particular below 20 µm. Advantageously, at least 40% by weight and in particular at least 60% by weight of the particles in the ODs according to the invention have diameters of below 10 µm. The OD formulation, hereinafter OD, of the present invention comprises the alkylether sulfate salt of the formula (I) and the one or more herbicide compounds, in particular glufosinate or a salt thereof. Preferably, the alkylether sulfate salt of the formula (I) contained in the OD is an ammonium salt of 2-propylheptyl ether sulfate or of isodecylether sulfate, where M+ is H4-mNR1m+, where R1 is as defined above and in particular selected from the group consisting of unbranched or branched alkyl radicals having preferably 1 to 4 carbon atoms, OH substituted alkyl radicals having preferably 2 to 4 carbon atoms, such as CH2CH2OH and CH2CH(OH)CH3, and m is an integer in the range of 1 to 4, in particular 1, 2 or 3, where the variable n is preferably in the range of 1 to 5, particularly in the range of 1 to 3, especially n is 2 and where the average of n is preferably in the range of 1.1 to 5.0, in in particular in the range of 1.5 to 4.5 and especially in the range of 1.7 to 3.5.

The amount of the alkylether sulfate salt of the formula (I) in such OD is usually in the range of from 1 to 45% by weight, in particular in the range of from 5 to 40% by weight, based on the total weight of the oil dispersion. Besides the alkylether sulfate salt of the formula (I), oil dispersions may comprise surface-active substances other than those of the formula (I) and, if appropriate, one or more auxiliaries, such as antifoam agents, thickeners, stabilizers (biocides), pH regulators and anticaking agents. Suitable surface-active substances other than those of the formula (I) are, preferably, the abovementioned anionic and nonionic surfactants. As a rule, the amount of surface-active substances other than those of the formula (I) will amount to from 0 to 30% by weight, in particular 0 to 20% by weight, based on the total weight of the OD according to the invention.

The herbicidal formulation according to the invention may be a physical mixture of at least one alkylether sulfate of the formula (I) with at least one herbicide compound, as defined herein. The formulation can, however, also be any desired combination of the alkylether sulfate of the formula (I) with at least one herbicide compound, where the alkylether sulfate of the formula (I) and the herbicide compound must not be formulated together. One example of the herbicidal formulation according to the invention, in which at least one alkylether sulfate of the formula (I) and at least one herbicide compound are not formulated together, is a two-component kit. Accordingly, the present invention also provides a two-component kit comprising a first component which comprises the alkylether sulfate of the formula (I), and a second component which comprises at least one herbicide compound, a liquid or solid carrier and optionally at least one surfactant and/or at least one customary auxiliary. In the method of the present invention, the alkylether sulfates of the formula (I) and at least one herbicide compound are applied to the undesired plants or their habitat. The order, in which the alkylether sulfate of the formula (I), the herbicide compound(s) and if present, the further herbicide are applied, is of minor importance. It is merely essential that the alkylether sulfate of the formula (I) and the herbicide compound(s) are present at the site of action at the same time, i.e. at the same time have contact with the plant to be controlled or are absorbed by this. As mentioned above, the alkylether sulfate of the formula (I) and the at least one herbicide may be co-formulated or separately formulated. In the latter case, the alkylether sulfates of the formula (I) and the at least one herbicide are typically applied as an aqueous spray liquor. Thus, the invention also relates to an aqueous spray liquor comprising i. at least one alkylether sulfate of the formula (I), as defined herein; and ii. at least one herbicide compound, as defined herein. For this, the alkylether sulfate of the formula (I) and the herbicide or suitable formulations thereof are typically mixed with the application water (make-up water) prior to application of the combination, i. e. the herbicide and the alkylether sulfate of the formula (I) are tank mixed. The concentration of the alkylether sulfate of the formula (I) in the spray liquor depends on its application rate, which is typically in the range from 10 g/ha to 2 kg/ha, in particular in the range of 20 g/ha to 1.5 kg/ha, especially in the range of 25 g/ha to 1.2 kg/ha, calculated as free acid (M+ = H).

