Abstract

The invention belongs to the technical field of pesticides, and particularly relates to an isoxazoline oxime formate compound as well as a preparation method, a weeding composition and application thereof. The isoxazoline oxime formate compound is shown as a general formula I, and in the general formula I, Y represents halogen, halogenated alkyl, cyano, nitro or amino; Z represents hydrogen, halogen or hydroxyl; Q represents or M represents CH or N; X1, X2, and X3 each independently represent hydrogen or the like; and X4 and X5 independently represent hydrogen, halogen, cyano, nitro or the like. The compound has excellent herbicidal activity on gramineous weeds, broadleaf weeds and the like at a low application rate, and has high selectivity on crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an isoxazoline carboxylate oxime ester compound, a preparation method thereof, a herbicidal composition and an 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 The use of herbicides, WO2016 / 095768A1 discloses a uracil compound containing isoxazoline and its use as a herbicide. 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 drugs and the economics of drugs, as well as people's increasing attention to the envir...
