What are the control methods for mushroom wilt disease?
Also known as dead-wither disease, it is a physiological disease. It mainly harms button mushrooms, oyster mushrooms, Phoenix mushrooms, Lingzhi mushrooms, and nameko mushrooms. Its main characteristics are: after the mushroom buds form, fruiting bodies of various sizes can all develop this disease. After onset, growth stops, they turn yellow, gradually shrivel, soften, and dry out, and finally die or rot.
Cause: The occurrence of this disease is the result of physiological obstruction. The main causes are that after primordia form, the substrate becomes too dry, causing the mushroom buds to wither; or fruiting is too dense, so nutrient supply cannot keep up, causing some small mushrooms to die; or the mushroom house temperature is too high, humidity is too high, ventilation is poor, and oxygen is lacking, causing the carbon dioxide content in the air to become too high; and also careless knocking against small mushroom buds during harvesting, or excessive fruiting, causing phytotoxicity.
Control measures: When fruiting bodies begin to wither, first determine the cause of the disease and take corresponding measures. Never spray pesticides inside the mushroom house after fruiting, otherwise phytotoxicity is likely to occur. Especially for oyster mushrooms and Phoenix mushrooms, dichlorvos must absolutely not be sprayed during the fruiting period.