The concentration of the herbicide compound in the aqueous spray liquor depends of its application rate, which is typically in the range from 10 g/ha to 1.2 kg/ha, in particular in the range of 20 g/ha to 1.0 kg/ha, especially in the range of 25 g/ha to 0.8 kg/ha, calculated as active herbicide compound. The amount of application water per hectare is generally in the range of 50 to 1000 l/ha. The aqueous spray liquor may have any pH value which is acceptable for agricultural purposes. Preferably, the aqueous spray liquor has a pH value in the range of 4 to 9, particularly in the range of 5 to 8, especially in the range of 5.5 to 7.5 as determined at 25 °C. In addition to water, the alkylether sulfate of the formula (I) and the herbicide (including the herbicide active ingredient and optionally formulation auxiliaries), the aqueous spray liquor may contain one or more further agriculturally active ingredients. Further agriculturally active ingredients may be selected from fungicides, insecticides, nematicides, safeners, fertilizers, micronutrients, biopesticides, nitrification inhibitors, urease inhibitors, and/or growth regulators. Combinations of herbicides and safeners may be particularly useful. Suitable safeners include (quinolin-8-oxy)acetic acids, 1- phenyl-5-haloalkyl-1H-1,2,4-triazol-3-carboxylic acids, 1-phenyl-4,5-dihydro-5-alkyl-1H- pyrazol-3,5-dicarboxylic acids, 4,5-dihydro-5,5-diaryl-3-isoxazol carboxylic acids, dichloroacetamides, alpha-oximinophenylacetonitriles, acetophenonoximes, 4,6-dihalo- 2-phenylpyrimidines, N-[[4-(aminocarbonyl)phenyl]sulfonyl]-2-benzoic amides, 1,8- naphthalic anhydride, 2-halo-4-(haloalkyl)-5-thiazol carboxylic acids, phosphorthiolates and N-alkyl-O-phenylcarbamates and their agriculturally acceptable salts and their agriculturally acceptable derivatives such amides, esters, and thioesters, provided they have an acid group.

The herbicidal formulation or the aqueous spray liquor according to the invention can be used for controlling undesired vegetation on crop area and on non-crop areas. The herbicidal formulation or the aqueous spray liquor according to the invention controls undesired plant growth on uncultivated surfaces very well, particularly at high application rates. In cultures such as wheat, rice, corn, soya and cotton, it is effective against weeds and harmful grasses without notably damaging the cultivated plants. This effect arises primarily at low application rates. The herbicidal formulation or the aqueous spray liquor allows for very efficiently control undesired vegetation on non-crop area and in crops. On non-crop area very efficient control is achieved at high application rates. Depending on the herbicide active compound, application of the spray liquor allows for efficient control of broad-leafed weeds and grass weeds in crops such as wheat, rice, corn, soybeans and cotton without causing any significant damage to the crop plants. This effect is mainly observed at low rates of application. The spray liquor is generally applied to the undesired plants mainly by spraying the leaves. Here, the application can be carried out by customary spraying techniques using spray liquor amounts of from about 10 to 1000 l/ha. Application of the spray liquor can be done before, during and/or after, preferably during and/or after, the emergence of the undesirable plants. When employed in plant protection, the amounts of glufosinate or salt thereof without formulation auxiliaries, are, depending on the kind of effect desired, from 10 g/ha to 2 kg/ha, in particular from 20 g/ha to 1.5 kg/ha, especially from 25 g/ha to 1.0 kg/ha, calculated as active herbicide compound. Depending on the particular application method, the herbicidal formulation or the aqueous spray liquor according to the invention can also be used in a further number of cultivated plants for eliminating undesired plants. The following cultures, for example, are contemplated: Allium cepa, Ananas comosus, Arachis hypogaea, Asparagus officinalis, Beta vulgaris spec. altissima, Beta vulgaris spec. rapa, Brassica napus var. napus, Brassica napus var. napobrassica, Brassica rapa var. silvestris, Camellia sinensis, Carthamus tinctorius, Caryailli Boinensis, Citrus limon, Citrus sinensis, Coffea arabica (Coffea canephora, Coffea liberica), Cucumis sativus, Cynodon dactylon, Daucus carota, Elaeis guineensis, Fragaria vesca, Glycine max, Gossypium hirsutum, (Gossypium arboreum, Gossypium herbaceum, Gossypium vitifolium), Helianthusannuus, Hevea brasiliensis, Hordeum vulgare, Humulus lupulus, Ipomoea batatas, Juglans regia, Lens culinaris, Linum usitatissimum, Lycopersicon lycopersicum, Malus spec., Manihot esculenta, Medicago sativa, Musa spec., Nicotiana tabacum (N. rustica), Olea europaea, Oryza sativa, Phaseolus lunatus, Phaseolus vulgaris, Picea abies, Pinus spec., Pisum sativum, Prunus avium, Prunus persica, Pyrus communis, Ribes sylvestre, Ricinus communis, Saccharum officinarum, Secale cereale, Solanum tuberosum, Sorghum bicolor (s. vulgare), Theobroma cacao, Trifolium pratense, Tritium aestivum, Tritium durum, Vicia faba, Vitis vinifera and Zea mays. Moreover, the herbicidal formulation or the aqueous spray liquor can also be used in cultures which are tolerant to the effect of herbicides through cultivation including genetic methods. Moreover, the herbicidal formulation or the aqueous spray liquor according to the invention can also be used in cultures which are tolerant to insects or fungal attack through cultivation including genetic methods. The term "crops" as used herein includes also (crop) plants which have been modified by mutagenesis or genetic engineering in order to provide a new trait to a plant or