Control of mushroom powdery mildew
Powdery mildew is caused by Monosporium roseum infection and is transmitted by soil cover, airflow and water. It occurs seriously under the condition that the culture material is wet. The symptoms are white villous hyphae at the beginning of the cap, followed by pink powder mold. When the disease is serious, the red powder mold is very thick, the fungal folds are red and pink, and the mushroom body is stiff and dry.
Prevention and control measures: strengthen ventilation and control the water content of soil cover and culture materials. Spray 500-fold carbendazim solution and 800-fold topiramate solution in the ward.

Prevention and treatment of non-growth of mushroom hyphae
After sowing for about 10 days, the mushroom hyphae can obviously grow into the material, if not, it is because the culture material is wet and thick, the material is dry, the material layer is hardened and so on. It is necessary to find out the cause in time to create good conditions for mycelium growth. Although the material surface is dry, do not spray water on the bed when cultivating mycelium. If the material is too dry, replenish the nutritious water in the material, use 0.9 kg of soybeans per 100 square meters, about 90 kg of frothing juice, add 45 tablets of yeast, 127 tablets of vitamin B127, and 0 sugar.

The mycelium does not grow into the overlying soil layer, mainly because the soil is not properly treated, such as dry, wet, over-acid, over-alkali, the soil itself contains harmful substances, or improper soil disinfection causes drug damage. Prevention and control methods: if the soil is too dry and wet, the moisture should be adjusted in time, and ventilation should be mastered; if the soil is too acid or alkali, the pH value should be adjusted in time; if the soil itself contains harmful substances and has caused drug damage, the soil should be changed again.
