Problems solved by technology

The emulsifiable concentrate contains a large amount of organic solvents such as xylene and toluene, which not only causes serious pollution to the environment, but also wastes petrochemical resources.
Due to its very fine particle size, wettable powder often has dust flying during production and use, which not only endangers people's health, but also causes environmental pollution. A small amount of flying dust can easily cause phytotoxicity of crops

Abstract

The invention discloses an insecticidal water dispersible granule containing chlorfluazuron, the action mechanism of which is mainly to inhibit the synthesis of chitin, prevent the normal molt of insects to make the breeding of eggs, larval molting and growth of chrysalis abnormal, and prevent feathers of imagoes so as to play a role of insecticide. The water dispersible granule containing chlorfluazuron can be widely used for such antagonistic insects as diamond back moth, leaf miner, prodenia litura, rice leaf roller, beet armyworm and the like on vegetables, oranges, cottons, and rice.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a water-dispersible granule of chlorfluazuron. Background technique [0002] Chlorazuron, the common name in English is chofiuazuron, and its chemical name is 1-[3,5-dichloro-4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)phenyl]-3-(2, 6-difluorobenzoyl) urea, other names: impatabo, dichranuron. The main mechanism of action is to inhibit the synthesis of chitin, hinder the normal molting of insects, cause the hatching of eggs, molting of larvae, and the development of pupae are deformed, and the emergence of adults is blocked to play an insecticidal role. But it is only effective for immature insects, and the effect is slow. It has high activity against a variety of Lepidoptera pests, Orthoptera, Hymenoptera, and Diptera pests, and has good activity against insecticides that have developed resistance to organophosphates, carbamates, and pyrethroids. Control effect. [0003] Wi...