to modify an already present trait. Mutagenesis includes techniques of random mutagenesis using X-rays or mutagenic chemicals, but also techniques of targeted mutagenesis, in order to create mutations at a specific locus of a plant genome. Targeted mutagenesis techniques frequently use oligonucleotides or proteins like CRISPR/Cas, zinc-finger nucleases, TALENs or meganucleases to achieve the targeting effect. Genetic engineering usually uses recombinant DNA techniques to create modifications in a plant genome which under natural circumstances cannot readily be obtained by cross breeding, mutagenesis or natural recombination. Typically, one or more genes are integrated into the genome of a plant in order to add a trait or improve a trait. These integrated genes are also referred to as transgenes in the art, while plant comprising such transgenes are referred to as transgenic plants. The process of plant transformation usually produces several transformation events, which differ in the genomic locus in which a transgene has been integrated. Plants comprising a specific transgene on a specific genomic locus are usually described as comprising a specific “event”, which is referred to by a specific event name. Traits which have been introduced in plants or have been modified include in particular herbicide tolerance, insect resistance, increased yield and tolerance to abiotic conditions, like drought. Herbicide tolerance has been created by using mutagenesis as well as using genetic engineering. Plants which have been rendered tolerant to acetolactate synthase (ALS) inhibitor herbicides by conventional methods of mutagenesis and breeding comprise plant varieties commercially available under the name Clearfield®. However, most of the herbicide tolerance traits have been created via the use of transgenes. Herbicide tolerance has been created to glyphosate, glufosinate, 2,4-D, dicamba, oxynil herbicides, like bromoxynil and ioxynil, sulfonylurea herbicides, ALS inhibitor herbicides and 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, like isoxaflutole and mesotrione. Transgenes which have been used to provide herbicide tolerance traits comprise: for tolerance to glyphosate: cp4 epsps, epsps grg23ace5, mepsps, 2mepsps, gat4601, gat4621 and goxv247, for tolerance to glufosinate: pat and bar, for tolerance to 2,4-D: aad-1 and aad-12, for tolerance to dicamba: dmo, for tolerance to oxynil herbicies: bxn, for tolerance to sulfonylurea herbicides: zm-hra, csr1-2, gm-hra, S4-HrA, for tolerance to ALS inhibitor herbicides: csr1-2, for tolerance to HPPD inhibitor herbicides: hppdPF, W336 and avhppd-03. Transgenic corn events comprising herbicide tolerance genes are for example, but not excluding others, DAS40278, MON801, MON802, MON809, MON810, MON832, MON87411, MON87419, MON87427, MON88017, MON89034, NK603, GA21, MZHG0JG, HCEM485, VCO-Ø1981-5, 676, 678, 680, 33121, 4114, 59122, 98140, Bt10, Bt176, CBH-351, DBT418, DLL25, MS3, MS6, MZIR098, T25, TC1507 and TC6275. Transgenic soybean events comprising herbicide tolerance genes are for example, but not excluding others, GTS 40-3-2, MON87705, MON87708, MON87712, MON87769, MON89788, A2704-12, A2704-21, A5547-127, A5547-35, DP356043, DAS44406-6, DAS68416-4, DAS-81419-2, GU262, SYHTØH2, W62, W98, FG72 and CV127. Transgenic cotton events comprising herbicide tolerance genes are for example, but not excluding others, 19-51a, 31707, 42317, 81910, 281-24-236, 3006-210-23, BXN10211, BXN10215, BXN10222, BXN10224, MON1445, MON1698, MON88701, MON88913, GHB119, GHB614, LLCotton25, T303-3 and T304-40. Transgenic canola events comprising herbicide tolerance genes are for example, but not excluding others, MON88302, HCR-1, HCN10, HCN28, HCN92, MS1, MS8, PHY14, PHY23, PHY35, PHY36, RF1, RF2 and RF3. Insect resistance has mainly been created by transferring bacterial genes for insecticidal proteins to plants. Transgenes which have most frequently been used are toxin genes of Bacillus spec. and synthetic variants thereof, like cry1A, cry1Ab, cry1Ab- Ac, cry1Ac, cry1A.105, cry1F, cry1Fa2, cry2Ab2, cry2Ae, mcry3A, ecry3.1Ab, cry3Bb1, cry34Ab1, cry35Ab1, cry9C, vip3A(a), vip3Aa20. However, also genes of plant origin have been transferred to other plants. In particular genes coding for protease inhibitors, like CpTI and pinII. A further approach uses transgenes in order to produce double stranded RNA in plants to target and downregulate insect genes. An example for such a transgene is dvsnf7. Transgenic corn events comprising genes for insecticidal proteins or double stranded RNA are for example, but not excluding others, Bt10, Bt11, Bt176, MON801, MON802, MON809, MON810, MON863, MON87411, MON88017, MON89034, 33121, 4114, 5307, 59122, TC1507, TC6275, CBH-351, MIR162, DBT418 and MZIR098. Transgenic soybean events comprising genes for insecticidal proteins are for example, but not excluding others, MON87701, MON87751 and DAS-81419. Transgenic cotton events comprising genes for insecticidal proteins are for example, but not excluding others, SGK321, MON531, MON757, MON1076, MON15985, 31707, 31803, 31807, 31808, 42317, BNLA-601, Event1, COT67B, COT102, T303-3, T304- 40, GFM Cry1A, GK12, MLS 9124, 281-24-236, 3006-210-23, GHB119 and SGK321. Increased yield has been created by increasing ear biomass using the transgene athb17, being present in corn event MON87403, or by enhancing photosynthesis using the transgene bbx32, being present in the soybean event MON87712. Crops comprising a modified oil content have been created by using the transgenes: gm-fad2-1, Pj.D6D, Nc.Fad3, fad2-1A and fatb1-A. Soybean events comprising at least one of these genes are: 260-05, MON87705 and MON87769. Tolerance to abiotic