Control of soft rot of Pleurotus ostreatus
1. Fresh cottonseed hulls or corn kernels should be selected as raw materials for culture medium treatment. The mixture should be exposed to the sun for 2-3 days before mixing, or ultraviolet rays should be used to kill some of the miscellaneous bacteria in the culture. Fermentation process should be strict, complete, uniform and thorough. Can add temperature starter, Lixin bacteria Wang or Ke Mei Wang and other products to improve the ability to resist miscellaneous bacteria.
2. When cultivating large bags of mushrooms, they should be placed in cool, ventilated and clean places. Try not to cultivate in mushroom house (shed), avoid breeding a large number of miscellaneous bacteria in the process of mycelium cultivation, resulting in pollution of mushroom production place, and avoid high temperature burning bacteria, reducing the viability of mycelium.
3. Before using mushroom house treatment, it is best to expose it to the sun for a period of time or rotate it with other crops. 2-3 days before the mushroom bag is put into the mushroom house (shed), the old mushroom shed should be thoroughly cleaned and the empty shed disinfected. Available fumigants, sulfur or formaldehyde, etc.
4. Soil disinfection shall adopt raw soil from field or vegetable garden, keep away from domestic garbage and livestock farms, etc., and disinfect and bury the selected covering soil.

(1) pathogenic characteristics and harmful symptoms: pathogenic hyphae are white, aerial hyphae grow exuberantly and densely, cotton-like; conidiophores grow directly from aerial hyphae, slender and sparse; conidiophores are verticillate and apical, solitary or clustered.

Measures to Prevent Deformity of Pleurotus ostreatus
In the production process of Pleurotus ostreatus, abnormal mushroom is easy to form due to inadequate management measures and inappropriate environmental conditions. In the production, we should find out the causes of abnormal mushroom formation and take effective control measures. 1. spherical or flasks: the stalk of Pleurotus ostreatus is spherical or flasks, the surface is uneven or twisted in waves, the cap cannot be formed, only a small point or obvious icicle stripes, which are caused by virus infection. Apply virus K, virus A, disinfectant spray or smear control. II. Cauliflower shape
