Biological pesticide and preparation method thereof

Abstract

The invention relates to a biological pesticide and a preparation method thereof. A raw material of the biological pesticide is an extract from mulberry leaf water, namely total alkaloids from folium mori. The method for preparing the biological pesticide comprises the steps of: cutting mulberry leaves into thin bar shapes with the width of about 2mm, adding water into the mulberry leaves in a solid-liquid mass ratio of 1: 10, performing ultrasonic treatment on the mixture for 1 hour, then boiling the mixture until the content of the mulberry leaves is about 1g / ml, and filtering the obtained solution to obtain a finished product. The invention provides a biological pesticide with no toxicity, no harm, simple preparation technology, and easy popularization and application, and the preparation method thereof.

Description

technical field [0001] The present invention relates to novel pesticide and its preparation method. Background technique [0002] As a large agricultural country, China's production and export of agricultural products occupy an important proportion in the national economy. In order to ensure the smooth growth of crops and prevent pests, pesticides are used to kill and repel insects during the growth of crops. However, in agriculture Highly toxic and high-residue pesticides are still used in production. The pesticide residues in vegetables, fruits, tea and food crops exceed the standard, causing food poisoning incidents frequently. After China's accession to the WTO, the European Union, Japan and other countries have raised the standards for pesticide residues on my country's agricultural products, greatly restricting the export of China's agricultural products. The emergence of biopesticides can greatly alleviate the problem of pesticide poisoning, but the current biopestic...

AI Technical Summary

Problems solved by technology

The emergence of biopesticides can greatly alleviate the problem of pesticides containing toxicity, but the current biopesticides have the following problems, preparation is difficult, and product quality is unstable

The active ingredients of many biopesticides are living microorganisms. Due to the high technical requirements for the formulation of their products, and the backward formulation and production technology of biological agents in my country, the physical and chemical indicators, stability, and content of active ingredients between different batches of the products are still low. Cannot meet the requirements of commercialization, resulting in the formulation of live microbial pesticides to become a bottleneck in the development of biopesticides in my country
