How to use drugs to prevent insect pests of edible fungi.

Anti-pest techniques of drugs for edible fungi.

1. Phoxim or poison and other drugs are added when mixing, the dosage is generally about 100ml per 1000 kg of dry material, and can be added with the mixture during raw material cultivation, and the best time for fermentation material cultivation is to be added before the last turn of the pile, after high temperature and stuffy heap. the insecticidal effect is ideal.

two。 Within a certain distance outside the shed, after cleaning up the waste, highly effective insecticidal drugs such as trichlorfon can be used to kill insects and cut off the source of pests.

3. Outside the shed and the vents, entrances and exits of the shed, cypermethrin drugs with high efficiency and low residue were sprayed to prevent reptiles from entering the shed.

4. In the mushroom shed, drugs such as cypermethrin can be sprayed to kill insects, avermectin is used to kill mites, and high-efficiency paracetamol can be used to ward off mushroom mosquitoes and mushroom fly pests under certain conditions. the action mechanism of the drug is: the use of mushroom mosquitoes, mushroom fly adults do not like the drug smell to ward off, adults do not dare to enter the shed, let alone feed to lay eggs, adults are repelled, the formation of harmful larvae will have no opportunity to take advantage of. The smell can make mushroom mosquitoes, mushroom flies to avoid, even if occasionally into the shed insects, but also because of the unpleasant smell and quickly escape, unable to form harm. Usage: generally in autumn, spray once every 2 days, and 200 times liquid concentration is suitable. For areas with poor environment and high insect population density, the concentration can be increased to about 100 times liquid, or the interval between drugs can be reduced to 1 day. The drug is a biological preparation, non-toxic, no residue.

1. Try to adopt fermentation or clinker cultivation to control the insect population in the culture base, and the cultivation bed of Pleurotus ostreatus should adopt fermentation material. 0.5% salt, 3% lime, 5-8% 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 for 48 hours at about 20 ℃ and 24 hours at more than 25 ℃, the insecticidal effect can reach 95-100%.

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. 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, mosquitoes and fruit flies.

5. 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.

6. Making use of the law that some pests like to move in the light-transparent and cool environment, spray the liquid such as Mianshiling on the transparent plastic film and cover the border bed 1-2 times a day, 3-4 times in a row, which can kill the adults of flying insects.

7. Mix the food that pests like to eat with poison. For example, mix vinegar, sugar, insecticide and fried wheat bran according to the proportion of 1R5 / 10R84 and sprinkle around the mushroom bed and the material surface to allow them to feed; 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 for 2-3 days, the effect is very good, not only can control insects but also prevent diseases.

8. In the low temperature season, the method of "first pointing and then killing" can be adopted for mites and other pests in the border bed: on a sunny morning, spray the 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. If it lasts for 3-5 times, the pests can be eliminated. Create environmental conditions to inhibit the occurrence of diseases, insects and miscellaneous bacteria. Make use of the gap between the occurrence conditions of miscellaneous bacteria, diseases and insect pests and the range of growth and development conditions of edible fungi, adjust temperature, humidity, moisture, light, pH, nutrition and air conditions, restrain the harm of miscellaneous bacteria and diseases and insect pests, and promote the normal development of edible fungi.
