Problems solved by technology

However, in the existing plant-derived biopesticides, the active substances contained are relatively single, the complementarity is not strong, the ratio of plant-derived raw materials is not reasonable enough, and the purity (content) of the active substances in the raw materials is not high, resulting in low control efficiency of this type of biopesticides , the knockdown is slow, which affects the effect of controlling pests

Abstract

The invention discloses a 0.3% matrine compounded agent, belonging to plant source biological pesticide, characterized by using a natural plant as a main body, comprising more than five Chinese medicinal plants, prepared by technical extraction of soaking, cooking and filtering and the like. The plant source material and the weight percent are as follow: kuhseng 35-45%, oriental biter weed 10-15%, Chinaberry seed 12-18%, kusnezoff mondshood 10-15%, agrimony 8-13%, nicotiniana rustica 11-16%, also added with radix stemonae stemona 2-5%, triperygium wilfordii 2-5%, the extracts are matched with diluted emulsifying agent, with marked pest prevention effect. The invention is used as a novel highly active biological pesticide, with wide applying foreground.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to a new high-efficiency 0.3% matrine compound agent mainly composed of flavescens extract. Background technique [0002] For a long time, traditional chemical pesticides have seriously threatened the sustainable development of agriculture, showing toxic and side effects on people's health, residues and "three causes" are becoming more and more obvious, and chemical pesticides are gradually being replaced by biological pesticides and low-toxicity and high-efficiency chemical pesticides . Botanical pesticides are "comprehensive control", "one drug with multiple uses", economical, safe, and relatively ideal biological pesticides, with broad prospects for development. In recent years, biopesticides extracted and formulated from natural plant sources have been continuously developed in China, and there are also reports on insecticides containing matrine. However, in the existing plant-derived...
