Soft rot of edible fungi
Symptoms of harm: first, white bead-like hyphae appear on the surface of the bed covered with soil. if not dealt with in time, it will spread quickly and become water-red. The infection fruiting body starts from the stalk to the lid, which is immersed in water, browns and softens gradually until it decays.
Classification attribute: fungal diseases caused by Cladosporium dendriformis
Disease characteristics: covered with soil bacteria, mainly spread by air and water droplets in the mushroom house.
Prevention and treatment methods: strictly cover soil disinfection, cut off the source of the disease. When local occurrence occurs, spray 2%-5% formaldehyde solution or 800 times liquid carbendazim or 800 times liquid methyl topiramate. It can also be sprinkled with 0.4 cm thick lime powder on the surface of the hospital bed. At the same time, reduce water spraying on the bed surface, strengthen ventilation, cool down and drain moisture.

Smut of Pleurotus ostreatus, a medicinal plant
The scientific name of SagittariatrifoliaL. Commonly known as scissors grass, belongs to the family Alismatidae. The whole herb and corm are used as medicine. It has the effect of clearing heat and stopping bleeding, detoxification and detumescence. It is also a vegetable in autumn and winter. Most of them are planted in rice fields after rice harvest. It is distributed in the north and south provinces of our country. The main symptoms were damage to leaves, petioles, floral organs and bulbs. The primary yellow to orange-yellow scar spot on the leaf is slightly raised, and the posterior blister spot is withered and yellow and ruptured, scattered with small black powder grains, that is, the spore mass of the pathogen. Some diseased leaves are deformed and twisted. Leaf

Prevention of soft rot of edible fungi
Symptoms: When the disease occurs, white hyphae appear on the mushroom bed and spread rapidly. If it is not controlled in time, it can be extended to the whole mushroom bed. In the case of higher humidity, all the fruiting bodies can be "swallowed" and only a mass of white hyphae can be seen. In the later stage, the white hyphae become water red. 2. Occurrence characteristics: soft rot bacteria widely exist in soil, form colonies on the surface of soil or mushroom body, and produce spores in a short period of time. These spores spread by means of air flow, water droplets splashed when spraying water and exudation of mushroom body. Overwet and cold soil cover
