Dry bulb disease is one of the main diseases of Agaricus bisporus. The pathogen has formed infection during the bacterial stage of Agaricus bisporus, and it grows synchronously with the mycelium of the Agaricus bisporus, but it does not show symptoms for the time being. The hyphae invade during the mushrooming stage. The cover of the infected bacteria was dark brown and had a white powder. The stipe was uneven and deformed. The mushroom did not swell, no mucus, and did not become odorous. It eventually became dry and dry. The bacteria live in the soil for a long time and spread widely. Prevention should be started from the treatment of the base material. The selection of high-quality, high-resistance strains is limited to technical conditions. At present, the strains cannot be detoxified. Therefore, high-resistant strains of suitable age should be introduced. Thoroughly clean internal and external sanitization of bacteria culture room and mushroom shed, spray all diseases to traceless liquid spray twice, and use phoxim to treat pests. The spores of the secondary fermentation fungus of the base material germinate in the early stage of fermentation, and are easily killed in the secondary fermentation. Although the cost is slightly higher, the spores can be prevented from occurring. During the growth period, during the period of germination, a mushroom killing agent is sprayed every 3 to 7 days to suppress foreign pathogens. The fruiting period strictly controls the conditions of water, gas, temperature, and light. In particular, it is necessary to strictly maintain the appropriate moisture content in the cover soil and ventilation in the shed, and adhere to the spraying of drugs to prevent foreign pathogens. After the onset of treatment, if the fruiting body is found to be a dry bulb disease hazard, the fruiting body and soil cover material should be expanded in a range of 1 to 2 meters. All the shedding tools should be soaked with a 20-fold dilution of formaldehyde for 3 hours, and then put into 5% lime water for disinfection; The new overlying soil material is treated with all traces of disease without a trace. The carpet scraper in the mushroom shed is sprayed once and for all without a trace; the pest control measures are strengthened; the diseased and buried materials are burned or buried; the stencil and wall are sprayed with multiple bacteria. spirit.
