Description

Fungicidal drug combinations

The present invention relates to new active ingredient combinations which comprise a known triazolopyrimidine derivative, a known pyridinecarboxamide derivative and at least one further fungicide selected from the list consisting of a morpholine derivative, a benzophenone derivative, an azole derivative and a benzacetamide derivative. Derivative containing, and are very well suited for controlling phytopathogenic fungi.

It is already known that the triazolopyrimidine derivative 5-chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [l, 2,4] triazolo [l, 5- a] pyrimidine has fungicidal properties (see WO 98/46607). The effectiveness of this substance is good, but leaves at low application rates in some cases to be desired. The preparation of this compound is also known from WO 98/46607.

It is also known that the pyridinecarboxamide derivative 2-chloro-N- (4'-chloro [1'-biphenyl] -2-yl) -3-pyridinecarboxamide has fungicidal properties (cf DE-195 31 813 or US Pat EP-A-545 099). The effectiveness of this substance is good, but it leaves little to be desired at low application rates in some cases. The preparation of this compound is also known from DE 195 31 813 or EP-A-545 099.

Further, it is known that the morpholine derivative is (+ -) - cis-4- [3- [4- (1,1-dimethylethyl) phenyl] -2-methylpropyl] -2,6-dimethylmorpholine (Reference: DE-A -265 67 47), the benzophenone derivative (3-bromo-6-methoxy-2-methylphenyl) (2,3,4-trimethoxy-6-methylphenyl) -methanone (Reference: EP-A-897 904) Azole derivative 5 - [(4-chlorophenyl) methyl] -2,2-dimethyl-1- (1H-1,2,4-triazol-1-ylmethyl) cyclopentanol (Reference: EP-A-329 397) and the benzacetamide derivative (E) -2 - [(2,5-dimethylphenoxy) methyl] -alpha (methoxyimino) -N-methylbenzacetamide (reference: EP-A-398 692) has fungicidal properties Fabrics are good, but in some cases they leave a lot to be desired at low application rates, and the production of these compounds is also known.

Furthermore, fungicidal mixtures of two of the triazolopyrimidine derivative 5-chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [l, 2,4] triazolino [1, 5] a] pyrimidine in each case with boscalid (WO 04/045282), fenpropimorph (WO 2005/004608), metrafenone (WO 04/045288), metconazoles (WO 2005/032249) and with dimoxystrobin (WO 04/103075). The effectiveness of these blends is good, but at low levels it sometimes leaves much to be desired. Likewise fungicidal mixtures of two compounds of the pyridinecarboxamide derivative boscalid with other active ingredients are known (WO 97/10716, WO 97/39628, WO 99/31981). The effectiveness of these blends is good, but at low levels it sometimes leaves much to be desired.

Furthermore, ternary fungicide mixtures are known which contain the triazolopyrimidine derivative 5-chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [1,2-4 ₎ triazolo [1,1,5 -a] py-rimidine and a strobilurin derivative selected from pyraclostrobin and orysastrobin as a second mixture component and a third fungicide known (WO 2005/094583). The effectiveness of these blends is good, but at low levels it sometimes leaves much to be desired.

It has now been found that the new combinations of active substances, the 5-chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [l, 2,4] triazolo [l , 5-a] pyrimidine of the formula (I)

and

(1) 2-Chloro-N- (4'-chloro [1,1'-biphenyl] -2-yl) -3-pyridinecarboxamide (Reference: EP-A-545 099) of the formula (II)

calid

and (2) (+ -) - Cis-4- [3- [4- (1,1-dimethylethyl) phenyl] -2-methylpropyl] -2,6-dimethylmorpholine (Reference: DE-A-265 6747) Formula (III)

pimorph

and or

(3) (3-bromo-6-methoxy-2-methylphenyl) (2,3,4-trimethoxy-6-methylphenyl) -methanone (Reference: EP-A-897 904) of the formula (IV)

one

and or

(4) 5 - [(4-Chlorophenyl) methyl] -2,2-dimethyl-1- (1H-1,2,4-triazol-1-ylmethyl) cyclopentanol (Reference: EP-A-329 397) of the formula (V)

azole

and or

(5) (E) -2 - [(2,5-Dimethylphenoxy) methyl] -alpha (methoxyimino) -N-methylbenzacetamide

(Reference: see for example EP-A-535 928, EP-A-398 692, EP-A-596 692, JP-A-04182461) of the formula (VI) oxystrobin

contains very good fungicidal properties.