conditions, in particular to tolerance to drought, has been created by using the transgene cspB, comprised by the corn event MON87460 and by using the transgene Hahb-4, comprised by soybean event IND-ØØ41Ø-5. Traits are frequently combined by combining genes in a transformation event or by combining different events during the breeding process. Preferred combination of traits are herbicide tolerance to different groups of herbicides, insect tolerance to different kind of insects, in particular tolerance to lepidopteran and coleopteran insects, herbicide tolerance with one or several types of insect resistance, herbicide tolerance with increased yield as well as a combination of herbicide tolerance and tolerance to abiotic conditions. Plants comprising singular or stacked traits as well as the genes and events providing these traits are well known in the art. For example, detailed information as to the mutagenized or integrated genes and the respective events are available from websites of the organizations “International Service for the Acquisition of Agri-biotech Applications (ISAAA)” (http://www.isaaa.org/gmapprovaldatabase) and the “Center for Environmental Risk Assessment (CERA)” (http://cera-gmc.org/GMCropDatabase), as well as in patent applications, like EP3028573 and WO2017/011288. The use the spray liquors according to the invention on crops may result in effects which are specific to a crop comprising a certain gene or event. These effects might involve changes in growth behavior or changed resistance to biotic or abiotic stress factors. Such effects may in particular comprise enhanced yield, enhanced resistance or tolerance to insects, nematodes, fungal, bacterial, mycoplasma, viral or viroid pathogens as well as early vigour, early or delayed ripening, cold or heat tolerance as well as changed amino acid or fatty acid spectrum or content. Furthermore, plants are also covered that contain by the use of recombinant DNA techniques a modified amount of ingredients or new ingredients, specifically to improve raw material production, e.g., potatoes that produce increased amounts of amylopectin (e.g. Amflora® potato, BASF SE, Germany). Furthermore, it has been found that the combination of the alkylether sulfate of formula (I) and the herbicide may also be suitable for the defoliation and/or desiccation of plant parts, for which crop plants such as cotton, potato, oilseed rape, sunflower, soybean or field beans, in particular cotton, are suitable. In this regard, herbicidal compositions have been found for the desiccation and/or defoliation of plants, processes for preparing these compositions, and methods for desiccating and/or defoliating plants using the herbicidal compositions according to the invention. As desiccants, herbicidal compositions according to the invention are suitable in particular for desiccating the above-ground parts of crop plants such as potato, oilseed rape, sunflower and soybean, but also cereals. This makes possible the fully mechanical harvesting of these important crop plants. Also of economic interest is the facilitation of harvesting, which is made possible by concentrating within a certain period of time the dehiscence, or reduction of adhesion to the tree, in citrus fruit, olives and other species and varieties of pomaceous fruit, stone fruit and nuts. The same mechanism, i.e. the promotion of the development of abscission tissue between fruit part or leaf part and shoot part of the plants is also essential for the controlled defoliation of useful plants, in particular cotton. Moreover, a shortening of the time interval in which the individual cotton plants mature leads to an increased fiber quality after harvesting. The combination of the alkylether sulfate of the formula (I) and the herbicide may be applied in or on permanent cropland, or on permanent crops. A permanent crop is one produced from plants which last for many seasons, rather than being re-planted after each harvest. Permanent crops are grown on permanent crop land in the form of agricultural land that includes grasslands and shrublands, e.g. used to grow grape vines or coffee; orchards used to grow fruit or olives; and forested plantations, e.g. used to grow nuts or rubber. It does not include, however, tree farms intended to be used for wood or timber. Preferred permanent croplands in the context of the present invention are plantations, grasslands and shrublands. Preferably, the permanent crops in the context of the present invention are plantation crops, and preferably are selected from the group consisting fruit crops and orchard crops (preferably fruit trees, citrus trees, mango trees, olive trees, grape vines, coffee, cocoa, tea, and berries (such as strawberries, raspberries, blueberries and currants)), Musaceae sp. crops (for example banana or plantain crops), nut trees (preferably almond trees, walnut trees, pistachio trees, pecan trees, hazelnut trees), oil palm trees, rubber trees, sugarcane and cotton. More preferably, the permanent crops are fruit trees (preferably pome fruit trees and stone fruit trees; preferred fruit trees are apple trees, pear trees, apricot trees, plum trees, cherry trees, peach trees), olive trees, grape vines, coffee, tea), Musaceae sp. crops (preferably banana crops or plantain crops), nut trees (preferably almond trees, walnut trees, pistachio trees, pecan trees, hazelnut trees), oil palm trees, rubber trees, and citrus crops (preferably lemon, orange or grapefruit crops). Even more preferably, the permanent crops are selected from the group consisting of apple trees, pear trees, apricot trees, plum trees, cherry trees, peach trees, olive trees, grape vines, coffee, tea, banana crops, nut