AI Technical Summary

Technical Problem

The existing suspension agent products of Ivermectin and nitrile or spironidine ethyl ester have shortcomings in stability, spreadability, permeability and prevention and control effects, and are difficult to meet the needs of processing, storage, safety and field applications.

Method used

Isomeric alcohol polyoxyethylene ether and fatty amine polyoxyethylene ether are used as synergistic additive compositions, and a stable suspension agent system is formed through a combination of specific mass ratios (1:10-5:1) with evermectin and nitrile or spirozoite ethyl ester to improve the thermal storage stability and permeability of the preparation.

Benefits of technology

It significantly improves the dispersion stability, thermal storage stability and permeability of the Ivermectin suspension agent, enhances the control effect of harmful mites and lepidoptera pests, and ensures the safety of crops.

Abstract

The invention relates to an ivermectin suspending agent preparation and a preparation method thereof. The ivermectin suspending agent preparation comprises 1.5%-40% of effective components, 2%-10% of synergistic additive composition, 0.1%-45% of other additives and the balance of water. Wherein the effective components are ivermectin and a component M, the component M is chlorfenapyr or spirotetramat, and the mass ratio of the component M to the chlorfenapyr to the spirotetramat is 1: 1-1: 20; the synergistic additive composition is prepared from isomeric alcohol polyoxyethylene ether and fatty amine polyoxyethylene ether, and the mass ratio of the isomeric alcohol polyoxyethylene ether to the fatty amine polyoxyethylene ether is (1: 10)-(7.5: 1). Compared with the prior art, the isomeric alcohol polyoxyethylene ether suspending agent can relieve the problem that the heat storage suspension rate is reduced due to the fact that isomeric alcohol polyoxyethylene ether is added into a suspending agent preparation of ivermectin, the control effect on phytophagous mites, lepidoptera pests and the like is improved, and the actual requirements of processing, storage, safety, field application and the like are met.
