Abstract

The invention relates to novel herbicidal synergistic active substance combinations which comprise tritosulfuron and conventional herbicidally effective compounds and, optionally, compounds that improve the compatibility of cultivated plants. The inventive synergistic herbicidal active substance combinations can be used with particularly good success in selectively killing weeds in different useful plant crops, especially in crops consisting of cereals and corn.

Description

The invention relates to new synergistic, herbicidal combinations of active ingredients Tritosulfuron and known herbicidally active compounds and optionally the Crop tolerance improving compounds include, and with be particularly good success for selective weed control in various uses plant crops can be used.

Tritosulfuron (N - [[[4-methoxy-6- (trifluoromethyl) -1,3,5-triazin-2-yl] amino] carbonyl] -2- trifluoromethyl) -benzenesulfonamide) is the subject of a broadly active herbicide Series of patent applications (see. DE-A 40 38 430, WO-A 97/10714). This effect However, substance has gaps in effectiveness.

Surprisingly, it has now been found that tritosulfuron when An Use with known, herbicidally active compounds from various substances Classes extremely synergistic effects with regard to the action against Un herbs shows, and that such broadly effective combination preparations especially advantageous for the selective control of weeds in crops such as e.g. B. wheat and corn can be used.

Surprisingly, it was also found that mixtures with Trito sulfuron with other known herbicidally active compounds together Use with the ver described below, the crop tolerance improving compounds (safeners / antidots), if necessary, additional advantageous Can achieve effects.

It has now surprisingly been found that the active ingredient com combinations of tritosulfuron and the active ingredients of group 1 listed above optionally in combination with active substances of group 2 and / or active substances of Group 3, with very good crop tolerance, a particularly high herbicide Have effectiveness and in different crops, especially in wheat, because but also used in maize and barley for selective weed control can be.

Surprisingly, the herbicidal activity of the active ingredient according to the invention combinations of tritosulfuron and compounds from group 1 above considerably 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 tritosulfuron and a safener / antidote ("active substances of group 3") in Combination with one or more of the group 1 active ingredients listed above with very good crop tolerance, a particularly high herbicidal activity and in different cultures, especially in cereals, especially wheat, but also in soy, potatoes, corn and rice for selective weed control can be used.

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

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 compounds listed above Group 3 are suitable, the harmful effects of tritosulfuron in combination with one or more of the group 1 active ingredients listed above, to which Cultivating crops almost completely, without losing the herbicidal effect affect weedliness.

The particularly advantageous effect of the especially before should be emphasized here combination partners from group 3, especially with regard to the Protection of cereal plants, such as. B. rice, wheat, barley and rye, as Crops.

In general, 1 part by weight of tritosulfuron 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 1.

The advantageous effect of crop tolerance of the active compound according to the invention Material combinations are 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 tritosulfuron or its mixtures with active ingredients of Group 1 and optionally with active ingredients of group 2 0.001 to 1000 weight parts, preferably 0.01 to 100 parts by weight and particularly preferably 0.1 to 10 Ge important parts of active ingredient of group 3.

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.

The following are suitable as solid carriers:
For example, ammonium salts and natural rock powders, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth and synthetic rock powders, such as highly disperse silica, aluminum oxide and silicates, as solid carriers for granules are possible: z. 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 ingredients including safeners, 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 substance 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 turned. 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- 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 - (X. Y / 100).

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