摘要

Compounds of the formula (I) IMAGE (I) where X1 and X2 independently of one another are halogen or haloalkyl, R1 is hydrogen, alkyl or alkoxyalkyl, R2 is alkyl or haloalkyl, and R3 is hydrogen, alkyl, alkenyl or alkynyl, can reduce, or entirely compensate, phytotoxic secondary effects of herbicides on crop plants and are therefore suitable as agents for the selective use of herbicides.
