Detailed Explanation of Prevention and Control of Mushroom Wilt Disease and Fertilization Methods

I. Symptoms The wilt pathogen mainly infects the mushroom stipe; after the stipe is infected, it shrinks and turns brown, so the fruiting body stops growing and eventually becomes a rigid mushroom. The pathogen can also secrete a toxin that kills the mushroom mycelium and pins.

II. Occurrence Characteristics This disease is mainly caused by pathogen-carrying casing soil.

III. Prevention and Control Methods (1) Casing soil disinfection. Sterilize the casing soil with steam at 70°C. (2) The casing soil layer should not be too thick, and ventilation in the mushroom house should be strengthened. (3) Spray a 500-fold solution of thiophanate or carbendazim on the affected parts for control.
