Abstract

The invention relates to a preparation method of a biological pesticide. The preparation method comprises the following steps that a Chinese herbal medicine extracting solution, a synergist and vegetable oil are added into a homogenizer in a certain mass ratio, homogenization is carried out at least once, and then the biological pesticide is obtained. The biological pesticide has obvious insecticidal and bacteriostatic effects. The raw materials are derived from plants, and the biological pesticide has the advantages of being low in toxicity and harmless to human bodies.

Description

technical field [0001] The invention relates to a preparation method of biological pesticide. Background technique [0002] With the improvement of living standards, people pay more and more attention to food safety issues. The long-term use of chemical pesticides has caused great damage to the ecology. Chemical pesticides are not easy to degrade, and there are pesticide residues, which seriously threaten people's health. In 2017, the "No. 1 Central Document" mentioned comprehensively improving the quality of agricultural products and food safety. Adhere to quality to promote agriculture, implement the agricultural standardization strategy, highlight high-quality, safety, and green orientation, and improve the agricultural product quality and food safety standard system. It can be seen that low-toxic pesticides that are harmless to humans and animals and do not damage the ecological environment will become the main direction of future research.
