Problems solved by technology

But at the same time, the environmental pollution caused by chemical pesticide residues is also becoming more and more serious. Chemical pesticides enter the human and animal bodies through the food chain and cause great harm.
Moreover, the structure of chemical pesticides is single, the residual time is long, and the resistance of pests is easy to form

Abstract

A vegetable insecticide for agricultural crops is prepared from 10 Chinese-medicinal materials including xanthium fruit, ovate catalpa fruit, sophora herb, wild aconite root, etc.

Description

technical field [0001] The invention relates to a medicinal plant insecticide for crops Background technique [0002] At present, the insecticides used for crops are all chemical pesticides, and chemical pesticides have played a huge role in controlling pests and diseases and improving crop yields. But at the same time, the environmental pollution caused by chemical pesticide residues is also becoming more and more serious. Chemical pesticides enter the human and animal bodies through the food chain and cause great harm. Moreover, the structure of chemical pesticides is single, and the residual time is long, and the resistance of pests is easy to form. Existing studies have shown that cancer, cardiovascular and other diseases that seriously endanger human health are closely related to the excessive use of chemical pesticides. With the aggravation of environmental pollution, people pay more and more attention to the research work of plant pesticides. ...
