Definitions

• the object of the present application was to provide a new synergistic herbicidal active ingredient combination based on a new active ingredient from the class of 3-phenylpyrazoles and an active ingredient from the class of heteroaryloxyacetamides with pronounced activity against both monocot and dicot weeds.
• EP 361 1 14 generally describes 3- (4-chlorophenyl) pyrazoles as herbicides for controlling a wide variety of weeds in the pre-emergence and in the post-emergence, in particular in rice crops.
• JP 03 163 063 also describes the use of 3-substituted phenylpyrazoles for herbicidal use in agriculture.
• the active ingredient can be used alone or as a broadly effective combination preparation, for selective weed control - both of monocotyledon and dicotyledon weeds, in the pre-emergence and post-emergence process - in monocotyledon and dicotyledon crop plants, such as maize, wheat, barley, rice, soybean and Cotton are used, whereby a number of economically important (problem) weeds and grasses are safely controlled.
• the present invention relates to herbicidal, synergistic agents, characterized by an effective content of an active ingredient combination consisting of 4-bromo-l-memyl-5-trifluoromethyl-3- (2-fluoro-4-chloro-5-isopropoxycarbonylphenyl) pyrazole of formula (I)
• R 1 represents in each case optionally substituted C r C 4 alkyl, C 3 -C 4 alkenyl or C r C 4 alkoxy and
• R 2 represents in each case optionally substituted C ) -C 4 alkyl, C 3 -C 4 alkenyl or phenyl.
• compositions according to the invention of the compound of the above-mentioned formula (I) with (5-trifluoromethyl-l, 3,4-thiadiazol-2-yl-oxy) - acetic acid-N-isopropyl-N- (4-fluorophenyl) - are particularly preferred amide of the formula (II-l)
• the compound of formula (II-1) is known, e.g. from EP-A 348 737 and US 4 968 342.
• the herbicidal activity of the active compound combination according to the invention is considerably higher than the sum of the effects of the individual active compounds.
• the active substance combinations according to the invention can e.g. can be used in the following plants:
• Trifolium Ranunculus, Taraxacum.
• 1 part by weight of active compound of the formula (I) comprises 0.001 to 1000 parts by weight, preferably example, 0.01 to 100 parts by weight and particularly preferably 0.1 to 30 parts by weight of active ingredient of the formula (II).
• the active ingredients or combinations of active ingredients can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspension
• Emulsion concentrates active ingredient-impregnated natural and synthetic substances as well as very fine encapsulation in polymeric substances
• formulations are prepared in a known manner, for example by mixing the active ingredients with extenders, that is to say liquid solvents and / or solid carriers, optionally using surface-active agents
• Agents ie emulsifiers and / or dispersants and / or foam-generating agents
• organic solvents can, for example, also be used as auxiliary solvents.
• auxiliary solvents are aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylene or methylene chloride.
• aliphatic hydrocarbons such as cyclohexane or paraffins, e.g.
• 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 : eg broken and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite as well as synthetic granules from inorganic and organic flours as well as granules from organic material such as sawdust, coconut shells, corn cobs and tobacco stalks; suitable emulsifiers and / or foam-generating agents are, for example, nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkyl sulfonates, alkyl sul
• Adhesives such as carboxymethyl cellulose, natural and synthetic powders, granular or latex-shaped polymers, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, and also natural phosphopides, such as cephalins and lecithins and synthetic phospholipids, can be used in the formulations.
• Other additives can be mineral and vegetable Be Ole
• Dyes such as inorganic pigments, for example iron oxide, titanium oxide, ferrocyan blue and organic dyes such as alizarin, azo and metal phthalocyanine dyes 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 compound, preferably between 0.5 and 90%
• the active compound combinations according to the invention are generally used in the form of ready-to-use formulations.
• the active compounds contained in the active compound combinations can also be mixed in individual formulations during use, that is to say applied in the form of tank mixtures
• the new combinations of active substances can be used as such or in their form also in a mixture with other known herbicides, ready-to-use formulations or tank mixtures being possible.
• a mixture with other known active substances such as fungicides, insecticides, acaricides, nematicides, and protective substances Bird feed, growth substances, plant nutrients and soil structure improvers are possible
• mineral or vegetable oils eg the commercial preparation "Oleo Dupont 11E"
• Absorb ammonium salts such as ammonium sulfate or ammonium rhodanide
• the new combination of active substances can, 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. They are used in the customary manner, for example by watering, spraying, spraying, dusting or scattering.
• the application rates of the active compound combinations according to the invention can be varied within a certain range; they hang among other things of the weather and the
• the application rates are between 0.01 and 10 kg per ha, preferably between 0.05 and 5 kg per ha, particularly preferably between 0.1 and 3.0 kg per ha.
• the active compound combinations according to the invention can be applied before and after emergence of the plants, that is to say in the pre-emergence and post-emergence process.
• a herbicide always has a synergistic effect if the herbicidal action of the active compound combination is greater than that of the individual active compounds applied.
• Y % damage by herbicide B (active ingredient of group 2) at q kg / ha application rate
• the effect of the combination is super-additive, i.e. it shows a synergistic effect.
• Seeds of the test plants are sown in normal soil and after 24
• Test plants with a height of 5 to 15 cm are sprayed with the active substance preparations, so that the respectively desired amounts of active substance are applied per unit area.
• the concentration of the spray liquors is chosen so that the desired amounts of active compound are applied in 500 l of water per ha.
• the test plants are grown in the greenhouse under controlled conditions (Temperature, humidity, light) held until evaluation. After three weeks, the degree of damage to the plants is rated in% damage in comparison to the development of untreated control plants.
