The invention belongs to the technical field of agricultural chemicals, and particularly relates to an N-(1,3,4-oxadiazol-2-yl)arylcarboxamide compound or a salt thereof, a preparation method, a herbicidal composition and a use thereof. The compound is as shown in the following Formula I:

##STR00001## wherein X represents O, S, SO, SO.sub.2 or NR.sub.1; Y represents halogen, cyano, cyanoalkyl, carboxyl, nitro, etc.; or —X—Y represents unsubstituted or substituted five- or six-membered heterocyclyl or heteroaryl; Z represents hydrogen, halogen, cyano, OR.sub.4, -alkyl-OR.sub.4, —O-alkyl-N(R.sub.5).sub.2, etc., M represents hydrogen, OR.sub.6, SR.sub.6, COR.sub.6, COOR.sub.6, CON(R.sub.7).sub.2, etc. The compound has advantages of a low dosage for use, excellent herbicidal activity, and higher crop safety, especially good selectivity for key crops such as rice.

The present invention relates to agricultural methods and the use of an insecticidal active carboxamide derivative in seed treatment and soil application methods. The insecticidal carboxamide derivative is highly suitable alone or in combination with other active agricultural ingredients for controlling animal pests such as insects and/or spider mites and/or nematodes by treating the soil/growth substrate by drenching or drip application or dipping or soil injection.
