Abstract

The invention relates to a pesticide composition containing lightyellow sophora root and Caesalpinia crista extracts, and a preparation method and application thereof, and belongs to the field of pesticides. In order to solve technical problems, the invention provides the pesticide composition containing the lightyellow sophora root and Caesalpinia crista extracts, and the preparation method and application thereof. According to the pesticide composition containing the lightyellow sophora root and Caesalpinia crista extracts, active ingredients are extracted from 1 weight part of lightyellow sophora root and 0.2 to 4 weight parts of Caesalpinia crista; the active ingredients can be prepared by mixing the lightyellow sophora root and the Caesalpinia crista and extracting together, or prepared by separately extracting the lightyellow sophora root to obtain the lightyellow sophora root extract, separately extracting the Caesalpinia crista to obtain the Caesalpinia crista extract, and mixing the two extracts. The pesticide composition containing the lightyellow sophora root and Caesalpinia crista extracts has an obvious effect of controlling Homoptera, Acarina, Thysanoptera and Lepidoptera pests, and has positive significance for agricultural production.

Description

technical field [0001] The invention relates to a pesticide composition containing Sophora flavescens and South China yunshi extract, a preparation method and an application, and belongs to the field of pesticides. Background technique [0002] In recent years, in the field of agriculture and forestry, due to single and unscientific use of drugs, plant diseases and insect pests have developed resistance to varying degrees, while chemical pesticides are still used as the main control species in agricultural and forestry production, causing environmental pollution and ecological environment. With the improvement of people's living standards and the enhancement of health awareness, the research and development of biopesticides is gradually attracting the attention of pesticide research and development workers, and has become a hot spot for the sustainable development of agriculture and forestry. An effective way to improve drug efficacy. Among them, botanical pesticides have b...
