ABSTRACT:
Combinations of herbicidal aromatic carboxylic acids and safenersThe 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).
