"Green" Control of Mushroom pests

Nowadays, green food has become the mainstream of food, but in actual production, especially in autumn, mushroom farmers use a large number of chemical drugs to control insect pests, which makes a large number of residual drugs in mushroom products, which not only lays a hidden danger to the health of consumers, but also blocks the path for mushroom products to enter the market, especially the international market.

So, how to carry out "green" pest control? There are two measures:

The first is to strengthen physical prevention. Measures include: the construction of mushroom sheds should be far away from stable toilets, garbage, dung piles and other places, so that the environment is insect-free or insect-free; raw and auxiliary materials are exposed to strong sunlight to avoid carrying eggs or live insects; packaging insect-proof nets at vents and entrances and exits of mushroom sheds, and spreading lime barriers at vents and entrances and exits to prevent reptiles from entering.

The second is to choose drugs reasonably. Within a certain distance outside the shed, highly effective insecticidal drugs such as trichlorfon and dichlorvos can be used to kill insects in order to cut off the route of pests. Outside the shed, ventilation, import and export, use high-efficiency and low-residue drugs to spray to prevent reptiles from entering. The green biological drug, high-efficiency paracetamol, was used in the shed. The action mechanism of the drug is to use the drug smell that the adults of mushrooms, mosquitoes and flies do not like to repel them, so that the adults do not dare to lay eggs near the material and do not dare to enter the shed, so they can not form harm. Usage: generally in autumn, 2 Mel should be sprayed once every 3 days, with a concentration of 200 times. In areas with poor environment and high population density, the concentration can be increased to about 100 times, or the interval between drugs can be reduced to 1 Mel for 2 days.
