Derivatives of 1,5-diphenyl-1,2,4-triazole-3-carboxylic acid for crop protection against the phytotoxic activity of herbicides

摘要

1,5-Diphenyl-1,2,4-triazole-3-carboxylic acid derivatives of formula IMAGE (I) wherein each of Ra and Rb, independently of the other, is halogen, C1-C5alkyl, C1-C5haloalkyl, C2-C5alkenyl, C2-C5alkynyl or cyano, n is zero or a number from 1 to 3 and OR is hydroxy, a phytophysiologically tolerable metal or ammonium salt radical, or an ester radical defined in the description, are capable of specifically antagonizing the phytotoxic action of herbicides. 1,5-Diphenyl-1,2,4-triazole-3-carboxylic acid derivatives of formula I and the preparation thereof, compositions containing these components as selective herbicides and the use of these two active ingredient components for controlling weeds in crops of useful plants are described.
