A pyrazole ether derivative of the formula ##STR289## where R 1 denotes ##STR290## X denoting oxygen and R 5 denoting hydrogen, alkyl of 1 to 16 carbon atoms which is unsubstituted or substituted by halogen, or alkoxy of 1 to 4 carbon atoms; alkenyl of 2 to 6 carbon atoms which is unsubstituted or chlorosubstituted; cycloalkyl of 3 to 8 carbon atoms; aralkyl having 1 to 3 carbon atoms in the alkyl and 6 to 10 carbon atoms in the aryl; aryl of 6 to 10 carbon atoms which is unsubstituted or substituted by fluoro, chloro, bromo, alkyl, alkoxy, and haloalkyl all of 1 to 4 carbon atoms, cyano, nitro, alkoxycarbonyl or alkoxycarbonylamino of 1 to 3 alkyl carbon atoms, R 2 denotes Y-R 7 , Y denoting oxygen or sulfur and R 7 denoting linear or branched alkyl of 1 to 18 carbon atoms which is unsubstituted or mono- or polysubstituted by fluoro, chloro, bromo, cyano, nitro, cycloalkyl, alkoxy or alkylthio of 1 to 4 carbon atoms; unsubstituted or fluoro-, chloro-, methoxy-, methyl- or trifluoromethyl-substituted aryloxy of 6 to 10 carbon atoms in the aryl; alkoxycarbonyl, alkylaminocarbamoyl or dialkylaminocarbonyl of 1 to 4 carbon atoms in the alkyl; acyloxy of 2 to 4 carbon atoms in the acyl; linear or branched alkenyl of 3 to 18 carbon atoms which is unsubstituted or mono- or polysubstituted by chloro; cycloalkyl of 3 to 8 carbon atoms which is unsubstituted or mono- or polysubstituted by alkyl, alkoxy, haloalkyl of 1 to 4 carbon atoms, fluoro, chloro or bromo; aryl of 6 to 10 carbon atoms which is unsubstituted or mono- or polysubstituted by fluoro, chloro, bromo, cyano, trifluoromethyl, nitro, or by alkyl, alkoxy, alkylthio, alkoxycarbonyl, alkylaminocarbonyl or dialkylaminocarbonyl, each alkyl being of 1 to 4 carbon atoms; aryl of 6 to 10 carbon atoms which is substituted by phenyl or phenoxy which in turn may be substituted by fluoro or chloro; or phenyl substituted by lower (C 1 to C 4 ) alkyl esters of (thio)-glycolic acid or (thio)-lactic acid via a (thio)-ether bond, and R 4 denotes hydrogen or methyl, and agriculturally acceptable acid addition salts thereof.
