Ginkgolic acid microemulsion

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. Background technique [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 plan...

[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