Surprisingly, the fungicidal action of the active compound combinations according to the invention is substantially higher than the sum of the effects of the individual active substances or the individual active substances and mixtures of two. So there is an unpredictable, true synergistic effect and not just an effect supplement.

With regard to effective resistance management and effective control of plant-pathogenic harmful fungi at the lowest possible application rates, mixtures of the present invention were based on an improved effect against harmful fungi (synergistic mixtures) with a reduced total amount of applied active substances.

It has also been found that by simultaneous or separate application of the compounds of the formula (I) and (II) and at least one other of the compounds (III), (IV), (V) and (VI) or when using the compound of the formula (I) and (II) and at least one other of the compounds (III), (IV), (V) and (VI) successively combat harmful fungi better than with the individual compounds or with the previously described binary mixtures.

The active ingredient of formula (I) is known (see WO-A-98 46607). The active compounds of the formulas (II), (III), (IV), (V) and (VI) are likewise known (cf references given).

It can be seen from the structural formula for the active ingredient of the formula (VI) that the compound can be present as an E or Z isomer. The compound (VI) can therefore be present as a mixture of different isomers or else in the form of a single isomer. Preference is given to compounds of the formula (VI) in which the compound of the formula (VI) is present as an E isomer.

It can be seen from the structural formulas for the compounds of formulas (IH) and (V) that the compounds can each be in the form of (-) or (+) enantiomers. The compounds of the formula (III) and (V) can therefore be in the form of a racemate or else in the form of a single enantiomer. Preference is given to the compounds of the formulas (III) and (V) in which the racemate is present. By the (-) - enantiomer is meant here in each case the enantiomer which rotates the oscillation plane of linearly polarized light of the sodium D line to the left.

The active ingredient combination according to the invention contains the active compounds of the formulas (I) and (II) and at least one further active ingredient selected from those of the formulas (III), (IV), (V) and (VI). It can also contain other fungicidal Zumischkomponenten beyond.

Emphasis is given to active compound combinations according to the invention which, in addition to the triazolopyrimidine derivative (I), 5-chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [l, 2,4] triazolo [l, 5-a] pyrimidine and the carboxamide derivative of the formula (II) contain a further mixing partner selected from the substances of the formulas (IH) to (VI).

In particular, the following active substance combinations are preferred:

5-Chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [l, 2,4] triazolo [l, 5-a] pyrimidine, boscalid and fenpropimorph

5-Chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [l, 2,4] triazolo [l, 5-a] pyrimidine, boscalid and metrafenone

5-Chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [l, 2,4] triazolo [l, 5-a] pyrimidine, boscalid and metconazole

5-Chloro-7- (4-methylpiperidin-1-yl) -6- (2,4,6-trifluorophenyl) [l, 2,4] triazolo [l, 5-a] pyrimidine, boscalid and dimoxystrobin

If the active ingredients in the erfϊndungsgemäßen drug combinations in certain weight ratios are present, the synergistic effect is particularly clear. However, the weight ratios of the active ingredients in the drug combinations can be varied within a relatively wide range.

In general, 1 part by weight of active compound of the formula (I)

0.1 to 10 parts by weight, preferably 0.2 to 5 parts by weight, of active compound of the formula (II),

and

0.2 to 20 parts by weight, preferably 0.5 to 10 parts by weight of active compound of the formula (III)

and or 0.1 to 10 parts by weight, preferably 0.2 to 5 parts by weight of active compound of the formula (IV)

and or

0.1 to 10 parts by weight, preferably 0.2 to 5 parts by weight, of active compound of the formula (V)

and or

0.1 to 10 parts by weight, preferably 0.2 to 5 parts by weight, of active compound of the formula (VI)

The mixing ratio is preferably to be chosen so that a synergistic mixture is obtained.

The active compound combinations according to the invention have very good fungicidal properties and can be used for controlling phytopathogenic fungi, such as Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes, Deuteromycetes, etc.

The compositions according to the invention are suitable for the protection of all crops cultivated in agriculture, in the greenhouse, in forests or in horticulture. In particular, these are cereal crops (such as wheat, barley, rye, millet and oats), corn, cotton, soy, rice, potatoes, sunflower, bean, coffee, turnip (eg sugar beet and fodder), peanut, vegetables (such as eg tomato, cucumber, onions and salad), wine, fruit (such as apple, banana, pear and cherry), lawn and ornamental plants.

