Problems solved by technology

[0002] At present, most of the pesticides used by people in agricultural production and daily life are chemically synthesized. While killing pests, they also damage beneficial insects and also affect humans. Some pesticides remain in food, vegetables, fruits and soil for a long time Among them, polluting the environment, destroying the ecological balance, causing great losses, and causing environmental damage in production, some people use emulsifiable concentrate as agricultural pesticides, and emulsifiable concentrate is formulated with organic solvents, of which organic solvents pollute environment, destroying the ecological balance, and increasing the risk of phytotoxicity
Ginkgo biloba and ginkgolic acid are the extracts of Ginkgo biloba berry skin. Ginkgolic acid is used as a plant-derived insecticide and fungicide. The product is stable to heat, cold conditions and weakly acidic pesticides. It is insoluble in water and methanol, and soluble in aromatic hydrocarbons. Solvent, used to prevent and control cotton aphids, rice borers and kill bacteria. Ginkgolic acid has not been reported as a microemulsion at home and abroad. In order to reduce the pressure of insecticides on the environment and ecology and reduce the risk of phytotoxicity, try to use Microemulsions as Agricultural Pesticides

Embodiment Construction

[0004] The substantive content of the present invention will be described in further detail below in conjunction with the embodiments.

[0005] This ginkgolic acid microemulsion is made by mixing ginkgolic acid stock solution, solvent, co-surfactant and surfactant, stirring evenly, then adding tap water, and stirring again. The ginkgolic acid stock solution is 18% extracted from ginkgo peel Ginkgolic acid stock solution, the surfactant includes three components of 6% alkylphenol polyoxyethylene ether, 14% calcium lauryl sulfate and 1.2% fatty acid polyoxyethylene ether, and the co-surfactant is 12% isopropanol and 8 % methanol, the solvent is 5% xylene, and tap water is added to 100%. Ginkgo biloba and ginkgolic acid are the extracts from the skin of Ginkgo biloba, a plant of the Ginkgo family. There is no manufacturer registration in my country for agricultural pesticides. As a botanical insecticide and fungicide, the product is stable to hot and cold conditions and weakly a...

Abstract

The invention relates to an agricultural insecticide, particularly relates to gingkolic-acid microemulsion for botanical insecticide and bactericide. The gingkolic-acid microemulsion is made of gingkolic-acid stock solution, solvent, cosurfactant and surfactant mixed and agitated evenly, and then added with tap-water and then agitated again. The invention has the advantages of reasonable formulation, stable physical and chemical performances, easy operation of production, remarkable effect of insect disinfestations; the insecticide can be used to prevent and kill cotton aphid, rice borer, Prodenialitura Fabr. and other major plant diseases and insects, and has eminent effect in inhibiting the sprout of the spores of potato late blight.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to a ginkgolic acid microemulsion of a botanical insecticide and fungicide.
