What are the precautions for pesticide control of edible mushroom diseases and pests

2. It is forbidden to directly use highly toxic agents such as organic mercury and organophosphorus pesticides for mixing into substrate or composting; pesticides with a long residual period, that are difficult to decompose, or that have a pungent odor must also not be used on mushroom beds. In particular, when mushrooms are present on the bed surface, it is absolutely forbidden to use pesticides that are highly toxic, have a long residual period, or have a pungent odor.

3. When controlling diseases and pests, the type of pesticide and the concentration used should be selected according to the target pest. For example, dichlorvos has fumigant and contact-killing effects and is especially effective against adult and larval mushroom flies and springtails, but it has poor killing power against mites; phoxim is a new type of highly effective, low-toxicity, low-residue organophosphorus insecticide, and in addition to being especially effective against mushroom flies and springtails, it also has a good contact-killing effect on mites, with efficacy superior to dichlorvos; if phoxim plus an acaricide is used to control mites, the effect is better than that of other pesticides. The appropriate concentration should be chosen when applying the pesticide: for phoxim plus acaricide, use a 500-fold dilution to prevent mites from the composting stage to before the fruiting stage, but during the fruiting body development stage the concentration should be reduced to a 1000-fold dilution.

4. When using pesticides, first become familiar with the properties of the pesticide.

5. Use botanical insecticides and microecological preparations as much as possible, such as pyrethrum, derris extract, yield-increasing bacteria, and other preparations.

6. Protect natural enemies and do not abuse pesticides.