trees (preferably almond trees, walnut trees, pistachio trees), oil palm trees, rubber trees, and citrus crops (preferably lemon, orange or grapefruit crops). Particularly preferably, the permanent crops are selected from the group consisting of apple trees, pear trees, apricot trees, plum trees, cherry trees, peach trees, olive trees, grape vines, coffee, tea, banana crops, almond trees, walnut trees, oil palm trees, rubber trees, lemon crops, orange crops and grapefruit crops. The combination of the alkylether sulfate of the formula (I) and the herbicide may also be applied on row crops and as well on specialty crops. Row crops can be planted in rows wide enough to allow it to be tilled or otherwise cultivated by agricultural machinery, machinery tailored for the seasonal activities of row crops. The particularity of row crops is that they are planted and cultivated on a seasonal or yearly basis. Therefore, such crops yield products and profit relatively quickly and predictably. A row crop is one produced from plants which last for many seasons, rather than being re-planted after each harvest. Examples of row crops include soybeans, corn, canola, cotton, cereals or rice, but as well sunflower, potato, dry bean, field pea, flax, safflower, buckwheat and sugar beets. Specialty crops are to be understood as fruits, vegetables or other speciality or plantation permanent crops such as trees, nuts, vines, (dried) fruits, ornamentals, oil palm, banana, rubber and the like, Horticulture and nursery crops, including floriculture, may also fall under the definition of speciality crops. Vegetable crops includes for example aubergine, beans, bell pepper, cabbage, chili, cucumber, eggplant, lettuce, melon, onion, potato, sweet potato, spinach and tomato. Plants being considered specialty crops are in general intensively cultivated. For weed control in vegetable crops, it may be desirable to shield the crops from contact with the spray solution that contains the herbicidal mixture according to the present invention. In general, the crops which may be treated with the combination of the alkylether sulfate of the formula (I) and the herbicide may be of conventional origin or may be herbicide tolerant crops, preferably crops, which are tolerant at least against one of glufosinate, glyphosate and/or dicamba. The combination of the alkylether sulfate of the formula (I) and the herbicide shows high herbicidal effects also against select crop plants, such as barley and soybean. This effect can be used to control crop plants in crop rotation methods of previously grown crop cultures. Typically, residual crop plants from previous rotation cycles remain after harvest and continue to grow within the subsequently grown crop variety. This reduces the yield since the crop plants of two different crop rotation cycles compete on the same locus of growth. The combination of the alkylether sulfate of the formula (I) and the herbicide may thus be applied to control residual crop plants from previous crop rotation cycles to allow for a homogeneous coverage with the subsequent crop plant. In a preferred embodiment, the combination of the alkylether sulfateof the formula (I) and the herbicide is applied once, twice or three times per Gregorian calendar year, i.e. in one application, in two applications or in three applications per year according to the Gregorian calendar. In a preferred embodiment, the herbicidal composition is applied twice per Gregorian calendar year, i.e. in two applications per year according to the Gregorian calendar. In an alternatively preferred embodiment, the combination of the alkylether sulfate of the formula (I) and the herbicide is applied one time per Gregorian calendar year, i.e. in one application per year according to the Gregorian calendar. In a preferred embodiment, the herbicidal composition is applied one time in about 12 months, i.e. in one application in about 12 months. In an alternative preferred embodiment, the combination of the alkylether sulfate of the formula (I) and the herbicide is applied between one and ten times per Gregorian calendar year, i.e. in up to ten applications per year according to the Gregorian calendar. This alternative preferred method is of particular usefulness in permanent crops, in particular those grown under tropical conditions; in which case weeds grow vigorously at any time of the year, and herbicide applications are to be repeated as soon as the previous treatment loses its effectiveness and weeds start to regrow. The invention includes the use and methods of application of the combination of the alkylether sulfate of the formula (I) and the herbicide for controlling undesirable vegetation in crops in a burndown program, wherein the crop is produced by genetic engineering or by breeding, are tolerant to one or more herbicides and/or resistant to pathogens such as plant-pathogenous fungi, and/or to attack by insects; preferably tolerant to glufosinate. Preferred are crops, which are tolerant to glufosinate, wherein the glufosinate tolerant crop plant is preferably selected from the group consisting of rice, canola, soybean, corn and cotton plants. Transgenic corn events comprising glufosinate tolerance genes are for example, but not excluding others, 5307 x MIR604 x Bt11 x TC1507 x GA21 x MIR162 (event code: SYN-Ø53Ø7-1 x SYN-IR6Ø4-5 x

