Combinations of herbicidal aromatic carboxylic acids and safeners The invention relates to a herbicide-safener combination, which comprises: (A) one or more herbicidal auxin type of aromatic carboxylic acids or salts thereof, for example dicamba, chloramben or 2,3,6-trichlorobenzoic acid (2,3,6-TBA), and (B) one or more safeners selected from the group consisting of: (B1) active compounds of the heterocyclic carboxylic acid type and their derivatives, preferably their esters or salts, selected from the group consisting of (B1.1) compounds of the phenylpyrazolin-3-carboxylic acid type, (B1.2) derivatives of the phenylpyrazolecarboxylic acid type, (B1.3) compounds of the triazolecarboxylic acid type, (B1.4) compounds of the 5-benzyl-, 5-phenyl- or 5,5-diphenyl-2-isoxazoline-3-carboxylic acid type, (B1.5) flurazole and (B1.6) dimepiperate, (B2) active compounds, or salts thereof, which, in addition to a herbicidal action against harmful plants, also have a safener action in crop plants such as rice, selected from the group consising of (B2.1) daimuron (B2.2) cumyluron (B2.3) methoxyphenone and (B2.4) CSB (B3) safening active N-acylsulfonamides selected from the group consisting of (B3.1) N′-acyl-N-benzoyl-aminobenzolsulfonamides or their salts (B3.2) acylsulfamoylbenzamides or salts thereof, with the exception of herbicide-safener combinations comprising dicamba or salts thereof and a safener selected from the group (B1.4) defined above. The invention is also directed to the respective method for protecting crops, the method for weed control using the combination and the use of compounds (B) for safening compounds (A).
A herbicide-safener combination, which comprises:
A method for selective control of weeds in crops of useful plants which comprises applying an herbicidally effective amount of one or more herbicides (A) and an crop-safening effective amount of one or more safeners (B) before, after or simultaneous with the application of herbicide (A) to the plants, parts of plants, plant seeds or the area under cultivation, herbicide (A) and safener (B) claimed in 1.
A method for protecting crop plants against phytotoxic side-effects of the herbicide dicamba or salts thereof, which comprises application of an amount, acting as an antidote, of mefenpyr-diethyl before, after or simultaneously with the application of dicamba to the plants, parts of plants, plant seeds or the area under cultivation.
A method for selective control of weeds in crops of useful plants which comprises applying an herbicidally effective amount of dicamba or salts thereof and an crop-safening effective amount of mefenpyr-diethyl to the plants, parts of plants, plant seeds or the area under cultivation.
