Beware of insect pests when planting edible fungi in autumn

In autumn, pests in edible mushroom production are still a major threat, even more than in summer, especially in late autumn, the temperature difference widens, which makes the pests outside the mushroom shed one after another, which aggravates the difficulty of prevention and control. Such as mushroom mosquitoes, mushroom flies, jumping insects and so on, seemingly insignificant pests can cause irreparable losses to production in a very short time. In particular, the pests such as mole cricket, cricket, horse land, snail and so on are larger and more harmful. In actual production, many mushroom farmers do not pay attention to the prevention of pests, but once pests occur, they use a large number of chemical drugs to kill them quickly, and the results are often difficult to be satisfactory. In order to effectively control insect pests, we must adhere to the principle of combination of prevention and control. The specific methods can be summed up as follows:

Physical prevention: 1. The mushroom shed should be built away from villages, stable toilets, garbage dumps, dung piles and other places, so that the mushroom environment is far away from the source of insects. two。 Raw and auxiliary materials are exposed to strong sunlight to avoid carrying eggs or live insects. 3. If there are live worms or eggs in the raw materials, do not sow seeds with raw materials directly, at least use them after fermentation treatment, and it is best to adopt clinker cultivation or seed production. 4. Strictly check whether the bacteria are infected with worms, and carefully check the purchased strains before transfer to prevent the phenomenon of worm-carrying inoculation. 5. The vents of the mushroom shed and the entrance and exit of the mushroom shed are encapsulated with anti-insect nets to prevent adults from flying in. 6. Spread lime barriers at vents and entrances and exits to prevent reptiles from entering.

Drug prevention: 1. When mixing, phoxim and other drugs are added, the dosage is generally about 100ml per 1000 kg of dry material, and can be added with the mixture during the cultivation of raw materials. the best time for the cultivation of fermented materials is to be added before turning the pile for the last time, 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 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. 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.

Drug insecticidal: when there are live insects or eggs in the bacteria, the bacteria can be loaded into a large plastic bag (wide double-layer greenhouse film, which can be made at one end), put into aluminum phosphide according to the dosage of 4 tablets per cubic meter of space, and the bag can be used in about 6 hours.

During the germicidal period, if insect pests occur inadvertently, you can sprinkle water on the ground, cover the plastic film after the bacterial bag is concentrated (pay attention to the temperature to prevent burning bacteria), and put aluminum phosphide drugs under the film, the dosage is the same as above, but pay attention to the uniform and airtight plastic film, after removing the film for about 6 hours, it can be managed normally.

If pests are found during mushroom emergence, if they are not strictly prevented from entering the net, pyrethroids can be sprayed appropriately on adults, and adults of mushrooms and mosquitoes are extremely drug-intolerant, according to the lowest concentration of vegetables; if larvae have been found, aluminum phosphide can be used to kill according to the above mentioned, but the fruiting body should be harvested. For young buds, drugs can be used with buds, generally the first pests can be killed in 4 hours.
