Main diseases and insect pests of Pleurotus ostreatus and their control
The most serious damage is miscellaneous bacteria pollution, the common miscellaneous bacteria are Trichoderma, green mold, yellow mold, Rhizopus and so on. The main prevention and control methods are as follows: the materials without mildew are selected, the culture materials should be stacked and fermented and sterilized, the cultivation sites should be strictly disinfected, and those found to be contaminated should be cleaned out in time. Proper ventilation to prevent excessive temperature and humidity.
Physiological diseases often occur in the cultivation of ① mushrooms: part of Pleurotus ostreatus dies: when there are too many mushrooms, some will die, mainly due to undernutrition and "starvation"; premature spraying of water or too high humidity will also cause the death of small mushrooms. ② Pleurotus ostreatus: it is often caused by poor ventilation and high carbon dioxide concentration. ③ young mushroom withered: mainly because the culture material was too dry or the air humidity was too low.
The main pests in the cultivation of Pleurotus ostreatus are mushroom flies and so on. Generally speaking, the method of controlling miscellaneous bacteria can better control pests such as mushroom flies. At the same time, try to prevent the plastic bag from being damaged in the process of moving.

Control techniques of common insect pests in Pleurotus ostreatus
The common pests of Pleurotus ostreatus are mushroom flies, mushroom mosquitoes, mites, nematodes, jumpers and slugs. In their egg-laying culture medium, the larvae reproduce in the culture medium, which harms the mycelium and causes the culture material to rot. Adults such as night moths also eat the stalk and mycelium of Pleurotus ostreatus and spread pathogens. In addition, the whole process of cultivation and mushroom production should be prevented. Rats eating mushroom seeds, crawling bed materials or biting mushroom bags are also problems that lead to reduced production. Preventive measures: pay attention to environmental hygiene, clean inside and outside the mushroom before planting mushrooms, spray with formalin, dichlorvos or pyrethroids, or smoke with aerosol

Eight methods of skillfully treating insect pests of Edible Fungi
The prevention and control of insect pests (mushroom mosquitoes, mushroom galls, jumping insects, mites, nematodes, etc.) in the production of edible fungi is a headache for mushroom farmers. Now I would like to introduce to the mushroom farmers several skillful methods for the treatment of edible mushroom pests for reference. 1. Try to use fermentation or clinker cultivation to control the insect population in the culture base, and the cultivation bed of Pleurotus ostreatus should use fermentation material. 0.5% salt, 3% lime, 5% lime and 8% plant ash are added when mixing, which has better deworming and preventive effect. 2. Before entering the shed, the bacterial bag or culture material should be disinfected in the empty shed: use 0
