Abstract

The invention provides a microcapsule suspension-suspending agent containing lambda-cyhalothrin and clothianidin, which is obtained by compounding the following components in percentage by weight: 10%-85% of neonicotinoid insecticides, 1%-12% of lambda-cyhalothrin and 1%-12% of a synergistic assistant. According to the invention, a new generation of neonicotinoid insecticides, namely clothianidinand cyhalothrin, are compounded, so that the preparation process of the microcapsule is milder and easier to control, and the requirement of continuous industrial production can be met.

Description

technical field [0001] The invention relates to an insecticide, in particular to a microcapsule suspension-suspension agent containing efficient cyhalothrin and clothianidin and a preparation method thereof. Background technique [0002] Vector-borne diseases, including malaria, dengue and leishmaniasis cause very high morbidity and mortality in tropical countries. For the control of vector-borne diseases, vector control methods, such as long-lasting insecticidal nets (LLINs), indoor residual spraying (IRS), and management of larval sources, are typically the most effective interventions. Vector control has historically been important for the control and elimination of many arbovirus-borne diseases, including malaria, onchocerciasis, leishmaniasis, Chagas disease, and Aedes-borne diseases. Widespread LLINs and IRS in sub-Saharan Africa significantly reduced malaria infection rates by more than 50%. Although these programs have been successful in reducing vector-borne disea...
