Abstract

The invention discloses an insecticidal composition containing azadirachtin and bifenthrin and relates to the technical field of pesticides. The composition comprises active components which are azadirachtin and bifenthrin. The mass ratio of the azadirachtin to the bifenthrin is 1:40-40:1. The composition has obvious synergistic effects when compared with single agents, can effectively control piercingsucking mouthpart pests, reduces using amounts of pesticides, saves pesticide using costs, makes up disadvantages of the single agents and tolerance of pests to the single agents, and improves insecticidal activity.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition mixed with two insecticidal active compounds, in particular to an insecticidal composition containing azadirachtin and bifenthrin and its preparation. Background technique [0002] Chemical control is an important means of preventing and controlling pests in agriculture or public health. However, the effects of currently used pesticides on certain pests are still not satisfactory; and, due to the prolonged use of pesticides, many pests have developed resistance to commonly used pesticides. Many piercing-sucking mouthpart pests are major causes of worldwide pests and diseases in the production of many types of cereals and vegetables, and their control is of great economic value. Prevention and control with conventional agents is becoming increasingly difficult. Therefore, there is an urgent need to develop new methods and drugs for controlling these pe...
