Pleurotus ostreatus disease, also known as yellow rot. It is a bacterial disease caused by discoloration and rot of Pleurotus ostreatus caused by monocytogenes. It has four polar hairs, 0.5-0.7 μm, 1.0-3.0 μm, and belongs to aerobic gram-negative bacteria. Occur from the edge of the cap, can also start from the stipe, the infected mushroom body grows slowly, aging faster, and the color is dark, quickly softened, yellow, brown, bitter, and then rot. And it emits a foul odor,
Studies have found that this type of monospora is mainly parasitized in soil and water. Spraying water with this virus on fruiting bodies will not cause disease at low temperature and low humidity. Only after a large number of reproduction on the surface of the cap can cause disease, poor ventilation, high humidity and prolonged maintenance of water on the surface of the cap, are easy to cause disease, once the mushroom body onset. 4-7 days can reach the entire shed or surrounding mushroom shed. And since then there has been no listing of a good mushroom, and even no harvest. Under normal circumstances, only 5-8 days from the discovery of the symptoms to the lice and the whole mushroom shed, it can be said that explosive power, the disease deteriorated quickly.
Treatment of Mushroom Disease: When there is 0.5% mushroom bag in the shed where M. edodes disease occurs, this time it belongs to the initial stage of disease. The water spray should be stopped immediately, the mushroom should be removed, and the temperature in the winter shed in the northern region should be taken immediately. Reduced to below 15°C, and treated with the following methods: 1. Spray Wanmaring and agricultural streptomycin mixture on bag and surrounding gold within 12 hours (100 kilograms of water plus 15 pieces of Wan Xiao Ling and 1 bag of agricultural chain Once a day, spray three days. 2, spray Baoqing liquid, each bag 10g Duishui 50kg, 2 days apart to the head of the mushroom spray. 3 Use yellow rot and other special drugs to spray. The above method requires 15-30 minutes of large ventilation after each spraying, and normal ventilation is still used. About three days later, M. edodes disease disappeared and the disease stopped spreading. After the mushroom disease disappeared, the shed was still managed by low humidity. In addition to spraying on a windy day, water spray was generally not required to prevent the recurrence of yellow mushroom disease.
