Abstract

The invention relates to novel, synergistic, herbicidal agent combinations, which comprise 2,6 di-substituted pyridine derivatives and known herbicidally effective compounds and/or safeners. Said combinations are particularly successful when used for selective weed control with various crop seedlings, in particular, cereals.

Description

The invention relates to new herbicidal, synergistic active ingredient combinations which known 2,6-disubstituted pyridine derivatives on the one hand and known herbicidal active compounds and / or safeners on the other hand exist and with special good success for selective weed control in various crops cultures can be used.

2,6-disubstituted pyridine derivatives are the subject of broad-spectrum herbicides Series of patent applications (cf. EP-A 447 004, WO-A 94/22833). The well-known However, pyridine derivatives have a number of efficacy gaps. The tolerable speed of these compounds against crops is also not among all Be conditions quite satisfactory.

Surprisingly, it has now been found that a number of known active ingredients from the series of 2,6-disubstituted pyridine derivatives when used together with known herbicidally active compounds from different classes of substances spoken show synergistic effects with regard to the action against weeds and particularly advantageous as a broadly effective combination preparation for selective loading control of weeds in crops such as. B. wheat used can be.

Surprisingly, it was also found that the 2,6-disubstituted pyridine Derivatives alone or together with known herbicidally active compounds common application with those described below, the Kulturpflanzenver Inertia-improving compounds (safeners / antidots) extremely well Prevent damage to the crop plants and act particularly advantageously as broad Combined preparation for the selective control of weeds in use plant crops, e.g. B. cereals can be used.

It has now surprisingly been found that the active ingredient com combinations of the 2,6-disubstituted pyridine derivatives of the formula (I) and those above Active ingredients of group 2 mentioned, if appropriate in combination with active ingredients groups 3 and 4, with a very good crop tolerance, a particularly high one Have herbicidal activity and in different crops, especially in Wheat, but also in rice, maize and barley as a selective weed herb fighting can be used.

Surprisingly, the herbicidal activity of the active ingredient according to the invention Combinations of compounds from groups 1 and 2 listed above significantly higher than the sum of the effects of the individual active ingredients.

There is therefore an unforeseeable synergistic effect and not just one Addition of effects. The new drug combinations are good in many cultures tolerated, whereby the new active ingredient combinations are otherwise difficult to control Control weeds well. The new combinations of active ingredients therefore represent a value full enrichment of selective herbicides.

It was also surprisingly found that the combination of active ingredients defined above nations from 2,6-disubstituted pyridine derivatives of the formula (I) and one Safener / antidote ("active substances of group 3") in combination with one or more of the above-mentioned active ingredients of group 2 with very good crop tolerance have a particularly high herbicidal activity and in different  Crops, especially in cereals and maize, especially wheat, but also in soy, Potatoes and rice can be used for selective weed control.

Surprisingly, it was also found that the herbicidal sub punch 2,4-dichlorophenoxy-acetic acid (2,4-D) and its derivatives as described above Can take over safener task.

The compounds diethyl-1- (2,4-dichlorophenyl) -4,5-dihydro-5-methyl-1H-pyrazole- 3,5-dicarboxylates (mefenpyr-diethyl), (1-methylhexyl) - [(5-chloro-8-quinolinyl) oxy] - acetate (Cloquintocet-mexyl) and ethyl 1- (2,4-dichlorophenyl) -5- (trichloromethyl) - 1H-1,2,4-triazole-3-carboxylates (fenchlorazole-ethyl) are described in the following patents described: DE-A-39 39 503, EP-A-191 736 and DE-A-35 25 205. 2,4-D is a well-known herbicide.

It is also surprising that from a large number of known Safeners or antidotes that are capable of the harmful effects of a herbicide to antagonize the crops, just the active ingredients listed above Group 3 are suitable, the damaging effect of compounds of the formula (I), in combination with one or more of the active ingredients listed above Group 2, almost completely cancel the crops without losing the affect herbicidal activity against the weeds.

The particularly advantageous effect of the especially before should be emphasized here preferred combination partners of the active ingredients of group 3, in particular obviously the protection of cereal plants, such as. B. rice, wheat, barley and Rye, as crops.

Under Plants are understood here as all plants and plant populations desired and undesirable wild plants or crops (including naturally occurring crops). Cultivated plants can be plants that by conventional breeding and optimization methods or by biotechno logical and genetic engineering methods or combinations of these methods can be obtained, including the transgenic plants and inclusive plant varieties that can or cannot be protected by plant breeders' rights.  

Plant parts should include all above-ground and underground parts and organs the plants, such as sprout, leaf, flower and root are understood, with playful leaves, needles, stems, stems, flowers, fruiting bodies, fruits and seeds as well as roots, tubers and rhizomes. To the plant parts also includes crops and vegetative and generative propagation material for example cuttings, tubers, rhizomes, cuttings and seeds.

