Chemical Control of Diseases and insect pests of Pleurotus ostreatus
1. Lime: when the raw material is fermented, 4%-5% quicklime powder is added for high alkali treatment to improve its disease resistance; the walls and shelves of mushroom houses are treated with concentrated lime water; after mushroom picking, spraying with lime water supernatant is conducive to disease prevention and high yield; when local Trichoderma is harmful, sprinkle lime powder on the polluted place to control the spread, and so on.
two。 Sulfur: multi-point fumigation and disinfection with sulfur before feeding in the mushroom room, the dose is 5g / m3.
3. Formaldehyde: when the bacterial bag is locally infected by Trichoderma and other miscellaneous bacteria, smear with 2% formaldehyde solution.
4. Bleaching powder: bacteria bags locally contaminated with miscellaneous bacteria, can be smeared with 10% bleach solution; mushroom (shed) wall, floor, bed frame, etc., disinfected with 150 times bleach solution before use.
5. Trichlorfon: spray 1000 times of trichlorfon before and after mushroom picking to prevent the spread of mushroom mosquitoes.
6. Dichlorvos: regularly spray 1000 times of dichlorvos around the mushroom room to eliminate the source of insects.
7. Deltamethrin: when the occurrence of mushroom mosquitoes is serious, spray 2.5% deltamethrin 1500-2000 times after mushroom picking.
8. Poison bait: adults like to eat or lay eggs on rotten fruit or fermentation, can take some rotten fruit or wine residue on the plate, pour a small amount of 50% dichlorvos 1000 times solution to kill.

Techniques for reducing pests of Edible Fungi
Keep the mushroom farm clean. The mushroom house should be thoroughly cleaned before cultivation and sprayed evenly with 800 times of trichlorfon or dichlorvos solution. To grow mushrooms outdoors, remove weeds around the cultivation site and spray the soil and around the site with 250 times trichlorfon solution. 2. Prevent adults from entering the house. For indoor cultivation, doors and windows, ventilation vents and so on should be nailed with 60-mesh fine yarn to prevent adults such as flies and mushroom mosquitoes from entering the room. 3. Drug fumigation. Indoor cultivation of edible fungi, and then under airtight conditions, per cubic meter

Control of Diseases and insect pests of Pleurotus ostreatus
In the cultivation of Pleurotus ostreatus; diseases and insect pests stand in the way. Understanding and timely prevention and control are of great significance to normal production. Diseases and insect pests are found; if no timely measures are taken, the yield of Pleurotus ostreatus will be seriously affected, sometimes resulting in no harvest. Therefore, we should select excellent and highly resistant bacteria, strengthen scientific management, and create environmental conditions conducive to mushroom growth but not conducive to the reproduction of diseases and insect pests. Some common control methods of diseases and insect pests are introduced as follows: 1. Diseases are common in the following two categories: (1) in the process of cultivation, environmental conditions and management
