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: kill and smoke with 0.3% dichlorvos + 0.1% enemy. Or aluminum phosphide 10 grams / cubic meter fumigation, closed mushroom room (shed), about 20 ℃ fumigation 48 hours, more than 25 ℃ fumigation 24 hours, insecticidal effect can reach 95% 100% (note: aluminum phosphide is highly toxic, pay attention to safety when using), mainly for mushroom nematodes, mushroom flies, mushroom mosquitoes and mites.

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 shady environment, the liquid such as Mianshiling is sprayed on the transparent plastic film and covered on 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 room, 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, mosquitoes and fruit flies.

6. Sugar and vinegar solution trapping: sugar, vinegar, liquor, dichlorvos and water were mixed into 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.

7. Mix the food that pests like to eat with poison, such as vinegar, sugar, insecticide, fried wheat bran according to the proportion of 1 ∶ 5 ∶ 10 ∶ 84, sprinkle around the mushroom bed and let them eat; for mushroom flies, mushroom mosquitoes, nematodes and other pests can also be evenly sprinkled with plant ash + pyrethrum (1 g / m2) on the material surface, even 2-3 days, the effect is very good, both insect control and disease prevention.

8. In the low temperature season, the method of "luring and then killing" can be adopted for mites and other pests in the border bed: on a sunny morning, spray sweet and sour liquid on the bed, cover the film, open the grass curtain, and heat up. At this time, a large number of pests will climb to the bed or film from the depths; in the afternoon, remove the film in time, take it out of the mushroom shed, wash the attached insects with water, and spray the bed with high-dose and low-toxic insecticides. In this way, the harm can be eliminated for 3 or 5 times in a row.
