In the autumn, the pests in the production of edible fungi are still a major threat, even more than in the summer, especially in the autumn season, the temperature difference is widening, so that the pests outside the mushroom shed have been smashed into the shed, even more drama. The difficulty of prevention. Such as mushroom mosquitoes, mushroom flies, spring worms, etc., seemingly insignificant pests, but can cause irreparable damage to production in a short period of time. In particular, pests such as cockroaches, crickets, horses, snails, etc. are larger and more harmful. In actual production, many mushroom farmers do not pay attention to the prevention of pests, and once pests occur, a large number of chemical drugs are used to kill them quickly, and the results are often difficult to achieve. In order to effectively control pests, it is necessary to adhere to the principle of combining prevention and treatment with the principle of “preventing the work under the defense and killing the need to be thoroughâ€. The specific methods come down to three main points:
Physical prevention: 1. The construction of mushroom sheds should leave the village, squat toilets, garbage dumps, manure piles and other places, so that the mushroom environment is far from the insect source. 2. The original auxiliary materials are exposed to strong sunlight to avoid carrying eggs or live insects. 3. There are live insects or eggs in the raw materials. Do not directly sown the raw materials. At least after fermentation, it is best to use clinker for cultivation or for seed production. 4. Strictly check whether the strains are infected with insects. The purchased strains should be carefully checked before transfer to prevent the inoculation of insects. 5. Package insect-proof nets such as mushroom vents and import and export, to prevent adult flying. 6. Spread lime spacers at the vents and inlets to prevent reptile pests from entering.
Drug prevention: 1. Add phoxim and other drugs when mixing. The dosage is generally about 100 ml per 1000 kg of dry material. When the raw material is cultivated, it can be added with the mixture. The best time for fermenting the cultivation is the last time. Adding before turning over the pile, after high temperature and stuffy pile, the insecticidal effect is very good. 2. Within a certain distance outside the shed, after cleaning the waste, high-efficiency insecticides such as trichlorfon can be used to kill the insects and cut off the pests. 3. Ventilation, import and export outside the shed and the shed, using cypermethrin high-efficiency and low-residue drugs to prevent reptiles from entering the shed. 4. Mushroom sheds can generally be sprayed with cypermethrin and other drugs to kill insects, using avermectin to kill mites, for mushroom mosquitoes, mushroom fly pests, conditional use of high-efficiency insect repellent for repelling, the mechanism of action of the drug Yes: It is repelled by the odor of the mushroom mosquito and the mushroom fly that the adult does not like. The adult does not dare to enter the shed, and it is even more difficult to feed the eggs. After the adults are repelled, the larvae that form the damage are inorganic. The odor can make the mushroom mosquito and the mushroom fly hide in fear. Even if they enter the shed, they will quickly escape because of the bad smell and cannot form a harm.
Drug insecticide: When there are live insects or eggs in the strain, the strain can be put into a large plastic bag (wide double-layered shed film, one end of the mouth), according to the amount of 4 pieces per cubic meter of space. Aluminum phosphide can be used for bagging in about 6 hours.
During the period of infection, insects may be accidentally sprinkled, the ground may be sprinkled, the bacteria bags are concentrated (pay attention to temperature, to prevent burning bacteria), the plastic film is covered, and the aluminum phosphide drug is placed under the film. The dosage is the same as above, but attention should be paid evenly. Sealed plastic film, after removing the film for about 6 hours, it can be managed normally.
Pests are found during the emergence of mushrooms. If it is a "slipping net insect" that prevents lax entry, the adult can be sprayed with pyrethroids in an appropriate amount. The adults of mushroom mosquitoes are extremely resistant, according to the lowest concentration of vegetables; if it has been found The larvae can be killed according to the above-mentioned use of aluminum phosphide, but the fruit body should be taken off. For the young buds, the buds can be used, and the initial insects can be completely killed within 4 to 6 hours.
