Euphorbia-one pesticide and preparing method thereof

Abstract

The wolfmelin insecticide and its preparation method are characterized in that the wolfmelin extract is cleaned, crushed, soaked in an organic solvent, repeatedly extracted, and concentrated into a liquid extract, and the extraction temperature is 30-95°C , The time is 2-10 hours; add 10-55 parts of wolfmelin extract, 0-5 parts of azadirachtin, 0-12 parts of motherwort alkaloids, and 15-55 parts of organic solvent into a mixing bowl with a stirrer and a thermometer. In the kettle, under stirring at a temperature of 40-100°C, mix for 0.5-5 hours, add 8-16 parts of surfactant, 2-30 parts of tea saponin, 0.2-2 parts of azone, 3-11 parts of stabilizer, 0.5-1.5 parts of the preservative and 0.1-0.2 parts of the pH regulator are continuously stirred and mixed evenly to obtain the lumazone insecticide product. The product has significant killing and preventing effects on various pests of vegetables, fruit trees, flowers, forest trees and field crops such as Homoptera and Spleen Acarina.

Description

1. Technical field [0001] The invention relates to a lumeminone insecticide and a preparation method thereof, belonging to the field of botanical biological agricultural chemicals. 2. Background technology [0002] my country has used the characteristics of plants, that is, to use some of its ingredients to prevent and control crop diseases and insect pests. According to records, plant pesticides, such as croton, have been used to control pests as early as 1800 years ago. Among the 1892 kinds of medicines described in the "Compendium of Materia Medica" compiled by Li Shizhen in the 24th year of Wanli in the Ming Dynasty (1596), it was mentioned that plants such as Baibu, veratrum, chamaejasma, and Sophora flavescens have insecticidal properties. [0003] It can be seen from the relevant literature review and analysis that at present, although the research on the use of Daphne chamaejasma as a biological pesticide has been reported, it is mainly a simple application. For ex...

Problems solved by technology

This technology uses crude plant extracts to form the original pesticide. Although the preparation method is cheap and the process is simple, the pesticides prepared by this technology are complex in composition, the active ingredients of the drug are difficult to detect, and the drug effect is not easy to stabilize.

More importantly, the crude extract contains substances that are highly toxic to humans and animals; the inclusions are too complex, and it is not easy to study the mechanism of action of its main insecticidal active substances, and it is not easy to study its relationship with other insecticides based on its mechanism of action. Research on the mutual cooperation of pesticides to further improve the efficacy or expand their insecticidal spectrum
