Biopesticide for pest control and preparation method thereof

Abstract

The invention discloses a biopesticide for pest control and a preparation method thereof, and belongs to the technical field of biopesticides. Chinese herbal medicines such as artemisia japonica, fructus evodiae, asafoetide, Chinese wingnut bark, celastrus angulatus, thickfruit millettia seeds or fruits, artemisia rupestris and hairypetal millettia root stems and leaves are selected, and then extracted with ethanol to prepare the biopesticide. Tests show that the biopesticide can be widely applied to prevention and control of injurious insects of vegetables, fruit trees, medicinal materials, flowers, plants and grasslands, and in vitro insects of poultry and livestock, thereby being good in prevention and control effect, non-toxic to people and livestock, and pollution-free to the environment.

Description

technical field [0001] The invention belongs to the field of insecticides, in particular to a biological pesticide for preventing and controlling insect pests and a preparation method. Background technique [0002] At present, most of the insecticides in the prior art are chemical pesticides, which have low drug efficacy and long residual toxicity period, seriously affecting the crop growth environment and the health of humans and animals. According to literature reports, the utilization rate of pesticides is generally 10%, and about 90% of the remainder remains in the environment, causing environmental pollution. A large amount of pesticides volatilize into the air, flow into water bodies, settle and accumulate in the soil, pollute agricultural, livestock, fish and fruit products, and transfer to the human body through the enrichment of the food chain, causing harm to the human body. Highly effective and highly toxic pesticides are highly toxic and remain in the environmen...

AI Technical Summary

Problems solved by technology

High-efficiency and highly toxic pesticides are highly toxic and remain in the environment for a long time. When humans and animals eat food containing pesticide residues, they will cause cumulative poisoning

This type of hazard often takes a long time to accumulate before showing symptoms, and it enters the human body through the enrichment of the food chain, and it is difficult to detect in time, causing serious harm
