COMPOSITION AGAINST ARTHROPODAL AND PLANT-PARASYTIC NEMATODE WORMS CONTAINING N-PHENYL-PYRAZOL DERIVATIVES, PROCESS FOR PRODUCING THE ACTIVE COMPONENTS AND PROCESS FOR KILLING ARTHROPODAL AND PLANT-PARASYTIC NEMATODE WORMS

摘要

The invention provides N-phenylpyrazole derivatives of the formula: CHEM wherein R1 represents alkyl optionally substituted by halogen, R2 represents alkyl, alkenyl or alkynyl optionally substituted by halogen, R3 represents a phenyl group substituted in the 2-position by halogen; in the 4-position by optionally halo substituted alkyl or alkoxy; and optionally in the 6-position by halogen; and m and n are independently 0, 1 or 2; which are active against arthropod, plant nematode, helminth and protozoal pests.
