How to reduce pests in edible mushrooms? A detailed guide to practical control methods

1. Keep the mushroom yard clean. Before cultivation, the mushroom house must be thoroughly cleaned, and evenly sprayed with an 800-fold dilution of trichlorfon or dichlorvos solution. For outdoor mushroom growing, clear the weeds around the cultivation site, and spray the soil and the surrounding area with a 250-fold dilution of trichlorfon solution.

2. Prevent adult insects from entering the room. For indoor mushroom cultivation, nail 60-mesh fine gauze over doors, windows, ventilation holes and the like to prevent adult flies, mushroom mosquitoes and other adult insects from entering the room and causing damage.

3. Fumigation with chemicals. For indoor edible mushroom cultivation, under sealed conditions, fumigate with 2-3 tablets of aluminium phosphide per cubic meter of space to eliminate indoor insect sources.

4. Treat the growing substrate. For every 50 kg of substrate, use 15 ml of dicofol, mix with 10 kg of water, and spray evenly onto the substrate, stirring the substrate while spraying; after spraying, pile it up for 3 days to eliminate insect sources in the substrate. Alternatively, mix a 500-fold dilution of 40% phoxim into the substrate; both give very good insecticidal results.

5. Spray chemicals to kill insects. If pests are found before mushrooming, spray the bed surface with a 500-fold dilution of trichlorfon solution, or a 1000-fold dilution of kill solution, or an 800-fold dilution of dichlorvos solution to kill the insects.
