The invention relates to a pueraria peduncularis extract and osthole insecticidal composition for preventing agricultural pests, the weight ratio of active components of pueraria peduncularis extract to osthole in the insecticidal composition is 1:3 to 3:1, and further the insecticidal composition is prepared into microemulsion. Compared with a single agent, the insecticidal composition has the advantages of broad insecticidal spectrum and synergistic effect, can effectively reduce use cost, reduces pest resistance to insecticides, and can effectively prevent the diamondback moth, cabbage caterpillar, corn armyworm, tea geometrid, empoasca flavescens and other agricultural pests.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to a combination of agents for preventing and controlling agricultural pests, more particularly to preparing the combination of agents into a microemulsion for use in diamondback moth, cabbage caterpillar, corn armyworm, tea looper, small green leafhopper, etc. Control of agricultural pests. [0002] technical background [0003] my country is a large agricultural country, and the healthy and sustainable development of agriculture is of great significance to my country's economic and social stability. However, the increasingly rampant agricultural pests endanger the growth and development of crops in agricultural production, affect the quality and yield of agricultural products, and in severe cases can lead to crop failure and cause losses to farmers. It has become an important bottleneck restricting agricultural development. [0004] The prevention and control methods of agricult...
