Soybean gray mold is a common fungal disease on soybeans, which seriously affects soybean yield and quality. Here are some simple and effective ways to help you deal with soybeanea.
Pathogen analysis. Soybean gray mold is mainly caused by gray mold in soybean leaves, stems and seeds, and in severe cases, it leads to yellowing of leaves, defoliation, and seed rot.
Prevention and control methods. Biocontrol.
Use of antagonistic bacteria: Appropriate antimicrobial spraying, such as Bacillus subtilis, can effectively inhibit the growth and reproduction of Botrytis cinerea.
Application of beneficial microorganisms: By applying beneficial microorganisms, such as red shell fungus, Trichoderma, etc., the number of gray molds in the soil is reduced, and the possibility of disease occurrence is reduced.
Agronomic measures. Reasonable dense planting: Properly adjust the density of soybeans and keep good ventilation, which is conducive to reducing the occurrence of diseases.
Early sowing and late harvest: avoid high temperature and rainy season, try to avoid soybean suffering from high temperature and high humidity environment, and reduce the occurrence of diseases.
Chemical control. Spraying fungicides: Preventive spraying with effective fungicides, especially in the early stage of soybean growth and disease-prone periods, can effectively control the occurrence and spread of diseases.
Rotate the use of biocides: Regularly replace the biocides using different mechanisms to reduce the resistance of the gray mold to the fungicides.
