Precautions for pesticide control of edible fungi pests and diseases

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 the control of diseases and insect pests, the type 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.

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.
