How to prevent and control insect pests in the production of edible fungi

Edible fungi do not strictly require wet conditions in the mycelial growth stage, but when mushrooms or ears are produced, the relative humidity in the environment needs to be more than 85%, and suitable temperature, ventilation and light are needed. 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. Fermentation or clinker cultivation should be used as far as possible to control the insect population in the culture base, and fermentation materials should be used in the cultivation bed of Pleurotus ostreatus. 0.5% salt, 3% lime, 50% 80% plant ash and so on are added when mixing, which has better deworming and preventive effect.

2. Before entering the shed, the bacteria bag or culture material should be disinfected in the empty shed: spray with 0.3% dichlorvos 0.1% enemy; or fumigate the mushroom house (shed) with 10 g / m3 of aluminum phosphide, fumigate at about 20 ℃ for 48 hours, and fumigate for 24 hours at more than 25 ℃.

3. When the border planting material surface occurs, spraying 1 / 2% washing powder solution has a strong contact killing effect on mushroom flies, adult mites, old and young mites.

4. Making use of the law that some pests like to move in a light-transparent and cool environment, spray liquid such as Mianshiling on the transparent plastic film and cover the border bed once or twice a day for 3 or 4 times in a row, which can kill the adults of flying insects.

5. Install several 15-watt light bulbs or black lights in the pest mushroom house, put a basin of water below, and drop kerosene into the water, which is very effective in trapping and killing adults such as mushroom mosquitoes, fungus mosquitoes and fruit flies.

6. Sugar and vinegar solution trapping: sugar, vinegar, liquor, dichlorvos and water are mixed into a medicine solution according to the proportion of 2, 3, 4, 1, 90, soaked with gauze or cotton balls, wrung out, and placed on the material surface. When the pests smell sweet and sour, they climb onto the cloth or cotton and are poisoned.

7, mix the food that pests like to eat with poison, such as vinegar, sugar, insecticide, fried wheat bran, mix well according to the proportion of 1, 5, 10, 84, sprinkle around the mushroom bed and allow them to feed; for pests such as mushroom flies, mushroom mosquitoes, nematodes, etc., you can also use plant ash pyrethrum (1 g / m2) to evenly sprinkle a layer on the material surface for 2 to 3 days, the effect is very good, both insect control and disease prevention.
