Detailed Explanation of Chemical Control Methods for Oyster Mushroom Pests and Diseases

Chinese 1. Lime: When fermenting the raw materials, add 4%-5% quicklime powder for high-alkali treatment to improve disease resistance; treat the mushroom house walls and mushroom racks with concentrated limewater; after harvesting mushrooms, spray with the supernatant of limewater, which helps prevent disease and increase yield; when there is localized damage from wood (green) mold, sprinkle lime powder on the contaminated areas to control its spread, etc.

2. Sulfur: Before bringing materials into the mushroom house, fumigate and disinfect with sulfur at multiple points, at a dose of 5 grams per cubic meter.

3. Formaldehyde: When mushroom bags are locally infected with Trichoderma and other contaminating fungi, apply a 2% formaldehyde solution.

4. Bleaching powder: If mushroom bags are locally contaminated by miscellaneous fungi, apply a 10% bleaching powder aqueous solution; before use, disinfect mushroom house (shed) walls, floors, bed racks, etc. with a 150-fold bleaching powder aqueous solution.

5. Trichlorfon: Before fruiting and after harvesting mushrooms, spray with a 1000-fold solution of 90% trichlorfon to prevent an outbreak of mushroom flies.

6. Dichlorvos: Regularly spray around the mushroom house with a 1000-fold solution of 50% dichlorvos to eliminate insect sources.

7. Deltamethrin: When mushroom flies occur severely, after harvesting mushrooms, spray with a 1500-2000-fold solution of 2.5% deltamethrin.

8. Poison bait trapping: For pests whose adults like to feed or lay eggs on rotten fruit or fermented matter, take some rotten fruit or distillers' grains and place them on a plate, then pour in a small amount of 1000-fold solution of 50% dichlorvos to trap and kill them.