In the treatment of seeds, cereals (such as wheat, barley, rye and oats), corn and rice are of particular importance.

The active compound combinations according to the invention also have a strong tonic effect in plants. They are therefore suitable for mobilizing plant-own defenses against attack by unwanted microorganisms.

In the present context, plant-strengthening (resistance-inducing) substances are to be understood as meaning those substances which are capable of stimulating the defense system of plants in such a way that the treated plants exhibit extensive resistance to these microorganisms with subsequent inoculation with undesired microorganisms.

Undesirable microorganisms in the present case are phytopathogenic fungi, bacteria and viruses. The erfϊndungsgemäßen substances can thus be used to protect plants within a certain period of time after treatment against the infestation by the said pathogens. The period within which protection is provided generally extends from 1 to 28 days, preferably 1 to 14 days after the treatment of the plants with the active ingredients or up to 200 days after a seed treatment.

The good plant tolerance of the active substance combinations in the concentrations necessary for the control of plant diseases makes it possible to treat whole plants (upper plants). terrestrial plant parts and roots), of plant and seed, and of the soil. The active compound combinations according to the invention can be used for foliar application or as a mordant.

Much of the damage to crops caused by phytopathogenic fungi is already produced by infestation of the seed during storage and after introduction of the seed into the soil and during and immediately after germination of the plants. This phase is particularly critical, as the roots and shoots of the growing plant are particularly sensitive and even minor damage can lead to the death of the entire plant. There is therefore a particular interest in protecting the seed and the germinating plant by the use of suitable agents.

The control of phytopathogenic fungi by the treatment of the seed of plants has long been known and is the subject of constant improvement. Nevertheless, there are a number of problems in the treatment of seeds that can not always be satisfactorily resolved. Thus, it is desirable to develop methods for protecting the seed and the germinating plant, which eliminate or at least significantly reduce the additional application of crop protection agents after sowing or after emergence of the plants. It is also desirable to optimize the amount of the active ingredient used in such a way that the seed and the germinating plant are best protected against attack by phytopathogenic fungi, without, however, damaging the plant itself by the active ingredient used. In particular, methods for treating seed should also include the intrinsic fungicidal properties of transgenic plants in order to achieve optimum protection of the seed and the germinating plant with a minimum of pesticides.

The present invention therefore also relates in particular to a method for protecting seed and germinating plants from the infestation of phytopathogenic fungi by treating the seed with an agent according to the invention.

The control of phytopathogenic fungi, which damage plants after emergence, takes place primarily through the treatment of the soil and the above-ground parts of plants with pesticides. Due to concerns about the potential impact of crop protection products on the environment and human and animal health, efforts are being made to reduce the amount of active ingredients applied.

One of the advantages of the present invention is that, because of the particular systemic properties of the agents of the invention, the treatment of the seed with these agents provides not only the seed itself but also the resulting plants after emergence protects phytopathogenic fungi. In this way, the immediate treatment of the culture at the time of sowing or shortly afterwards can be omitted.

It is likewise to be regarded as advantageous that the mixtures according to the invention can also be used in particular in the case of transgenic seed.

In the context of the present invention, the agent according to the invention is applied to the seed alone or in a suitable formulation. Preferably, the seed is treated in a state where it is so stable that no damage occurs during the treatment. In general, the treatment of the seed can be done at any time between harvesting and sowing. Usually, seed is used which has been separated from the plant and freed from flasks, shells, stems, hull, wool or pulp. For example, seed may be used which has been harvested, cleaned and dried to a moisture content below 15% by weight. Alternatively, seed may also be used which, after drying, e.g. treated with water and then dried again.

In general, care must be taken in the treatment of the seed that the amount of the agent and / or other additives applied to the seed is chosen so that germination of the seed is not impaired or the resulting plant is not damaged. This is especially important for active ingredients, which can show phytotoxic effects at certain application rates.

The agents according to the invention can be applied directly, ie without containing further components and without being diluted. In general, it is preferable to apply the agents to the seed in the form of a suitable formulation. Suitable formulations and methods for seed treatment are known to those skilled in the art and are described e.g. in the following documents: US 4,272,417 A, US 4,245,432 A, US 4,808,430 A, US 5,876,739 A, US 2003/0176428 A1, WO 2002/080675 A1, WO 2002/028186 A2.

