First, implement physical prevention. Its main measures include:
(1), the construction of mushroom sheds should be away from squatting, garbage, manure piles and other places, so that the environment is less insects or insects.
(2) The raw and auxiliary materials are exposed to strong sunlight to avoid carrying eggs or live insects.
(3), package insect-proof nets such as mushroom vents and import and export, and sprinkle lime isolation belts at the vents and inlets to prevent reptiles from entering.
Second, a reasonable choice of drugs. High-efficiency insecticides such as trichlorfon and dichlorvos can be used to kill insects at a certain distance outside the shed to cut off pests. Outside the shed and vents, import and export, use high-efficiency and low-residue drugs to prevent reptiles from entering. The use of green biopharmaceuticals in the shed - efficient insect repellent for repelling. The mechanism of action of the drug is to use the drug odor that the mushroom mosquito family does not like to evade, so that the adult does not dare to lay eggs, and does not dare to enter the shed. Therefore, no harm can be formed.
Usage: Generally spray once every 2~3 days, 200 times concentration is appropriate, the environment is poor, the density of insect population is large, the concentration can be increased to about 100 times, or the interval between medications can be reduced to 1~2 days.
