ANTIDOTUM COMPOSITION COMPRISING 4,5-PYRAZOLINE-3-CARBOXYLIC ACID ESTER DERIVATIVES, HERBICIDAL COMPOSITION WITH REDUCED PHYTHOTOXICITY AND USE THEREOF, THE NOVEL ANTIDOTES AND THEIR PREPARATIONS

摘要

The compositions of the present invention contain 4,5-pyrazoline-3-carboxylic acid ester derivatives of formula (I) as antidotes. In formula (I), X is independently halogen or C 1-4 haloalkyl, n is 1, 2 or 3, R 1 is hydrogen, C 1-4 alkyl or (C 1-4 alkoxy) - (C 1-4) alkyl), R 2 and R 3 are independently hydrogen, C 1-6 alkyl, C 2-6 alkenyl, C 2-6 alkynyl, C 3-6 cycloalkyl, mono- or di (C 1-4 alkoxy); ) (C 1 -C 4 alkyl), (C 1 -C 6 alkyl) carbonyl, cyano, carboxyl, (C 1 -C 12 alkyl) oxycarbonyl, (C 1 -C 4 alkoxy) carbonyl C 1-4 alkyl, di (C 1-4 alkyl) aminocarbonyl or optionally substituted phenyl which may be substituted by one or more halogen atoms, C 1-4 alkyl, C 1-4 alkoxy or cyano , or R 2 and R 3 together form a - (CH 2) 4 or - (CH 2) 5 - group which together with the 5-atom of the pyrazoline ring forms a 5- or 6-membered ring. ŕ
