In the autumn, insect pests in the production of edible fungi are still a big threat, even worse than in the summer, especially in the autumn season, the temperature difference widens, making pests outside the mushroom shed enter the shed, and even worse. The difficulty of prevention and control. For insects such as mushroom mosquito, mushroom fly, and skipping insects, seemingly insignificant pests can cause irreversible damage to production in a very short period of time. In particular, pests such as cockroaches, cockroaches, horses, and snails are larger in size and more harmful. In actual production, many farmers do not pay attention to the prevention of pests. Once pests occur, a large number of chemical drugs are used in order to kill them quickly. The results are often unsatisfactory. To effectively prevent and control insect pests, we must adhere to the principle of combining prevention and treatment with the principle of “prevention is to work hard and killing is essentialâ€. The specific method boils down to three main points:
Physical prevention: 1. The mushroom shed should be built away from villages, squat toilets, garbage dumps, dung heaps, etc. to make the mushrooming environment away from insect sources. 2. The raw and auxiliary materials are exposed to strong sun exposure to avoid carrying eggs or live insects. 3. There are live worms or eggs in the raw material. Do not directly sow the raw material. Use at least after fermentation. It is better to use clinker for cultivation or for seed production. 4. Strictly check whether the strains have insects, and carefully check the purchased strains before transfer to prevent insect inoculation. 5. Mushroom vents and import and export packages such as insect nets to prevent adult insects from flying in. 6. Spread lime barriers at the vents and entrances and exits to prevent entry of reptile pests.
Drug prevention: 1. Add phoxim and other drugs when mixing, the dosage is generally about 100 ml per 1,000 kg dry material, raw material cultivation can be added with spices, the best time for the cultivation of fermentation materials for the last time Added before turning, high temperature and boring pile, the insecticidal effect is ideal. 2. Within a certain distance from the shed, after cleaning up the waste, insecticides can be killed by using highly effective insecticidal drugs such as trichlorfon to cut off pests. 3. Ventilation outlets and entrances and exits outside the sheds and booths are sprayed with cypermethrin-based high-potency low-residue drugs to prevent reptiles from entering the shed. 4. In mushroom sheds, insecticides such as cypermethrin can be generally sprayed, avermectin can be used to kill aphids, and insecticides such as mushroom and mushroom fly can be used to repell insecticides efficiently, and the mechanism of action of the drug can be repelled. Is: the mushroom mosquito, mushroom fly adults do not like the smell of drugs to repellent, adults do not dare to enter the shed, but also unable to feed spawning, adults are repelled, the formation of harmful larvae will be inorganic. This odor can make mushrooms and mosquitoes hide in a panacea. Even if there are occasional worms, they can escape quickly because of unpleasant odors, and they can't be harmed.
Insecticide: When there are live worms or eggs in the strains, the strains can be packed in large plastic bags (wide double-layered film, and one is tied into the mouth), and the amount of 4 pieces per cubic meter of space is used. Aluminum phosphide can be used after about 6 hours.
During infestation, infestation occurred inadvertently, and the ground was sprinkled with water, and the bacteria bags were concentrated (note the temperature to prevent burning of bacteria). The plastic film was placed after the discharge and the aluminum phosphide drugs were placed under the film. The dosage was the same as above, but care should be taken evenly. Closed plastic film, after about 6 hours to remove the film, you can normal management.
Pests found during fruiting, if it is to prevent sluggish access to the “net of insectsâ€, the amount of insecticide can be suitable for spraying pyrethroids, mushrooms mosquitoes are extremely resistant to insects, according to the minimum concentration of vegetables can be; if found Larvae, according to the above use of aluminum phosphide to kill, but the fruiting body should be removed, for young buds, can be bud medicine, general initial pest, 4 to 6 hours to kill.
