<p>Novel cyclopropanecarboxylic acid derivatives There are described novel cyclopropanecarboxylic acid derivatives of the formula I < IMG > (I) wherein R1, R2 and R3 independently of one another are each hydrogen; halogen; C1-C8-alkyl which is unsubstituted or substituted by one or more substituents from the group: thiocyanogen, hydroxyl, halogen, C1-C4-alkoxy, C1-C4-alkylthio, acyloxy or R4; or they are each C3-C6-alkenyl which is unsubstituted or substituted by R5; or they are C3-C6-alkynyl which is unsubstituted or substituted by R6; or they are R7, whereby R4, R5, R6 and R7 are phenyl which is unsubstituted or substituted by a maximum of three identical or different substituents from the group: halogen, nitro, cyano, carboxylic acid, carboxylic acid alkyl ester, alkyl, alkenyl, alkynyl, haloalkyl, alkoxy or alkylthio; and X and Z are fluorine, chlorine, bromine or trifluoromethyl; and also the production of these novel derivatives. The active substances of the formula I or compositions containing them are used for protecting cultivated plants against harmful effects of agricultural chemicals.</p> |
