Problems solved by technology

[0003] In recent years, although some good botanical pesticides have been developed and produced in my country, the progress has been slow due to limited technology and experimental means.
The effect of these pesticides on crop diseases and insect pests is slow, and the quick effect is not strong, which limits their popularization and use

Abstract

The invention relates to plant alkaloid compound microemulsion and a preparation method of the plant alkaloid compound microemulsion. The plant alkaloid compound microemulsion is characterized by consisting of the following ingredients in percentage by volume: 8 percent to 12 percent of alkaloid, 12 percent to 18 percent of emulsifying agents, 18 percent to 22 percent of cosolvents and the balance solvents, wherein the alkaloid is total alkaloid prepared from 1.5 to 2.5 weight parts of brunnera and 0.5 to 1.5 weight parts of sophora alopecuroide through ethanol and chloroform extraction, the emulsifying agents are tween-80, the cosolvents are glycol, and the solvents are ethanol with the volume percentage being 75 to 95 percent. The plant alkaloid compound microemulsion disclosed by the invention is compounded by the brunnera and the sophora alopecuroide, the synergia effect among active ingredients is utilized, the medicine effect and the integral prevention and treatment effect of products are improved, the duration is long, low toxicity and environment protection are realized, and the resistance cannot be easily generated in the use process.

Description

Technical field [0001] The invention relates to a plant alkaloid compound microemulsion and a preparation method thereof. Background technique [0002] Chemical pesticides are still the main force in the domestic and foreign pesticide market due to their fast-acting properties and effective killing of pests. However, the "3R" and "three causes" caused by them have seriously polluted the environment and agricultural products, and are harmful to human health. This has caused great harm, which is not conducive to the sustainable development of green agriculture, and even worse to the export of agricultural products. Therefore, the use of high-efficiency and low-toxicity pollution-free plant-derived pesticides to replace chemical pesticides will inevitably become the focus of the development of new pesticides. [0003] In recent years, although my country has developed and produced some better plant-derived pesticides, the progress has been slow due to limited technology and experimen...
