How to prevent and cure Agaricus bisporus maculopathy

In the early stage of the disease, there are small spot-like yellowish wards on the gill cap. As the fruiting body grows, it expands the range and infects other fruiting bodies, followed by deepening of the color and expanding the range to the entire cap, and the mushroom body secretes yellow color in the late stage of infection. Brown beads, the diseased plants stopped growing, followed by atrophy and death. Maculopathy is a disease caused by Pseudomonas and is a bacterial pathogen. The pathogen is in a high-temperature and high-humidity environment, especially when the temperature is stable at more than 20°C and the humidity is above 95%, and the concentration of carbon dioxide is high. Induced the disease. Even if the temperature is around 15°C, but the humidity of the mushroom shed becomes saturated (100%) and the airtightness is tight, the disease has a high incidence rate. When the water in the base material and mushroom shed is not clean, the disease incidence is also high. Very high.

Preventive measures: First, do a good job in environmental sanitation, strictly cover soil disinfection, and eliminate pests. The second is to use clean water for spraying water. Avoid spraying water and excess water to prevent the surface of the mushroom body from standing in the state of accumulated water and soil surface to be too wet for a long time. Third, the growth period of fruiting bodies is strictly to prevent excessive humidity in the mushroom house. Strengthen the ventilation to reduce the carbon dioxide concentration in the shed to less than 0.5%, reduce the shed wet, especially in the season when the insulation is needed, the air humidity is controlled at about 85%. Fourth, once the fruiting body is in disease, the ventilation reduces the humidity in the mushroom house and sprays 600 times the bleaching liquid, but it should be noted that after the spraying, it is sealed for 1-2 hours. Then ventilation should be strengthened to reduce the temperature of the greenhouse.
