Abstract

The invention relates to a preparation method of a Chinese herbal insecticide. The method adopts the making steps of crushing, purification and the like. The preparation method provided by the invention is simple, low in cost, and can effectively preserve and give play to the pest killing performance of the raw materials. The Chinese herbal insecticide prepared by the method provided by the invention has significant pest killing effect, does not generate resistance in pests easily, also can be naturally degraded, and has good environmental compatibility, therefore avoids pesticide residue of agricultural products, and is safe to the natural ecological environment and free of pollution.

Description

Technical field [0001] The invention relates to a preparation method of an insecticide, in particular to a preparation method of a Chinese herbal medicine insecticide, and belongs to the technical field of pesticides. Background technique [0002] Because of the natural pest disasters, people spray pesticides when planting crops. Some of the pesticides currently in use can be biodegraded into harmless substances in a relatively short period of time, while organochlorine pesticides including DDT are difficult to degrade and are pesticides with strong residues. According to the characteristics of the residues, the residual pesticides can be divided into three types: the pesticides that are easy to remain in the plant body are called plant residual pesticides; the pesticides that are easy to remain in the soil are called soil residual pesticides. Insecticides, and the pesticides that remain in the water for a long time are called water residual pesticides. There are two forms of r...
