Abstract

Herbicide safener combiantions consisting of A) an effective amount of a compound of the formula (1) or a salt thereof, in which R1 is phenyl which is unsubstituted or substituted, R2 is (C1-C6)alkyl, (C3-C6)cycloalkyl or phenyl, each of the 3 last-mentioned radicals is unsubstituted or substituted, R3 is hydrogen or a hydrocarbon radical having 1 to 18 C-atoms which is unsubstituted or substituted, and B) a herbicide selected form the group consisting of and florasulam, chloransulam, dicamba, diflufenzopyr; triclopyr, fluroxypyr, metribuzin, carfentrazone-ethyl, S.metolachlor, dimethenamide, dimethenamide-P or flufenacet and mixtures of the above herbicides, optionally in combination with toher herbicidal active ingredients can be used for effective selective cotrolling weeds in crop such as maize. 1
