The invention concerns 4,5-di(trifluoromethyl)pyrazoles of formula (I) and their salts, in which R1 designates C1-4 alkyl, C1-C4 alkyl halide; R2 designates H, halogen; R3 designates CN, halogen, C1-C4 alkyl, C1-C4 alkyl halide; R4 designates H, NO2, CN, halogen, -O-X2-R5, -O-CO-X2-R5, -N(X2-R5)(X3-R6), -N(X2-R5)-SO2-X3-R6-N(SO2-X2-R5)(SO2-X3-R6) -N(X2-R5)(CO-X3-R6), -N(X2-R5)(O-X3-R6), -S-X2-R5, -SO-X2-R5, -SO2-X2-R5, -SO2-O-X2-R5, -SO2-N(X2-R5)(X3-R6), -CO-X2-R5, -C(=NOR7)-X2-R5, -CO-O-X2-R5,-CO-S-X2-R5, -CO-N(X2-R5)(X3-R6) or -CO-N(X2-R5)(O-X3-R6); and X1, X2, X3 designate a chemical bond or ethene-1,2-diyl-, a methylene-, ethylene- or propane-1,3-diyl chain which can have 1 or 2 substituents: halogen, CN, COOH, C1-C4 alkyl, C1-C4 alkyl halide, C1-C4 alkoxycarbonyl, C1-C4 alkoxy, di-(C1-C4 alkyl)amino, C1-C6 alkyl halide and/or optionally substituted phenyl, wherein the methylene-, ethylene- or propane-1,3-diyl chain can additionally carry a hydroxy, amino or C1-C4 alkyl amino group. The invention also concerns the use of these substances as herbicides and for desiccating/defoliating plants.

L'invention concerne des 4,5-di(trifluorométhyl)pyrazoles de formule (I) et leurs sels, où R1 est un alkyle en C1-C4, un halogénure d'alkyle en C1-C4; R2 est H, un halogène; R3 est CN, un halogène, un alkyle en C1-C4, un halogénure d'alkyle en C1-C4 ; R4 correspond à H, NO2, CN, un halogène, -O-X2-R5, -O-CO-X2-R5, -N(X2-R5)(X3-R6), -N(X2-R5)-SO2-X3-R6-N(SO2-X2-R5)(SO2-X3-R6) -N(X2-R5)(CO-X3-R6), -N(X2-R5)(O-X3-R6), -S-X2-R5, -SO-X2-R5, -SO2-X2-R5, -SO2-O-X2-R5, -SO2-N(X2-R5)(X3-R6), -CO-X2-R5, -C(=NOR7)-X2-R5, -CO-O-X2-R5,-CO-S-X2-R5, -CO-N(X2-R5)(X3-R6) ou -CO-N(X2-R5)(O-X3-R6); et X1, X2, X3 désignent une liaison chimique ou une chaîne éthène-1,2-diyle, méthylène, éthylène ou propane-1,3-diyle qui peut porter 1 ou 2 substituants : un halogène, CN, COOH, alkyle en C1-C4, halogénure d'alkyle en C1-C4, alcoxycarbonyle en C1-C4, alcoxy en C1-C4, di(alkyle en C1-C4)amino, halogénure d'alkyle en C1-C6 et/ou phényle facultativement substitué, la chaîne méthylène, éthylène ou propane-1,3-diyle pouvant également porter un groupe hydroxy, amino ou alkyle en C1-C4-amino. L'invention concerne également l'utilisation de ces substances comme herbicides et comme agent de dessiccant/défoliant pour les plantes.
