How to prevent and cure yellow spot of Pleurotus ostreatus?

How to prevent and cure yellow spot of Pleurotus ostreatus? Please introduce the method: there is a small spot light yellow disease area on the cover of Pleurotus ostreatus yellow spot at the initial stage of infection, and with the growth of the fruiting body, the scope expands and infects other fruiting bodies, then the color becomes darker and extends to the whole bacterial cap. In the later stage of infection, the mushroom body secretes yellowish brown water droplets, and the diseased plant stops growing, then shrinks and dies. Yellow spot is a disease caused by Pseudomonas aeruginosa, which is a bacterial pathogen, which likes high temperature and humidity, especially when the temperature is more than 20 ℃, the humidity is more than 95%, and the concentration of carbon dioxide is high, it is very easy to induce the disease. Even if the temperature is about 15 ℃, but the humidity of the mushroom shed tends to be saturated and airtight, the incidence of the disease is also high, and the incidence of the disease is also very high when the base material and the water in the mushroom shed are not clean. Prevention and control measures: first, do a good job in environmental hygiene, strictly cover soil disinfection, and eliminate pests. Second, spray water must use clean water, do not spray door water, excessive water, to prevent the mushroom surface in a long-term state of stagnant water and soil surface is too wet. Third, the humidity in the mushroom room should be strictly prevented during the fruiting body growth period. Strengthen ventilation, reduce the concentration of carbon dioxide in the shed to less than 0.5%, and reduce the humidity of the shed, especially in the seasonal period when heat preservation is needed, the air humidity is controlled at about 85%. Fourth, once the fruiting body occurs, ventilation will reduce the humidity in the mushroom room and spray 600 times bleaching powder, but it should be noted that the shed should be sealed for 1-2 hours after spraying. Then the ventilation should be strengthened and the temperature of the shed should be reduced. Click to get more planting techniques of Pleurotus ostreatus
