Edible mushroom pest and disease control techniques: How to control brown rot?

It mainly harms the fruiting bodies of shaggy ink cap mushrooms (Coprinus comatus), button mushrooms (Agaricus bisporus) and others. If the casing soil is contaminated, spray 50% carbendazim or 70% thiophanate-methyl 500-fold solution on the casing soil to kill the pathogen spores. When disease occurs, immediately stop watering, increase the ventilation of the mushroom house, and lower the room temperature to 15°C; spray the affected area with 50% carbendazim 500-fold solution, or spray 1%-2% formaldehyde solution to sterilize. In severe cases, the original casing soil can be removed and replaced with new soil, the diseased mushrooms burned, and the tools used disinfected with 4% formaldehyde solution.