Transgenic rice events comprising glufosinate tolerance genes are for example, but not excluding others, LLRICE06 (event code: ACS-OSØØ1-4, e.g. commercially available as Liberty Link™ rice), LLRICE601 (event code: BCS-OSØØ3-7, e.g. commercially available as Liberty Link™ rice) and LLRICE62 (event code: ACS-OSØØ2-5, e.g. commercially available as Liberty Link™ rice). The application of the herbicidal formulation or the aqueous spray liquor can take place in the pre-emergence or in the post-emergence method. If the herbicidal formulation is not very compatible for certain cultivated plants, then application techniques can be employed in which the herbicidal formulation is sprayed using the spraying device such that the leaves of the sensitive cultivated plants are where possible not affected, whereas the herbicidal formulation reaches the leaves of undesired plants growing underneath or the uncovered soil surface (post-directed, lay-by). The application of the combination of the herbicide and the copolymer CP provides an outstanding herbicidal activity against a broad spectrum of economically important harmful monocotyledonous and dicotyledonous harmful plants. Also here, post- emergence application is preferred. Specifically, examples may be mentioned of some representatives of the monocotyledonous and dicotyledonous weed flora, which can be controlled by the combinations according to the invention, without the enumeration being a restriction to certain species. In the context of the present text, reference may be made to growth stages according to the BBCH monograph “Growth stages of mono-and dicotyledonous plants“, 2nd edition, 2001, ed.

If the spray liquores are applied post-emergence to the green parts of the plants, growth likewise stops drastically a very short time after the treatment and the weed plants remain at the growth stage of the point of time of application, or they die completely after a certain time, so that in this manner competition by the weeds, which is harmful to the crops, is eliminated at a very early point in time and in a sustained manner. Applying the combination of the herbicide and the copolymer CP results in a rapidly commencing and long-lasting herbicidal action. As a rule, the rainfastness of the herbicide active compounds in the combination according to the present invention is advantageous. In particular when the herbicidal compositions are employed application rates may be reduced, a broader spectrum of broad-leaved weeds and grass weeds may be controlled, the herbicidal action may take place more rapidly, the duration of action may be longer, the harmful plants may be controlled better while using only one, or few, applications, and the application period which is possible to be extended. The abovementioned properties and advantages are of benefit for weed control practice to keep agricultural crops free from undesired competing plants and thus to safeguard and/or increase the yields from the qualitative and/or quantitative point of view. These herbicidal compositions markedly exceed the technical state of the art with a view to the properties described. Owing to their herbicidal and plant-growth-regulatory properties, the herbicidal compositions can be employed for controlling harmful plants in genetically modified crops or crops obtained by mutation/selection. These crops are distinguished as a rule by particular, advantageous properties, such as resistances to herbicidal compositions or resistances to plant diseases or causative agents of plant diseases such as particular insects or microorganisms such as fungi, bacteria or viruses. Other particular properties relate, for example, to the harvested material with regard to quantity, quality, storability, composition and specific constituents. Thus, for example, transgenic plants are known whose starch content is increased or whose starch quality is altered, or those where the harvested material has a different fatty acid composition. A particular aspect of the present invention also relates to a method of controlling undesired vegetation (e.g. harmful plants), which comprises applying the herbicidal compositions, preferably by the post-emergence method, to harmful or undesired plants, parts of said harmful or undesired plants, or the area where the harmful or undesired plants grow, for example the area under cultivation. In the context of the present invention, “controlling” denotes a significant reduction of the growth of the harmful plant(s) in comparison to the untreated harmful plants. Preferably, the growth of the harmful plant(s) is essentially diminished (60-79%), more preferably the growth of the harmful plant(s) is largely or fully suppressed (80-100%), and in particular the growth of the harmful plant(s) is almost fully or fully suppressed (90-100%). Thus, in a further aspect, the present invention relates to a method for controlling undesired plant growth, and/or controlling harmful plants, comprising the step of applying the aqueous spray liquor containing a combination of the herbicide and the copolymer CP, preferably in one of the preferred embodiments defined herein, onto the undesired plants or the harmful plants, on parts of the undesired plants or the harmful plants, or on the area where the undesired plants or the harmful plants grow. The aqueous spray liquor containing the combination of the herbicide and the copolymer CP may be used for controlling undesirable vegetation in burndown programs, in industrial vegetation management and forestry, in vegetable and perennial crops and in turf and lawn, wherein the herbicidal composition(s) can be applied pre- or post-emergence, i.e. before, during and/or after emergence of the undesirable plants. Preferred is the application as post-emergence treatment, i.e. during and/or after emergence of the undesirable plants. Herein, the herbicidal composition(s) are applied to a locus where crops will be planted before planting or emergence of the crop. In industrial weed management and forestry, it is desirable