Problems solved by technology

[0006] (1) Through the rational compounding of fluomepyrone and benzoylurea, it can effectively prevent and control pests. By adding piperonylcycline and cyclobutylformyl chloride to a four-necked flask, intermediate A is obtained, and hydrated Hydrazine, intermediate B was obtained, polyethylene glycol and KOH were added to intermediate B, intermediate C was obtained, cyclohexane, paraformaldehyde and hydrochloric acid were added, PCl was added dropwise 3 , to obtain intermediate D, adding ethylene glycol butyl ether, sodium hydroxide and water to obtain the synergist, by adding the synergist, it solves the problem that the existing pesticide composition requires high-concentration pesticide spraying or multiple Repeated application of pesticides, resulting in waste of resources and unfriendly to the soil;

Abstract

The invention discloses a composition containing pyridalyl and benzoylurea, which is prepared by the following steps: respectively adding a solvent toluene, an intermediate A and hydrazine hydrate into a reaction flask with a stirrer, a heating jacket and a reflux condensing tube, starting mechanical stirring, cooling to room temperature, installing a reflux water segregator, azeotropic toluene, cooling the system to room temperature to obtain an intermediate B, and adding polyethylene glycol and KOH into the intermediate B to obtain an intermediate C. According to the invention, a synergistic additive is added into a pesticide composition and sprayed, the synergistic additive inhibits the effect of oxidase of insects after entering the bodies of the insects, the oxidase plays a main role in metabolism and degradation of insecticides, and metabolism and degradation of the insecticides can be reduced by inhibiting the oxidase, so that the synergistic effect is achieved.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a composition containing trifluroxyfen and benzoylureas. Background technique [0002] The chemical formula of triflurome is C 18 h 14 C l4 f 3 NO 3 It is mainly used to prevent and control the larvae of Lepidoptera pests. It is sprayed at the young larvae of diamondback moth. It is resistant to rain and does not cause phytotoxicity to crops. Benzoylurea pesticides kill pests by acting on insect larvae and preventing the peeling process. , has excellent control effect on leaf-eating caterpillars such as fruit trees, has a unique killing mechanism on thrips, rust mites, and whitefly, and is suitable for controlling pests that are resistant to synthetic pyrethrins and organophosphorus pesticides. Long term, safe for crops, corn, vegetables, citrus, cotton, potatoes, grapes, soybeans and other crops can be used, the agent will not cause the rampant piercing-sucking pests, mild effect ...
