What are the diseases and insect pests of mushrooms
1. The main type of disease spot is brown spot, and there are white hairy hyphae on the surface of fruiting body and small brown spots at the same time. Affected by it, the top cover of mushroom shrinks and individual mushroom cover is dry and cracked; others are mainly brown spot, and ferruginous spots appear on mushroom stalk and mushroom cover, mainly due to excessive humidity in the shed and poor ventilation.
2. the deformity is mainly manifested in the slender stalk of mushroom, the developed and sturdy root system, and the external shape is like coral in the sea, mainly due to lack of oxygen or poor ventilation in the greenhouse.
3. Overgrowth type: a large number of agglomerated aerial hyphae are produced on the surface of the mycelium of mushrooms, which makes Pleurotus ostreatus grow excessively. The occurrence of this phenomenon is mainly due to excessive humidity in the greenhouse, which affects the normal growth of mushrooms.
In view of the above different types, the following measures should be taken to prevent the occurrence of mushroom diseases. First of all, be careful not to water too much in cultivation, control the humidity in the shed, and let out the air in time when the humidity is too high. In addition, we should also pay attention to the purification and rejuvenation of the strain, the sterilization of the carrier and so on.
In addition, some mushrooms are harmed by mites (red spiders), mainly in the mycelium and fruiting bodies of Pleurotus ostreatus. Individual caps and pleats were also damaged, resulting in many yellow concave spots on the surface of Pleurotus ostreatus, affecting the quality and appearance of Pleurotus ostreatus. In addition, in the production of Pleurotus ostreatus, after seed flies lay eggs at the base of Pleurotus ostreatus, they hatch a large number of larvae (also called maggots), harming various parts of Pleurotus ostreatus.
Control method: whether it is a red spider or a seed fly, 1.8% of the mites can be sprayed 400 to 600 times or 4% of the green vegetable treasure EC 400 to 600 times.

Prevention and control of mushroom virus disease
Once the mushroom virus disease occurs, it will do great harm, not only the decline in production in that year, such as incomplete disinfection of mushroom houses, but also affect next year's harvest. The mushroom hyphae can not form fruiting bodies after infected with the virus, and in severe cases, the mycelia rot, resulting in a large mushroom-free area on the fungus bed. After the mushroom bud was infected with the virus, the fruiting body developed malformed, some had brown spots on the lid and the cap was askew; some had gaps in the cap, the cap and stalk grew unevenly, the cap was very small or the stalk was extra long, or the stalk was bent and sharpened at the lower part of the stalk; or the center of the stalk expanded into a stalk.

Control of mushroom diseases and insect pests
With the further development of mushroom industry, it is very necessary to standardize the control of mushroom diseases and insect pests. This paper puts forward the following suggestions on the prevention and control of mushroom diseases and insect pests: first, the prevention and control of mushroom diseases and insect pests should establish the principles of prevention, comprehensive control and scientific use of chemicals. The specific measures should be as follows: 1. Do a good job in the environmental sanitation of the mushroom house and its surroundings. The environmental hygiene of mushroom house is very important to the occurrence of diseases and insect pests. Must achieve: ① mushroom room and around the clean, sanitary, sterilization should be thorough. Chicken sheds and pig sheds should be kept away from mushroom houses. ② spring mushroom