The treatment according to the invention of the plants and parts of plants with the active ingredients substances takes place directly or by influencing their surroundings, living space or Storage room according to the usual treatment methods, e.g. B. by diving, spraying, Evaporation, misting, scattering, spreading and in the case of propagation material, in particular especially in the case of seeds, still by wrapping them in one or more layers.

The synergistic effect of the active compound combinations according to the invention is in be certain concentration ratios are particularly pronounced. However, they can Weight ratios of the active ingredients in the active ingredient combinations in relatively large Ranges can be varied. In general, 1 part by weight of the active ingredient Formula (I) 0.01 to 1000 parts by weight, preferably 0.05 to 500 parts by weight and particularly preferably 0.1 to 100 parts by weight of active ingredient of group 2.

The advantageous effect of crop tolerance of the active compound according to the invention combinations of substances is also special at certain concentration ratios very pronounced. However, the weight ratios of the active ingredients in the Drug combinations can be varied in relatively large areas. In general account for 1 part by weight of active ingredient of the formula (I), its salts or its Mixtures with active ingredients of group 2 0.001 to 1000 parts by weight, preferably 0.01 to 100 parts by weight and particularly preferably 0.1 to 10 parts by weight of one of the Above under (c), the crop plant tolerance improving Ver bindings (antidots / safeners).  

The active substance combinations can be converted into the usual formulations such as solutions, emulsions, wettable powders, suspensions, powders, dusts, Pastes, soluble powders, granules, suspension emulsion concentrates, active ingredient impregnated natural and synthetic materials as well as very fine encapsulation in polymers Fabrics.

These formulations are prepared in a known manner, e.g. B. by mixing of the active ingredients with extenders, i.e. liquid solvents and / or solid carriers gerstoffe, optionally using surfactants, so Emulsifiers and / or dispersants and / or foaming agents.

In the case of the use of water as an extender, e.g. B. also organic Lö be used as auxiliary solvents. Com as liquid solvent essentially in question: aromatics, such as xylene, toluene, or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, Chlorethylene or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, e.g. B. petroleum fractions, mineral and vegetable oils, alcohols, such as Butanol or glycol and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as Dimethylformamide and dimethyl sulfoxide, as well as water.

B. broken and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite and synthetic granules from inorganic and organic flours as well as granules from organic material such as sawdust, coconut shells, corn cobs and tobacco stems; as emulsifying and / or foam-generating agents come into question: z. B. nonionic and anionic emulsifiers such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for. B. alkylaryl polyglycol ethers, alkyl sulfonates, alkyl sulfates, aryl sulfonates and protein hydrolyzates; as dispersants come into question: z. B. lignin sulfitab lye and methyl cellulose.

Adhesives such as carboxymethyl cellulose, natural, can be used in the formulations and synthetic powdery, granular or latex-shaped polymers can be used, such as Gum arabic, polyvinyl alcohol, polyvinyl acetate, and natural phospholipids, such as cephalins and lecithins and synthetic phospholipids. Other additives can mineral and vegetable oils.

Dyes such as inorganic pigments, e.g. B. iron oxide, titanium oxide, ferro cyan and organic dyes such as alizarin, azo and metal phthalocyanine substances and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, Molybdenum and zinc can be used.

The formulations generally contain between 0.1 and 95 percent by weight of active substances, including the safe active substances, preferably between 0.5 and 90%.

The active compound combinations according to the invention are generally in the form of Ready formulations applied. The one in the drug combinations Active ingredients contained can also be used in individual formulations mixed, d. H. be used in the form of tank mixes.

The new drug combinations can be used as such or in their formulations continue to be used in a mixture with other known herbicides, ready formulations or tank mixes are possible. Also one Mixture with other known active ingredients, such as fungicides, insecticides, Akari ziden, nematicides, bird repellants, growth agents, plant nutrients fen and soil structure improvers is possible. For certain application  purposes, especially in the post-emergence process, it may also be advantageous to use the Formulations as additional additives plant-compatible mineral or vege stable oils (e.g. the commercial preparation "Oleo DuPont 11E") or ammonium salts such as B. include ammonium sulfate or ammonium rhodanide.

The new active ingredient combinations can be used as such, in the form of their formulations or the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules be applied. The application is done in the usual way, e.g. B. by pouring, Spraying, spraying, dusting or sprinkling.

The active compound combinations according to the invention can be used before and after emergence of the plants are applied, i.e. pre-emergence and post-emergence. she can also be worked into the soil before sowing.

A herbicide always has a synergistic effect if the herbicide Effect of the combination of active substances is greater than that of the individual active compound applied fabrics.

The expected effect for a given combination of two herbicides can be calculated as follows (cf. COLBY, SR: "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds 15, pages 20-22, 1967):
If X =% damage by herbicide A (active ingredient of formula I) at p kg / ha application rate
and Y =% damage by herbicide B (active ingredient of the formula II) at q kg / ha application rate
and E = the expected damage to herbicides A and B at p and q kg / ha application rate,
then E = X + Y - (XY / 100).

If the actual damage is greater than calculated, the combination is in its Effect superadditive, that is, it shows a synergistic effect.
