A Complete Analysis of Common Disease Prevention and Control Methods for the Shaggy Mane Mushroom
The shaggy mane mushroom, whose scientific name is Coprinus comatus, is named the "chicken leg mushroom" because its shape resembles a chicken leg and its flesh resembles shredded chicken. It is rich in nutrients, delicious in taste, and extremely high in nutritional value. The shaggy mane mushroom has strong adaptability, and coupled with its sustained economic benefits, it has attracted many people to cultivate it. However, during cultivation, diseases are the main factor endangering shaggy mane mushroom production. Now let's take a look together with the editor at the prevention and control methods for common diseases of the shaggy mane mushroom.
1. Chicken-claw fungus
Chicken-claw fungus is a parasitic pathogenic fungus that causes relatively serious harm. It mainly occurs during the fruiting body formation and growth stages of the shaggy mane mushroom, and is named for its fruiting body, which closely resembles a chicken claw. When the shaggy mane mushroom mycelium is growing, it is invaded by pathogenic mycelium in the soil, and the two grow together, producing chicken-claw mushrooms. When it occurs, the chicken-claw fungus is dark brown and connected to the base of the shaggy mane mushroom. Its mycelium competes with the shaggy mane mushroom for nutrients and will transplant the shaggy mane mushroom's growth, causing severe yield reduction or even total crop failure. It generally occurs in dark, damp environments with poor ventilation.
Prevention and control methods: Select high-quality spawn, and the culture material must be dry, fresh, and free of mildew. A low-concentration carbendazim solution can be added to the culture material to inhibit the growth of miscellaneous fungi. Once chicken-claw fungus is found, it should be dug out promptly to prevent the pathogen from continuing to spread, and drug treatment should be properly carried out at the infected site.
2. Rot disease
Rot disease is a common bacterial disease that mainly harms the fruiting body. When it occurs in the early stage of fruiting body formation, the fruiting body turns brown, and later the cap turns black and rots, leaving only the stipe. This disease is easily triggered in environments with high temperature and high humidity and poor ventilation. In addition, off-season cultivation in summer is also prone to infection by this disease.
Prevention and control methods: Before cultivation, thoroughly disinfect and sterilize the mushroom shed with limewater, bleaching powder, or Jinxing disinfectant, and properly control the air humidity and the water content of the casing soil. When the disease occurs, agricultural streptomycin can be used for prevention and control, and diseased mushrooms should be promptly removed to avoid infecting other mushrooms.
3. Brown spot disease
Brown spot disease mainly harms the surface tissue of the fruiting body and does not penetrate deep into the mushroom flesh. When it occurs, brown lesions appear on the cap or stipe of the fruiting body. As the disease progresses, they gradually expand, and finally the entire fruiting body turns brown. In humid environments, the mushroom surface has mucus. This disease is easily induced in high-humidity environments or when contaminated water is sprayed during fruiting body formation. Off-season cultivation in summer is also prone to inducing this disease.
Prevention and control methods: During mushroom emergence, control the water content of the casing soil, preferably so that the soil does not stick to the hands and the surface soil shows white. When air humidity is relatively high, strengthen ventilation to reduce humidity. During mushroom emergence, avoid spraying water onto the fruiting bodies. After diseased mushrooms are found, remove them promptly, take them out of the mushroom house for pollution-free treatment, and spray chemical agents for prevention and control.
