Problems solved by technology

[0008] 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 of materials are limited

Abstract

The invention relates to a chlorfenapyr and matrine-containing insecticidal composition and application thereof. The composition consists of a chlorfenapyr and matrine pesticide serving as a main active ingredient, an auxiliary agent and an excipient and is prepared into microemulsion, emulsion in water, a suspending agent, water dispersing granules and emulsifiable solution, wherein the mass ratio of the chlorfenapyr to the matrine in the pesticide is 300:1-10:1, preferably 49:1-29:1. The insecticidal composition has strong synergistic action, prevents the medicament resistance of pests, prolongs the service life of pesticide types, reduces pesticide residues and can solve the problem of insufficient raw materials of the matrine. The insecticidal composition can prevent and control the pests such as lepidoptera, coleoptera, homoptera, thysanoptera and deptera pests and harmful mites, and particularly can be used for preventing and controlling plutella xylostella, prodenia litura, phyllotreta striolata, rice planthopper, trialeurodes vaporariorum, aphids, thrips palmi karny, gall midge and phytophagous mites.

Description

technical field [0001] The present invention relates to an insecticidal composition and its application. 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, it is a better choice to study the compounding of chemical pesticides and biological pesticides, which is of great significance for the protection of people's health and the sustainable development of agriculture. [0003] Chlorfenapyr (Chlorfenapyr), molecular formula: C 15 h 11 BrClF 3 N 2 O, Molecular Weight: 407.6169, CAS No.: 122453-73-0, Alias: Chromfenapyr. [0004] Chlorfenapyr action characteristics: The drug is a new type of pyrrole compound, acting on the mitochondria of cells in insec...