to control a broad range of weeds for an extended period of time. The control of large weeds, or taller species such as bushes or trees may also be desirable. Industrial weed management includes for example railway and right-of-way management, fence lines and non-crop land such as industrial and building sites, gravel areas, roads or sidewalks. Forestry includes for example the clearing of existing forest or bushland, the removal of regrowth after mechanical forest cutting, or the management of weeds under forestry plantations. In the latter case, it may be desirable to shield desirable trees from contact with the spray solution that contains the herbicidal mixture according to the present invention. The aqueous spray liquor containing the combination of the herbicide and the copolymer CP can also be used for weed control in turf and lawn provided the desirable grass species are tolerant to herbicidal composition. In particular, such herbicidal compositions can be used in desirable grass that has been rendered tolerant to the respective agrochemical active ingredient, e.g. glufosinate or its salts, by mutagenesis or genetic engineering. Glufosinate and its salts are non-selective systemic herbicides having a good post- emergence activity against numerous weeds and thus can be used in burndown programs, in industrial vegetation management and forestry, in vegetable and perennial crops and in turf and lawn. Therefore, the present invention also relates to a method for burndown treatment of undesirable vegetation in crops, comprising applying the aqueous spray liquor containing the combination of the herbicide and the copolymer CP to a locus where crops will be planted before planting (or seeding) or emergence of the crop. Herein, the herbicidal composition is applied undesirable vegetation or the locus thereof. The present invention also relates to a method for controlling undesirable vegetation, which method comprises applying the aqueous spray liquor containing the combination of the herbicide and the copolymer CP to a locus where undesirable vegetation is present or is expected to be present. The application may be done before, during and/or after, preferably during and/or after, the emergence of the undesirable vegetation. In one embodiment, the application is carried out before emergence of the crop, which is cultivated at the locus where the undesirable vegetation is present or is expected to be present. In another embodiment, the application is carried out before planting the crop. In burndown programs, the spray liquors can be applied prior to seeding (planting) or after seeding (or planting) of the crop plants but before the emergence of the crop plants, in particular prior to seeding. The spray liquors are preferably applied prior to seeding of the crop plants. For burndown, the spray liquors will generally be applied a date up to 9 months, frequently up to 6 months, preferably up to 4 months prior to planting the crop. The burndown application can be done at a date up to 1 day prior to emergence of the crop plant and is preferably done at a date prior to seeding/planting of the crop plant, preferably at a date of at least one day, preferably at least 2 days and in particular at least one 4 days prior to planting or from 6 months to 1 day prior emergence, in particular from 4 months to 2 days prior emergence and more preferably from 4 months to 4 days prior emergence. It is, of course, possible to repeat the burndown application once or more, e.g. once, twice, three times, four times or five times within that time frame. It is a particular benefit of the spray liquor containing the herbicide and the copolymer CP that the application of the spray liquor provides for a very good post-emergence herbicide activity, i.e. they show a good herbicidal activity against emerged undesirable plants. Thus, in a preferred embodiment of invention, the spray liquors are applied post-emergence, i.e. during and/or after, the emergence of the undesirable plants. It is particularly advantageous to apply the spray liquors post emergent when the undesirable plant starts with leaf development up to flowering. The herbicidal compositions are particularly useful for controlling undesirable vegetation, which has already developed to a state, which is difficult to control with conventional burndown mixtures, i.e. when the individual weed is taller than 10 cm (4 inches) or even taller than 15 cm (6 inches) and/or for heavy weed populations. In the case of a post- emergence treatment of the plants, the herbicidal compositions are preferably applied by foliar application. The spray liquors can be applied in conventional manner by using techniques as skilled person is familiar with. Suitable techniques include spraying, atomizing, dusting, spreading or watering. The type of application depends on the intended purpose in a well-known manner; in any case, they should ensure the finest possible distribution of the active ingredients according to the invention. In one embodiment, the spray liquors are applied to locus mainly by spraying, in particular foliar spraying of an aqueous dilution of the active ingredients of the mixture. Application can be carried out by customary spraying techniques using spray liquor rates of from about 10 to 2000 l/ha or 50 to 1000 l/ha (for example from 100 to 500 l/ha). The required application rate of the herbicide active compound via the spray liquor depends on the density of the undesired vegetation, on the development stage of the plants, on the climatic conditions of the location where the mixture is used and on the application method. In general, the rate of application of L-glufosinate or its salt is usually