Abstract
(EN)
The present invention relates to the technical field of pesticides, and specifically relates to an N-(1, 3, 4-oxadiazole-2-yl)aryl formamides or a salt thereof, a preparation method therefor, a herbicidal composition and a use thereof. The structural formula of the compound is shown in formula I. X denotes O, S, SO, SO 2 or NR 1; Y denotes halogen, cyano, cyanoalkyl, carboxyl, nitro or etc.; or -X-Y denotes unsubstituted or substituted five-membered or six-membered heterocyclyl or heteroaryl; Z denotes hydrogen, halogen, cyano, OR 4, -alkyl-OR 4, -O-alkyl-N(R 5) 2 or etc.; M denotes hydrogen, OR 6, SR 6, COR 6, COOR 6, CON(R 7) 2 or etc. The compound is low in use amount and excellent in herbicidal activity, has higher crop safety, and establishes good selectivity especially for important crops like paddy and etc.
