Problems solved by technology

[0003] At present, the prevention and control of soybean root rot is mainly through chemical reagent sterilization, which not only has high raw material costs, but also has a great impact on the human body and the soil environment, and is not suitable for green organic food
Although the use of disease-resistant varieties is economical and effective, long-term use of a single resistant variety will easily lead to the loss of soybean resistance to root rot; Poor, and the extraction and production process is not perfect, so the development of environmentally friendly green prevention and control technology is of great significance for disease suppression and crop safety

Abstract

The invention discloses a Chinese herbal medicine type seed coating agent and a preparation method thereof, and belongs to the technical field of preparation of seed coating agents. In order to solve the technical problem about prevention and control of soybean root rot, the invention provides a Chinese herbal medicine type seed coating agent, which is prepared by mixing the following raw materials by weight percent: 20-30% of fructus cnidii extract, 15-25% of rhizoma anemarrhenae extract, 0.4-0.5% of a wetting agent, 2.0% of a dispersing agent, 2.5% of a thickener, 1.0% of a molding agent, 5% of antifreezing agent, and the balance of water; after mixing, preparing slurry, and processing to a particle size of 35-40 mum. The seed coating agent prepared by the invention has a significant inhibitory effect on fusarium oxysporum, and can inhibit the occurrence of root rot of soybean and other crops, reduce and replace the use of traditional chemical pesticides, reduce the cost, and reduce the environmental pollution of chemical pesticides, and significantly reduce the incidence of soybean root rot.

Description

technical field [0001] The invention belongs to the technical field of preparation of seed coating agents, and in particular relates to a Chinese herbal medicine type seed coating agent and a preparation method thereof. Background technique [0002] Soybean root rot is a common disease, and it is mainly distributed in the northeast soybean production area and the Huanghuai area in China. The disease causes serious damage to soybean seedlings in a soil-borne manner, generally reducing yield by 10% to 30%, and reducing yield by more than 60% or even extinction in severe disasters. There are many types of soybean root rot pathogens and it is difficult to control them. Fusarium oxysporum is the dominant strain in Heilongjiang reclamation area. In addition, Fusarium oxysporum can cause root rot of apples, grapes, peppers, zucchini, alfalfa and Chinese herbal medicines and other crops. Inhibition of Fusarium oxysporum will be of great significance to the control of soybean and ot...
