What are the green control methods for mushroom pests?

Today green food has become the mainstream of food, but in actual production, especially in autumn, mushroom farmers use large amounts of chemical drugs to control pests, which leaves large amounts of drug residues in mushroom products, planting hidden dangers for consumers' health and also blocking the path of mushroom products into the market, especially the international market.

So how should pests be controlled in a "green" way? There are two measures:

First, strengthen physical prevention. Measures include: mushroom sheds should be built far from stables and latrines, garbage, manure piles and other places, so that the environment has few or no insects; raw and auxiliary materials should be exposed to strong sunlight to avoid carrying insect eggs or live insects; ventilation openings and entrances and exits of mushroom sheds should be sealed with insect-proof nets, and lime isolation belts should be spread at ventilation openings and entrances and exits to prevent crawling insects from entering.

Second, choose drugs reasonably. Within a certain distance outside the shed, high-efficiency insecticides such as trichlorfon and dichlorvos-type drugs can be used to kill insects, so as to cut off the route by which pests arrive. Outside the shed and at ventilation openings and entrances and exits, high-efficiency low-residue drugs should be sprayed to prevent crawling insects from entering. Inside the shed, a green biological drug - high-efficiency insect repellent - should be used for repellence. The mechanism of action of this drug is: it uses the drug odor that adult mushroom mosquitoes and mushroom flies dislike to repel them, so that the adults do not dare to approach the substrate to lay eggs and do not dare to enter the shed, and therefore cannot cause harm. Method of use: generally in autumn, spray once every 2-3 days, preferably at a 200-fold concentration; in areas with a poor environment and high insect population density, the concentration can be increased to about 100-fold, or the interval between applications can be shortened to 1-2 days.
