Abstract

The invention relates to biogenic controlled-release sterilization liquid and a preparation method and application thereof, belonging to the technical field of biopesticides. The biogenic controlled-release sterilization liquid is characterized by taking methyl alcohol as a solvent, wherein per kilogram of methyl alcohol contains the following active ingredients: 160-280g of sinomenine, 50-170g of kaempferol, 70-180g of astragalin, and 100-240g of gentiopicroside, and also contains 70-230g of penetrant, and 100-300g of controlled-release additive. The biogenic controlled-release sterilization liquid takes natural substances in a plant as the active ingredients, can control the release rate of pesticide by the pesticide release rate of the controlled-release agent, can resist bacteria continuously and efficiently, can reduce photolysis and losses of active substances in environment, avoids peak valley fluctuation of pesticide concentration, enables the pesticide to play a role smoothly and continuously so as to reduce the dosage of the pesticide and prolong the effective duration. The biogenic controlled-release sterilization liquid has the advantages of being convenient to manufacture, low in cost, stable and efficient.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, in particular to a biological source slow-release sterilizing liquid and its preparation method and application. Background technique [0002] As crop diseases become more and more serious and new diseases emerge, the amount of fungicides is increasing year by year, and the proportion of the three major types of pesticides is gradually increasing. The market prospect is broad and the development situation is attracting more and more attention. According to the statistics of the National Bureau of Statistics in 2011, the total output of pesticides in my country reached 2.648 million tons, of which the output of fungicide technical materials was 152,000 tons, a year-on-year increase of 1.3%, accounting for 5.7% of the total output of pesticides. [0003] Cao Chengyu, deputy secretary-general of the China Pesticide Industry Association, said that my country's fungicide technical manufa...
