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
The present invention relates to a kind of agricultural insecticide, particularly a kind of vegetable source pesticide bactericide ginkgolic acid microemulsion.
Background technology
At present, people are in agricultural production and daily life, used insecticide is chemosynthesis mostly, in kill pests, beneficial insect also there is infringement, also influential to the mankind simultaneously, some agricultural chemicals remains in grain, vegetables, fruit and the soil for a long time, contaminated environment is destroyed the ecological balance, causes great loss, and can produce the murder by poisoning that impairs environment aborning, have human missible oil to make agricultural insecticide, and missible oil is formulated with organic solvent, wherein the organic solvent contaminated environment, destroy the ecological balance, and increase poisoning danger.Ginkgol, ginkgoic acid are the sarcotestal extracts of Ginkgoaceae plant Ginkgo biloba, ginkgolic acid is as the vegetable source pesticide bactericide, product is stable to heat, cool condition and faintly acid agricultural chemicals, be insoluble in water, methyl alcohol, be dissolved in aromatic hydrocarbon solvent, be used to prevent and treat cotten aphid, rice borer and kill bacillus, ginkgolic acid is not seen the report that microemulsion is arranged at home and abroad as yet, in order to alleviate pressure and the reduction poisoning danger of insecticide, attempt with ginkgolic acid microemulsion as agricultural insecticide to environmental ecology.
Summary of the invention
The object of the present invention is to provide a kind of ginkgolic acid microemulsion.This ginkgolic acid microemulsion is to be mixed by ginkgolic acid stoste, solvent, cosurfactant and surfactant, stir, add running water again, stir again and form, ginkgolic acid stoste is by the 10-40% ginkgolic acid stoste of extracting in the ginkgo pericarp, surfactant comprises 2-12% alkylphenol polyoxyethylene, 6-20% dodecyl sulphate calcium and three kinds of compositions of 0.3-2.2% aliphatic acid polyethenoxy ether, cosurfactant is 6-20% isopropyl alcohol and 2-13% methyl alcohol, solvent is a 3-15% dimethylbenzene, and running water is added to 100%; For reaching better effect, ginkgolic acid stoste is by the 15-26% ginkgolic acid stoste of extracting in the ginkgo pericarp, surfactant is 3-8% alkylphenol polyoxyethylene, 9-15% dodecyl sulphate calcium and three kinds of compositions of 0.5-1.5% aliphatic acid polyethenoxy ether, cosurfactant is 9-15% isopropyl alcohol and 5-10% methyl alcohol, and solvent is a 3-8% dimethylbenzene.The present invention has following beneficial effect: prescription rationally, physicochemical property is stable, and production operation is easy, has significant insecticidal effect, be used to prevent and treat staple crops damage by disease and insect such as cotten aphid, rice borer, prodenia litura, the spore of potato late blight is had obvious suppression germination effect.
Embodiment
Below in conjunction with embodiment essentiality content of the present invention is described in further detail.
This ginkgolic acid microemulsion is mixed by ginkgolic acid stoste, solvent, cosurfactant and surfactant, stir, add running water again, stir again and form, ginkgolic acid stoste is by the 18% ginkgolic acid stoste of extracting in the ginkgo pericarp, surfactant comprises 6% alkylphenol polyoxyethylene, 14% dodecyl sulphate calcium and three kinds of compositions of 1.2% aliphatic acid polyethenoxy ether, cosurfactant is 12% isopropyl alcohol and 8% methyl alcohol, solvent is 5% dimethylbenzene, and running water is added to 100%.Ginkgol, ginkgoic acid are the sarcotestal extracts of Ginkgoaceae plant Ginkgo biloba, and China does not also have producer's registration aspect agricultural insecticide.Ginkgolic acid is as the vegetable source pesticide bactericide, and product is stable to heat, cool condition and faintly acid agricultural chemicals, is insoluble in water, methyl alcohol, is dissolved in aromatic hydrocarbon solvent, is used to prevent and treat cotten aphid, rice borer and kills bacillus.Along with the day by day strictness of sustainable economic development to environmental protection, environment friendly agricultural more and more comes into one's own, and ginkgolic acid has positive meaning as botanical pesticide to the use that reduces chemical pesticide.
