1. During the mushrooming period, pesticides should be used with great care. Contamination of pesticides on mushrooms can cause food contamination. Now all countries in the world are very strict on the inspection of residual pesticides in foods. Pesticide residues will affect the quality of products and market competitiveness. 2. It is forbidden to directly use highly toxic organic mercury, organic phosphorus, and other chemicals to mix and pile materials; pesticides that have a long residual effect, are not easily decomposed and have irritating odors, and cannot be used for mushroom beds. Especially when there are mushrooms on the bed, it is absolutely forbidden to use drugs with strong toxicity, long residual period, or pungent odor. 3. In the prevention and control of pests and diseases of edible fungi, high-efficiency, low-toxicity, low-residue medicaments should be selected, and the types and concentrations of the medicaments should be selected according to the control subjects. For example, dichlorvos have the effects of smoke killing and contact killing, and they have special effects on adults, larvae and collembodins of Mushrooms, but they have poor lethality against fleas. Phoxim is a new type of highly effective, low-toxicity, low-residue organophosphate insecticide. The agent, in addition to the special effects on the mushroom fly and the hopper, also has a good contact effect on the fleas and its efficacy is better than that of dichlorvos. If phoxim plus miticides are used to control fleas, the effect is better than other pesticides. Applicator should choose the appropriate concentration, phoxim plus acaricide, from the compost to the mushrooming period, each with 500 times liquid to prevent flooding, but the seed body development stage concentration should be reduced to 1000 times liquid. 4. When using pesticides, be familiar with the nature of pesticides. The abuse of pesticides can sometimes form a layer of toxic substances on the surface of the cover soil or culture materials, affecting the growth of mycelia and causing a reduction in production. 5. Use plant insecticides and probiotics as much as possible, such as pyrethrum, rattan extract, and production-promoting bacteria. 6. Protect natural enemies and do not abuse pesticides.
