Problems solved by technology

Any pesticide must be made into preparations, and emodin methyl ether can only be dissolved in organic solvents such as benzene, chloroform and toluene, and is difficult to dissolve in water, methanol and ethanol, which brings certain difficulties to the production of water-based preparations
And make emulsifiable oil product, because toluene and xylene wherein are polluting chemical raw materials again, cause the secondary pollution when using farmland, vegetable field, fruit tree etc., have lost the characteristics of its green, pollution-free botanical pesticide, become a harmful agent

Abstract

The invention provides a physcion soluble granule which comprises the following compositions by weight percent: 1-10% of physcion, 10-20% of auxiliary materials, 15-30% of surfactant, 25-50% of packing and 1-2% of penetrant. A preparation method of the granule comprises the following steps: mixing the physcion and beta-cyclodextrin in proportion, then grinding the mixture to obtain a pasty mixture of physcion and beta-cyclodextrin; drying the mixture to obtain a parent drug; mixing the parent drug with the surfactant, the packing and the penetrant, and pelleting to obtain the product. By using the process technology in the invention, the original drug molecules are placed into the large cavity of beta-cyclodextrin for embedding, and can be mutually dissolved with water. By using the granule, the active ingredients are effectively embedded, the decomposition of the active substances is prevented and the quality guarantee period of the product is prolonged.

Description

technical field [0001] The invention relates to an emodin methyl ether soluble granule for preventing and controlling plant diseases and insect pests, and the preparation and application of the soluble granule. Background technique [0002] Emodin methyl ether is the active ingredient extracted from Polygonaceae Polygonum cuspidatum and rhubarb. Because it comes from natural substances, it is a real pollution-free plant-derived biopesticide, which is necessary for green agriculture and organic agriculture. It has low residue, high efficiency and Low toxicity product. Emodin methyl ether technical extraction and some preparations have obtained the organic certification of international standards. Studies have shown that this substance has good activity against plant pathogenic fungi such as cucumber powdery mildew, rice blast, cucumber gray mold, and wheat powdery mildew. It is reported that emodin methyl ether can effectively prevent cucumber powdery mildew, rice blast fung...
