Symptoms: When the disease occurs, white mycelium appears on the mushroom bed and spreads quickly. If it is not controlled in time, it can be expanded to the entire mushroom bed. In the case of high humidity, the fruiting bodies can all be "phagicized" and only one group of white hyphae can be seen, and the later white mycelium becomes water red. Second, the occurrence of features: soft rot bacteria are widely found in the soil, in the cover soil or mushroom body surface colonies, and in a short period of time produce spores, these spores by the air flow, splashing when the water droplets and mushroom oozing out of the juice spread. The disease is easy to occur in case of overlying soil and low temperature. This disease often occurs in small areas in mushroom houses and is rarely widespread. Third, control methods: 1, cover soil disinfection. 2. When the disease occurs locally, the number of water sprays on the mushroom bed should be reduced, and the ventilation of the mushroom house should be strengthened to reduce the humidity. Spray 2%% to 5%% of formaldehyde solution or thiophanate-methyl 500 times solution in the affected area to prevent and cure, and sprinkle lime powder for prevention and treatment.
