The principle of using pesticides to control diseases and insect pests of edible fungi and to explore the high-yield cultivation techniques of edible fungi.

1. During the period of mushroom production, pesticides should be used very cautiously. Pesticide contamination on mushrooms will cause food pollution. At present, countries all over the world are very strict with the testing of pesticide residues in food, and pesticide residues will affect the quality of products and market competitiveness.

2. It is forbidden to directly use highly toxic organic mercury, organophosphorus and other chemicals in mixing and stacking materials; pesticides with long residual period, not easy to decompose and irritating odor can not be used in mushroom beds. Especially when there are mushrooms on the bed, it is absolutely forbidden to use agents with strong toxicity, long residual period or irritating odor.

3. In order to control diseases and insect pests of edible fungi, the pesticides with high efficiency, low toxicity and low residue should be selected, and the types and concentration of pesticides should be selected according to the control object. If dichlorvos has fumigation and contact effect, it has special effect on adults, larvae and jumpers of mushroom flies, but has poor killing effect on mites; phoxim is a new type of organophosphorus insecticide with high efficiency, low toxicity and low residue, which not only has special effect on mushroom flies and jumping insects, but also has good contact effect on mites, and its efficacy is better than that of dichlorvos; if phoxim plus acaricides is used to control mites, the effect is better than other pesticides. The appropriate concentration of phoxim and acaricide should be selected, and 500x solution should be used to control mites from composting to pre-mushroom stage, but the concentration should be reduced to 1000 times in the development stage of seed body.

4. When using pesticides, you should first be familiar with the nature of pesticides. Abuse of pesticides sometimes forms a layer of toxic substances on the surface of the overlying soil or culture materials, affecting the growth of mycelium and reducing production.

5. Use botanical pesticides and microecological agents as much as possible, such as pyrethrum, fish rattan essence, yield-increasing bacteria and so on.

6. Protect natural enemies and do not abuse pesticides.