The active compound combinations according to the invention are also suitable for increasing crop yield. They are also low toxicity and have good plant tolerance.

If appropriate, the active compound combinations according to the invention can also be used in certain concentrations and application rates as herbicides, for influencing plant growth and for controlling animal pests. If appropriate, they can also be used as intermediates and precursors for the synthesis of other active ingredients.

According to the invention, all plants and parts of plants can be treated. In this context, plants are understood as meaning all plants and plant populations, such as desired and undesired ones Wild plants or crops (including naturally occurring crops). Crop plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including the plant varieties which can or can not be protected by plant breeders' rights. Plant parts are to be understood as meaning all aboveground and subterranean parts and organs of the plants, such as shoot, leaf, flower and root, examples of which include leaves, needles, stems, stems, flowers, fruiting bodies, fruits and seeds, and roots, tubers and rhizomes. The plant parts also include crops and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offshoots and seeds.

The treatment according to the invention of the plants and plant parts with the active compound combinations takes place directly or by acting on their environment, habitat or storage space according to the usual treatment methods, e.g. by dipping, spraying, pouring, spraying, vaporizing, atomizing, spreading, spreading and in propagation material, in particular in seeds, further by single or multi-layer wrapping.

As already mentioned above, according to the invention all plants and their parts can be treated. In a preferred embodiment, wild-type or plant species obtained by conventional biological breeding methods, such as crossing or protoplast fusion, and plant cultivars and their parts are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The term "parts" or "parts of plants" or "plant parts" has been explained above.

It is particularly preferred according to the invention to treat plants of the respective commercially available or in use plant cultivars.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, nutrition), the treatment according to the invention may also give rise to superadditive ("synergistic") effects, for example reduced application rates and / or extensions of the activity spectrum and / or a Enhancement of the effect of the substances and agents which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to dryness or to water or soil salt content, increased flowering efficiency, easier harvest, acceleration of ripeness, higher crop yields, higher quality and / or higher nutritional value of the emmentary products, higher shelf life and / or workability of the harvested products possible, which go beyond the expected effects actually.

The preferred plants or plant cultivars to be treated according to the invention include all plants which have obtained genetic material by the genetic engineering modification which gives these plants particularly advantageous valuable properties ("traits") Examples of such properties are better plant growth. increased tolerance to high or low temperatures, increased tolerance to dryness or to bottoms, increased flowering efficiency, easier harvesting, acceleration of ripeness, higher crop yields, higher quality and / or higher nutritional value of the harvested products, higher shelf life and / or machinability Further and particularly emphasized examples of such properties are an increased defense of the plants against animal and microbial pests, such as insects, mites, phytopathogenic fungi, bacteria and / or viruses as well as an increased tolerance of the plants against certain herbicidal active substances. Examples of transgenic plants include the important crops such as cereals (wheat, rice), corn, soy, potato, cotton, rapeseed and fruit plants (with the fruits apples, pears, citrus fruits and grapes), with corn, soy, potato, cotton and rapeseed should be highlighted. Traits which are particularly emphasized are the increased defense of the plants against insects by toxins which are formed in the plants, in particular those which are produced by the genetic material from Bacillus thuringiensis (for example by the genes CryΙA (a), CryΙA (b ), CryΙA (c), CryllA, CrylllA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CrylF and combinations thereof) are produced in the plants (hereinafter "Bt plants"). Traits which are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulfonylureas, glyphosate or phosphinotricin (for example "PAT" gene). The genes conferring the desired properties ("traits") can also be present in combinations with one another in the transgenic plants. Examples of "Bt plants" are maize varieties, cotton varieties, soybean varieties and potato varieties sold under the trade names YIELD GARD® (eg maize , Cotton, soybean), KnockOut® (eg corn), StarLink® (eg corn), Bollgard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants are maize varieties, cotton varieties and soybean varieties, which are sold under the trade names Roundup Ready® (tolerance to glyphosate eg corn, cotton, soy), Liberty Link® (tolerance to phosphinotricin, eg rapeseed), IMI® (tolerance to Imidazolinone) and STS® (tolerance to sulfonylureas eg corn). As herbicide-resistant (conventionally grown on herbicide tolerance) plants are also sold under the name Clearfield® varieties (eg Corn). Of course, these statements also apply to future or future marketed plant varieties with these or future developed genetic traits.

