Insecticide composition and its processing method

Abstract

The invention relates to a composition of pesticide and the manufacturing method, belonging to technical field of botanical pesticide and the manufacturing method, which is characterized in that the composition comprises an active constituent with 0.1 to 2.0 percent of the total weight. The constituent is single compound or the mixture of compounds which accords to the general formula I, wherein,the general formula I is that R1 is Na and R2 is H or OH. The composition of pesticide adopts the ring opening camptothecin salt as the insecticidal active compound, wherein, thecamptothecin salt is high in activity and can be dissolved in the water. The method in the invention has the advantages of simplifying the manufacturing method, lowering the manufacture cost of pesticide and reducing the environmental pollution by removing the organic solvent. The composition of pesticide obtained can not only kill the rice fulgorid, the plant louse, the Chilo suppressalis, the whitefly, the tea leafhopper, the diamondback moth and the cabbage caterpillar, but also provide the nutritional ingredient for the plant by sylvite and amine salt to accelerate the growth of the plant. The invention also has the advantages of safe use and good reliability.

Description

technical field The invention belongs to the technical field of botanical pesticides and manufacturing methods thereof, and specifically relates to an insecticide composition and a processing method thereof. Background technique Camptothecin (CPT) is a natural cytotoxic alkaloid, which was first isolated from the bark and bark of Camptotheca acuminata introduced from my country by Wall et al. in 1966. Studies have found that camptothecin and its derivatives have insecticidal activity, but because camptothecin and its derivatives are insoluble in water and difficult to dissolve in other common solvents for pesticides, their extraction and manufacturing costs are very high as insecticides. Difficult to industrialized production. Contents of the invention In view of the above-mentioned problems existing in the prior art, the object of the present invention is to design and provide a technical scheme of an insecticide composition and its processing method, which has simple p...
