Soybean Phytophthora root rot control biological seed coating agent and its preparation method and use method

Abstract

A biological seed coating agent for preventing and controlling soybean Phytophthora root rot and its preparation method and application method. It belongs to the field of agricultural biotechnology. The seed coating agent consists of 20% Streptomyces M1-4 bacterial agent of Lake Duolun, 10% plant activator, 5% bioregulator, 10% nutrient element solution, 10% auxiliary agent, and the rest by mass percentage. The amount is composed of water. Add 1% sodium carboxymethylcellulose and 10% polyvinyl alcohol into water, heat to 80°C, stir for 20 minutes until the film-forming agent is completely dissolved, then add 0.4% rhodamine B, 3% Glycerol, 0.5% Pingping plus O-25; then add 20% Actinomycetes Streptomyces M1-4 bacterial agent, 5% bioregulator to the auxiliary agent according to the mass percentage of each component in the seed coating agent , 10% nutrient element solution, 10% plant activator and the rest of water. The seed coating agent has a significant inhibitory effect on soybean diseases and insect pests, and at the same time can increase the root-to-shoot ratio, increase the stress resistance of soybeans, and improve the quality and yield of soybeans.

Description

technical field [0001] The invention belongs to the technical field of agricultural biology, and in particular relates to a biological seed coating agent for preventing and controlling soybean Phytophthora root rot and its preparation method and application method. Background technique [0002] The start of seed coating technology was in the 1930s. The British Germain Seed Company successfully developed a seed coating agent for the first time on crops. In the early 1980s, the Soviet Union developed a combination of polymer aggregate adhesive and plant growth regulator. The finished seed coating agent, and the technology of seed coating agent has developed by leaps and bounds. At present, the seed coating technology and degree of the developed agricultural countries in the world are very high, including corn, rice, wheat, soybean, millet, vegetables, cotton, peanuts, vegetables and so on. [0003] The research and application of seed coating agents in China has developed rap...

Problems solved by technology

These chemical seed coating products generally have single ingredients, or one-sided functions, or are highly toxic, and there are certain risks and hazards during use.

Although a small amount of biological seed coating agents have appeared on the market at present, which has solved the problem of residual toxicity of seed coating agents, the effect on disease and insect control is not significant
