The main causes are improper management during the low-temperature season. During the low-temperature season, the humidity inside the mushroom shed may be too high, with excessive watering, and too much free water adhering to the mushroom bodies. After absorbing water, it cannot evaporate, which weakens the metabolism of the mushroom bodies, causing various pathogens to take advantage of the opportunity, multiply in large numbers, and trigger various diseases of the fruiting bodies; continuous low-temperature weather causes the temperature inside the mushroom shed to be too low, and the edible fungus fruiting bodies remain in a poor living environment for a long time, leading to disease; some edible fungus varieties are at the 3rd to 4th flush during the fruiting period, and the nutrient supply in the fungus bags is insufficient. After budding, the

The main causes are improper management during the low-temperature season. During the low-temperature season, the humidity inside the mushroom shed may be too high, with excessive watering, and too much free water adhering to the mushroom bodies. After absorbing water, it cannot evaporate, which weakens the metabolism of the mushroom bodies, causing various pathogens to take advantage of the opportunity, multiply in large numbers, and trigger various diseases of the fruiting bodies; continuous low-temperature weather causes the temperature inside the mushroom shed to be too low, and the edible fungus fruiting bodies remain in a poor living environment for a long time, leading to disease; some edible fungus varieties are at the 3rd to 4th flush during the fruiting period, and the nutrient supply in the fungus bags is insufficient. The fruiting bodies after budding cannot receive sufficient nutrient supply, resulting in yellowing and death.

For prevention and control: First, various fungicides should be frequently sprayed in the fruiting shed, such as Junjuesha, Xijunsha, Mogu Qubingwang, Kemieling, etc., generally once a week; Second, when the temperature in the mushroom shed is too low, watering should not be excessive, and the humidity should be sufficient to ensure normal growth of the fruiting bodies; Third, try to increase the temperature in the mushroom shed. For example, in oyster mushroom cultivation, the shed temperature during the day should preferably be above 15°C; Fourth, correctly understand the temperature type and normal growth temperature of various varieties, so as to have a clear target in management and manage correctly; Fifth, various disease-resistant and yield-increasing agents should be frequently sprayed on the mushroom bodies, such as Gufeng No. 1, Guangda Junwang, Lixin Junwang, Sanwei Yingyangjing, Guweishi, Guduosheng, etc.; Sixth, once disease occurs, comprehensive prevention and control can be carried out by spraying Xijunsha, Junjuesha, Mogu Qubingwang, Guweishi, Guangda Junwang, Lixin Junwang, etc.
