Cultivation techniques of Pleurotus ostreatus: how to prevent and cure Pleurotus ostreatus virus disease?

How to prevent and cure Pleurotus ostreatus virus disease? What harm does Pleurotus ostreatus virus disease have? Also ask experienced netizens to help introduce the harm and prevention of Pleurotus ostreatus virus disease, the following is a detailed introduction (for your reference). The harm of Pleurotus ostreatus virus disease: Pleurotus ostreatus virus disease is a disease caused by virus, its pathogen is spherical virus particles. The mycelium of Pleurotus ostreatus had no obvious symptoms after infection with the virus. Because the virus is parasitic in the cell, but the growth rate of the hyphae slows down, and the edge of the colony is often irregular; at the mushroom stage, after being infected with the virus, some fruiting body stalks swell in the shape of a nearly spherical or flask, which will not form a cap or will only appear a very small cap, or only leave traces of the cap on the top of the near-spherical fruiting body, and cracks will occur in the later stage, exposing white flesh. Some stalks become flat or curved, the surface is uneven or have tumor-like protuberances, the cap becomes small and deformed, with deep engraving and wavy type, and some obvious water-stained stripes or stripes appear on the cap and stalk. The fruiting bodies with severe disease could not form basidiospores. Some due to hindered development, mushroom type dwarfing, thick cover, short handle or small cover. Pleurotus ostreatus virus disease control methods: 1. Select disease-resistant and disease-tolerant strains and virus-free strains. 2. 2. Strictly control the mother breed. The mother species with abnormal growth, especially irregular hyphae should be eliminated; the original species and growing species should be checked frequently during the culture stage, and those with missing hyphae or flower patches should be resolutely eliminated. 3. The mushroom shed, culture room and inoculation tools should be strictly disinfected with drugs such as "bacterial room disinfection king" and "Jinxing disinfectant". 4. The bags of Pleurotus ostreatus found to be infected with virus diseases should be singled out, isolated and burned. After the end of production, the disinfected mushroom house was strictly disinfected, and the mushroom bed rack was taken apart and cleaned to prevent spores and hyphae carrying virus particles from lurking in the cracks. 5. When there are symptoms of virus disease in the bacterial bag or fruiting body, spray with 600 times liquid of "strong virus clear", spray once at intervals of about 4 days, and the cure rate is 94%. 6. After the end of cultivation, the bed frame and mushroom room with serious virus disease should be strictly fumigated and disinfected by "bacterial room disinfection king" to prevent the infected spores and mycelium from latent for a long time.
