Problems solved by technology

It mainly uses the piercing-sucking mouthparts of nymphs and adults to suck plant juice, harming young leaves, young shoots and flowers and fruits. Young leaves cannot be stretched, and the damaged young shoots grow distorted, and stop growing in severe cases; harming flowers and fruits can cause fruit deformities , seriously affecting the normal growth of fruit trees and crops, resulting in reduced yield and lower quality
At present, several chemical pesticides such as cypermethrin and malathion are mainly used to control stinkbug pests in production, but malathion is sensitive to grapes and other crops

Abstract

The invention relates to a compound insecticide with environmental compatibility, high efficiency and low toxicity consisting of osthole and matrine, which is particularly used for application research of controlling green plant bugs on grapes. The weight ratio of two components, namely the osthole and the matrine in a compound complex is 4: 1-1: 4, the preferred ratio is 1: 1-1: 4, and the best ratio is 1: 2. The osthole and the matrine are compounded, and then the compound complex is applied to controlling the green plant bugs on the grapes, shows obvious synergistic effect, and has outstanding performance on the application to controlling the green plant bugs on the grapes.

Description

technical field [0001] The invention relates to a botanical insecticide, in particular to two botanical pesticides, osthole and matrine, which are compounded and used as an insecticide for preventing and treating Lygus vinifera, belonging to the technical field of insecticide compositions. Background technique [0002] For a long time, due to the extensive use of chemical pesticides in production to ensure the output and quality of agricultural products, there has been a huge pressure on the ecological environment, and some pests have rapidly developed resistance to pesticides, further increasing the amount of pesticides, resulting in the occurrence of pesticides in agricultural products. The residual amount seriously exceeds the standard, causing great harm to humans, animals and the environment. The development and utilization of environmentally compatible and harmless pesticide resources are increasingly favored by various countries. [0003] Botanical pesticides are a c...
