Problems solved by technology

[0004] However, matrine plant pesticides also have some disadvantages. First, the complex structure of the compound makes it difficult to synthesize or the synthesis cost is too high; second, due to the regional distribution of matrine, there are many limiting factors in the selection of processing sites; third, The collection of Sophora flavescens is seasonal and the sources are limited

Abstract

The invention relates to a disinsection composition containing a matrine and a neonicotinoid insecticide, and application thereof. The composition mainly uses the matrine and the neonicotinoid insecticide and is prepared by an auxiliary agent and an excipient to form microemulsion, emulsion in water, suspending agent, water dispersible granule, wetting powder and missible oil, wherein the mass percentage of the matrine and the neonicotinoid insecticide is 30:1-1:100. The disinsection composition has higher synergy effect, prevents pests from becoming resistant to drugs, prolongs the service life of pesticides and reduces pesticide residue. The composition can be used for preventing and treating homoptera, lepidoptera, thysanoptera, coleopteran and diptera on crops, particular for rice planthopper, trialeurodes vaporariorum, aphid, tryporyza incertulas, chilo suppressalis, thrips, paddy weevil and gall midge.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to a compound composition containing matrine and neonicotinoid. Background technique [0002] In recent years, people pay more and more attention to the sustainable development of agricultural production and the coordinated development of human and environment. After joining the WTO, the market competition has become more intense, and green barriers have seriously restricted the export of agricultural products in our country. Therefore, the research and development of biopesticides is particularly important, and the development of biopesticides has become an important trend to ensure human health and sustainable agricultural development. [0003] Matrine (Matrine), with a molecular formula of C15H24ON2, is the main component of alkaloids obtained by extracting the roots, stems, leaves and / or fruits of Sophora flavescens through organic solvents such as ethanol. It ...
