The widening of temperature difference in winter caused pests outside the mushroom sheds to enter the shed, which exacerbated the difficulty in controlling insect pests. In actual production, many farmers do not pay attention to prevention. Once pests occur, even if a large number of chemical drugs are used to quickly kill pests, the results are often unsatisfactory.
Physical precautions Since there are live worms or eggs in the raw material, do not directly sow the raw material, use it at least after fermentation, and it is best to use clinker for cultivation or for seed production. Strictly inspect whether the strains carry insects, and carefully check the purchased strains before transfer to prevent insect inoculation. Mushroom shed ventilation and import and export, and other places, to seal insect nets to prevent adults fly into. Liby barriers are scattered at the air 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 of dry material, raw material cultivation can be added with spices, the best time for the cultivation of fermentation material for the last time Added before the heap, the high temperature and stuffy heap, the insecticidal effect is ideal. 2. Within a certain distance from the shed, after cleaning up the waste, insecticides such as trichlorfon can be used 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 mosquitoes and mushroom fly insects can be efficiently repelled using insecticides.
