Herbicide combination

摘要

A herbicide-safener combination contains (A) one or more compounds of formula (I) or their salts, and (B) one or more safeners. In the formula (I), A stands for nitrogen or a CR group, R designating hydrogen, alkyl, halogen and haloalkyl; R stands for hydrogen or an optionally substituted residue from the series composed of alkyl, alkoxy, alkoxyalkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aralkyl and aryl; R stands for hydrogen, halogen or optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylamino or dialkylamino having 1-6 carbon atoms; R stands for hydrogen, halogen or optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylamino or dialkylamino having 1-6 carbon atoms; R-R independently stand for hydrogen, halogen, cyano, thiocyanato or optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, alkylcarbonyl, alkoxycarbonyl, alkylaminocarbonyl having 1-3 carbon atoms; and R stands for hydrogen, halogen, cyano, thiocyanato or optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, alkylcarbonyl, alkoxycarbonyl, alkylaminocarbonyl having 1-3 carbon atoms. In the above-mentioned residues, each of the alkyl and alkylene groups can have 1-6 C atoms, each of the alkenyl and alkinyl groups can have 2-6 C atoms, each of the cycloalkyl groups can have 3-6 C atoms and each of the aryl groups can have 6-10 C atoms.