The method for controlling harmful fungi is carried out by the separate or combined application of the compounds of the formula (I) and (II) and at least one further active compound selected from the compounds of the formula (III), (IV), (V) and (VI) or the mixtures of the compounds of the formula (I), (II) and at least one other active compound selected from the compounds of the formula (III), (IV), (V) and (VI) by spraying, spraying or

Dusting the seeds, plants or soils before or after sowing the plants or before or after emergence of the plants.

The active compound combinations according to the invention can be converted into the customary formulations depending on their respective physical and / or chemical properties, such as solutions, emulsions, suspensions, powders, dusts, foams, pastes, soluble powders, granules, aerosols, suspension-emulsion concentrates, Active substance-impregnated natural and synthetic substances as well as ultra-fine encapsulations in polymeric substances and in coating compositions for seeds, as well as ULV-KaIt and warm mist formulations.

These formulations are prepared in a known manner, e.g. by mixing the active compounds or the active compound combinations with extenders, ie liquid solvents, liquefied gases under pressure and / or solid carriers, optionally with the use of surfactants, ie emulsifiers and / or dispersants and / or foam-forming agents.

In the case of using water as an extender, e.g. also organic solvents can be used as auxiliary solvents.

The active substance content of the application forms prepared from the commercial formulations can vary within wide ranges. The active ingredient concentration of the use forms for controlling animal pests such as insects and acarids may be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight. The application is done in a custom forms adapted to the application forms.

The formulations for controlling unwanted phytopathogenic fungi generally contain between 0.1 and 95% by weight of active substances, preferably between 0.5 and 90%.

The active compound combinations according to the invention can be used as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, emulsifiable concentrates, emulsions, suspensions, wettable powders, soluble powders, dusts and granules. The application is carried out in a customary manner, for example by pouring, droplet irrigation, spraying, spraying, scattering, dusting, foaming, brushing, spreading, dry pickling, moist pickling, wet pickling, slurry pickling, encrusting, etc. The active compound combinations according to the invention can be present in commercially available formulations as well as in the formulations prepared from these formulations in admixture with other active ingredients, such as insecticides, attractants, sterilants, bactericides, acaricides, nematicides, fungicides, growth-regulating substances or herbicides.

When using the active compound combinations according to the invention, the application rates can be varied within a substantial range, depending on the mode of administration. In the treatment of parts of plants, the application rates of active ingredient combination are generally between 0.1 and 10,000 g / ha, preferably between 10 and 1,000 g / ha. In the case of seed treatment, the application rates of active compound combination are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. In the treatment of the soil, the application rates of active ingredient combination are generally between 0.1 and 10,000 g / ha, preferably between 1 and 5,000 g / ha.

The active compound combinations can be used as such, in the form of concentrates or generally customary formulations such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, e.g. by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersing and / or binding or fixing agent, water repellent, optionally siccatives and UV stabilizers and optionally dyes and pigments and other processing aids.

The good fungicidal action of the active compound combinations according to the invention is evident from the examples below. While the individual active substances have weaknesses in the fungicidal action, the combinations show an effect that goes beyond a simple summation of effect.

A synergistic effect is always present in fungicides when the fungicidal action of the active ingredient combinations is greater than the sum of the effects of the individually applied active ingredients.

The expected effect for a given combination of 2 or 3 drugs can be calculated according to SR Colby ("Calculating Synergistic and Antagonistic Responses of Herbicide Combinations", Weeds 1967, 15, 20-22) as follows: If

X means the efficiency when using the active substance A in an application rate of m g / ha,

Y means the efficiency when using the active ingredient B in an application rate of n g / ha,

Z means the efficiency when using the active ingredient C in an application rate of r g / ha,

El means the efficiency when using the active compounds A and B in application rates of m and n g / ha means and

E2 means the efficiency when using the active compounds A and B and C at application rates of m and n and r g / ha,

then

E ₁ = X ₊ Y - X ^ ¹ 100

and for a combination of 3 agents:

(X - Y + X - Z + Y - Z) X Y - Z

E2 = X + Y + Z - +

100 10 000

The efficiency is determined in%. It means 0% an efficiency that corresponds to that of the control, while an efficiency of 100% means that no infestation is observed.

The invention is illustrated by the following examples. However, the invention is not limited to the examples. example 1