from 50 g/ha to 3000 g/ha and preferably in the range from 100 g/ha to 2000 g/ha or from 200 g/ha to 1500 g/ha of active substance (a.i.). The spray liquor containing the copolymer CP and the herbicide provide for a persistent herbicidal activity, even under difficult weathering conditions, which allows a more flexible application in burndown applications and minimizes the risk of weeds escaping. Apart from that, the spray liquor containing the copolymer CP and the herbicide provide for superior crop compatibility with certain conventional crop plants and with herbicide tolerant crop plants, i.e. their use in these crops leads to a reduced damage of the crop plants and/or does not result in increased damage of the crop plants. Thus, the spray liquor containing the copolymer CP can also be applied after the emergence of the crop plants. The spray liquor containing the copolymer CP may also show an accelerated action on harmful plants, i.e. they may affect damage of the harmful plants more quickly. The spray liquors containing the copolymer CP are also suitable for controlling weeds that are resistant to commonly used herbicides such as, for example, weeds that are resistant to glyphosate, weeds that are resistant to auxin inhibitor herbicides such as e. g.2,4-D or dicamba, weeds that are resistant to photosynthesis inhibitors such as e. g. atrazine, weeds that are resistant to ALS inhibitors such as e. g. sulfonylureas, imidazolinones or triazolopyrimidines, weeds that are resistant to ACCase inhibitors such as e. g. clodinafop, clethodim or pinoxaden or weeds that are resistant to protoporphyrinogen-IX-oxidase inhibitors such as e. g. sulfentrazone, flumioxazine, fomesafen or acifluorfen, for example the weeds that are listed in the International Survey of Resistant Weeds (http://www.weedscience.org/Summary/SpeciesbySOATable.aspx). In particular, they are suitable for controlling the resistant weeds that are resistant to glufosinate or its salts, such as listed in the International Survey of Resistant Weeds, for example ACCase

Examples The invention is elucidated in more detail by the examples hereinafter. The following abbreviations are used: 2-PH-2EO-SO3 ammonium salt of 2-propyl heptyl ether sulfate with 2 EO 2-EH-2EO-SO3 ammonium salt of 2-ethyl hexyl ether sulfate with 2 EO 2-PH-SO3 ammonium salt of 2-propyl heptyl sulfate 2-PH-0.88PO-3.523EO-SO3 ammonium salt of 2-propyl heptyl ether sulfate with 3.523 EO and 0.88 PO (Lutensol XL40) 2-PH-1.873PO-1.253EO-SO3 ammonium salt of 2-propyl heptyl ether sulfate with 1.253 EO and 1.873 PO 2-PH-0.78PO-2.7EO-SO3 ammonium salt of 2-propyl heptyl ether sulfate with 2.7 EO and 0.78 PO ethylene oxide (= CH2CH2O) PO 1,2-propylene oxide (= CH2CH(CH3)O) SLES sodium lauryl ether sulfate Glufosinate rac. Racemate of D- and L-glufosinates SL Aqueous soluble concentrate formulation Sodium 2-ethylhexyl sulfate was used as an 25% by weight aqueous solution. The alkylether sulfate of the formula (I) (ammonium salt of 2-propyl heptyl ether sulfate, 2-PH-2EO-SO3) and the other adjuvants (Ammonium salts of 2-EH-2EO-SO3 and PH- SO3) were used as aqueous concentrates. The herbicide compound (racemate of glufosinate and L-glufosinate, respectively) were used as aqueous solution of the respective glufosinate salt (TC) at the given concentration. The effect-improving action of the alkylether sulfate of the formula (I) on herbicides according to the invention was demonstrated by the following greenhouse experiments, which are hereinafter referred to as “inventive examples” (IE). For comparison, two different types of comparative examples were carried out. In the first type of comparative example (CE1), the herbicide compound was solely applied without any adjuvant. In the second type of comparative example (CE2), the herbicide compound was applied with ammonium salt of 2-propyl heptyl sulfate (2-PH-SO3), 2- ethyl hexyl ether sulfate (2-EH-2EO-SO3), sodium 2-ethly hexyl sulfate (commercially available as Texapon EHS) and sodium lauryl ether sulfate (SLES), respectively, which are used as an adjuvant, but not according to the formula (I). All details related to the applied alkylether sulfate of the formula (I), the herbicide compound and the comparative adjuvants are summarized in the following.

TC = technical concentrate A greenhouse study was conducted to evaluate the effect of the alkylether sulfates of formula (I) and other adjuvants on the weed control efficacy of glufosinate. Seedlings of grass plants (AVEFA, ECHCG, DIGSA and SETVI) and broadleaf weeds (KCHSC, CHEAL, AMAPA, AMATA and ABUTH) were grown to a height of 3 to 20 cm, depending on the plant habit in 10 x 10 x 10 cm pots filled with sandy planting soil (Limburgerhof soil). The weeds were treated with postemergence applications ofglufosinate ammonium at the respective application rates given in the following tables, either alone or combined with various amounts of the respective adjuvants. For this, the herbicide formulation and the respective adjuvant were introduced into tap water to obtain the spray liquor. All mixtures resulted in stable, clear spray solutions. The spray liquor was then applied to the plant a spray volume of 200 l/ha using a sprayer (XR Teejet 110015). The test period extended over 21 days. During this time, the plants were tended, and their response to the treatments with active compound was evaluated. The evaluation for the damage caused by the chemical compositions was carried out using a scale from 0 to 100%, compared to the untreated control plants. Here, 0 means no damage and 100 means complete destruction of the plants. The plants used in the greenhouse experiments belonged to the following species:
