Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a carboxylic acid derivative substituted imino aryl compound, a preparation method thereof, a weeding composition and application. The compound is shown as a ralgene formula I, wherein Q represents Y represents halogen, halogenated alkyl or cyano; Z represents halogen; M represents CH or N; W represents OX5, SX5 or N (X5) 2; X represents -CX < 1 > X < 2 >-(alkyl) n-,-alkyl-CX < 1 > X < 2 >-(alkyl) n-or-(CH2) r-; and X3 and X4 each independently represent O, S, NH, N-alkyl or the like. The compound has excellent herbicidal activity against grassy weeds, broadleaf weeds, cyperaceae weeds and the like even at a low application rate, and has high selectivity against crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to an iminoaryl compound substituted by a carboxylic acid derivative, a preparation method thereof, a herbicidal composition and application thereof. Background technique [0002] The control of weeds is a crucial link in the process of realizing high-efficiency agriculture. Although there are various types of herbicides on the market, such as patent WO00 / 50409, etc. disclose the general formula compound 1-aryl-4-thiotriazine as a herbicide WO95 / 06641 discloses substituted 1-amino-3-phenyluracil compounds with herbicidal activity, and WO95 / 25725 discloses pyrimidyl aryl ketoxime compounds with herbicide and insecticide activity. However, the herbicidal properties of these known compounds against harmful plants and the selectivity against crops are not entirely satisfactory. And due to the continuous expansion of the market, the resistance of weeds, the service life of...
