Mushroom virus disease is harmful

Once the mushroom virus disease occurs, it is very harmful. Not only did the output of the mushroom production decline, but the disinfection of the mushroom house was not complete, and it would affect the harvest of the following year. Mushroom hyphae are not able to form fruit bodies after being infected with virus. In severe cases, the mycelium rots, resulting in a large mushroom-free area on the bed of bacteria. Mushroom bud infection, the development of fruiting bodies was deformed, some brown spots appeared on the caps, cap tilt; some caps have gaps, cap and stipe growth is not balanced, special small or stipe special characteristics; Or the stipe is bent, the lower part of the stipe is sharpened; or the stipe is swollen in the center to become a stalk or altar; some of the mushroom body is water-stained and the squeeze stipe is water. The prevention measures are as follows: 1. Always change the variety when growing. Each species in the same area, continuous use of no more than 2 years, a variety of strains to be used interchangeably (referring to the type of adherence and air type), to avoid continuous strains to adapt to the decline in the ability to become infected with the virus. 2. Before and after each cultivation, all the mushroom sheds (shelves) and tools must be sterilized with 5% formaldehyde, and it can also be sterilized with bromide and methyl bromide, especially the bed frames and floors of old mushroom sheds (rooms), and should be strictly sterilized. . 3. Before cultivation, in addition to sterilizing mushroom sheds (rooms), 10 to 20 pieces of Wan Xiao Ling (sold in hospital) are shallowly buried in the four corners. After the materials are cultivated at the same time, the material surface is covered with newspapers, 0.5% per week. Formaldehyde sprays wet newspaper twice until it covers the soil. 4. Mushroom sheds and mushrooms that have been found to have viral disease must be harvested before the opening of the umbrella and are then sprayed with 2% formaldehyde to prevent spores from spreading.
