Problems solved by technology

[0006] (1) By adding allyl polyoxyethylene ether into a four-necked flask, adding thioglycolic acid, ammonium persulfate aqueous solution, and 2-pentenoic acid dropwise to the flask to obtain product A, adding vinyl to product A Trimethoxysilane, add thioglycolic acid and ammonium persulfate aqueous solution dropwise to the flask to obtain the auxiliary agent A. By adding the auxiliary agent A, it is solved that the existing pesticide composition is prone to agglomeration and poor dispersion when it is diluted and used. Poor wettability and high surface tension during application, making it difficult to wet and spread on the leaves of target organisms, reducing the efficacy of the drug;

Abstract

The invention discloses an insecticidal composition containing pyridalyl, relates to the field of pesticides and aims to solve the problems that existing pesticide composition is easy to agglomerate and poor in dispersity when being diluted for use, is poor in wettability and large in surface tension when being applied, is not easy to wet and spread on target biological leaf surfaces, is low in pesticide effect and poor in water solubility, and is easily adsorbed by soil. Physical stability of a suspension system is achieved through the synergistic effect of electrostatic repulsion and steric hindrance, methoxyl groups can be closely arranged in an umbrella shape, wetting and spreading of the pesticide on target biological leaf surfaces are facilitated, the effective utilization rate of the pesticide is increased, and the purpose of improving dispersity and wettability of the pesticide composition is achieved.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an insecticidal composition containing triflumefex. Background technique [0002] The chemical formula of triflurome is C 18 h 14 C l4 f 3 NO 3 , used to control the larvae of lepidopteran pests, spraying at the young larvae stage of diamondback moth, resistant to rain erosion, and does not cause phytotoxicity to crops, spinosad and ethyl spinosad have rapid contact and gastric damage to pests Toxic effect, strong penetrating effect on leaves, can kill pests under the epidermis, long residual period, has ovicidal effect on some pests, can effectively control Lepidoptera, Diptera and Thysanoptera pests, and also It can effectively prevent and control certain pests that feed on leaves in large quantities in Coleoptera and Orthoptera. It is relatively safe to predatory natural enemies and has no phytotoxicity to plants. It is suitable for use on vegetables, fruit trees, gardening, and...
