Abstract

Provided are a bavachalcone soluble concentrate and a preparing method and application thereof. The bavachalcone soluble concentrate relates to an agricultural soluble concentrate and is composed of raw materials according to weight percentage: 0.01-5% of bavachalcone, 8-20% of emulsifiers and solvents which complement the solution to be 100%. The preparing method of the bavachalcone soluble concentrate is that pure bavachalcone or bavachalcone plant extracts are mixed with the solvents, dissolved, added with the emulsifiers, stirred and uniformized, the insufficient portion is complemented by the solvents to be 100%, and the 100% solution stands for 4-5 hours. The bavachalcone soluble concentrate is used for preventing plant fungus diseases such as rice blast, apple rotting, cucumber anthracnose, tomato late blight, hot pepper anthracnose, cucumber gray mold and rice sheath blight disease or plant viruses such as tomato mosaic virus, soybean mosaic virus, tobacco mosaic virus and tobacco and potato Y virus. The bavachalcone soluble concentrate has good mutual solubility with water, and accordingly the sterilizing effect in practical application is greatly improved and the bavachalcone soluble concentrate is stable in active constituent content.

Description

technical field [0001] The invention relates to an agricultural soluble liquid, in particular to a psoraleachalcone soluble liquid, a preparation method thereof and an application in preventing and treating plant diseases. Background technique [0002] Pesticides play a very important role in agricultural production. With the improvement of people's health awareness, most countries attach great importance to the safety of agricultural products, and the restrictions on pesticide residues are very strict. In order to improve the competitiveness of my country's agricultural products in the international market and reduce pesticide residues, efforts to develop new biopesticides have become a top priority. Botanical pesticides come from nature, do not pollute the environment and agricultural products, are relatively safe to humans and livestock, are not prone to drug resistance, low toxicity, and low residue. Therefore, botanical pesticides have broad market prospects. [0003]...
