Pleurotus ostreatus virus disease is an important disease of Pleurotus ostreatus, which occurs widely throughout the country and can cause significant reduction in production. It is a disease caused by viruses whose pathogens are spherical virus particles. Pleurotus ostreatus has no obvious symptoms after infection with the virus. Because the virus is parasitized in the cells, only the growth rate of the mycelium is slowed down, and the edges of the colonies are not always neat. By the time of the mushrooming period, after the infection of the virus, some fruit stalks of the fruit bodies are nearly spherical or flask-shaped and do not form bacteria. The cover may only have a small cap, or only keep the traces of the cap on the top surface of the near-spherical fruiting body, and later it will produce cracks, exposing white bacteria; some stipe flattened or curved, uneven surface Or with knob-like projections, the cap is deformed to a small degree, with deep nicks and wavy patterns; some of the caps and stipe on the stipe appear obvious water-stained stripes or streaks. Severely diseased fruit bodies cannot form spores. Some have been hindered by development, dwarfing mushrooms, thick cover, short shank or small cover. In brief, the symptoms of Pleurotus vires disease are as follows: 1 Stigma swollen nearly spherical or flask type, sterile cap or very small cap; 2 The bacilli are flatly curved, the surface is convex or concave, or the knobs are convex, and the caps are deeply missing and wavy; 3 There are obvious water-stained stripes or streaks on the cap and stipe. The spherical virus of Pleurotus ostreatus is transmitted through the fusion of the basidiospores and mycelia. The virus-carrying strains or the bran-dried spores with the virus fall on the mushroom bed. The spores germinate and form mycelia with virus particles. Can be spread through the interweaved fusion between healthy mycelium and infected mycelium. It is the main condition of the disease. There is a lot of evidence that hyphae is the main route of transmission of the virus. Control methods: 1 Breeding disease-resistant and disease-resistant strains and breeding virus-free strains; 2 Strictly put a good mother off. Abnormal growth, especially the mother of the mycelium is not neat to be removed; the original species, growth species in the cultivation phase should always check, where there is a lack of hyphae or flower plaque must be firmly eliminated; 3 The mushroom shed, the culturing room, and the inoculation tools must be strictly sterilized with drugs such as "sterile disinfection king" and "venus disinfectant". 4 Pleurotus ostreatus bags that have been found to be infected with viruses have been isolated and burned. After the end of production, the diseased mushroom house is strictly sterilized. The mushroom bed frame is disassembled and cleaned to prevent the spores and hyphae that carry virus particles from being lurking in the frame joints. 5 When the bacterial bag or fruiting body has symptoms of viral disease, it is sprayed with "Strong Virus Clear" 600 times liquid and sprayed once every 4 days. The cure rate is 94%. 6 After the cultivation is completed, strict disinfection and fumigation treatment should be used for the bed frame and mushroom house with serious virus disease to prevent the infected spores and mycelia from long-term lurking.
