I. Symptoms When the mushroom fruit body is infected with Fusarium, the differentiation of fruit bodies is hindered and malformation mushrooms are formed. If the mushroom stalks and stalks become diseased after differentiation, the stalks turn brown. Infected at the end of fruit body development, fruiting bodies appear horny brown spots and no pathogenic hyphae are visible. If mushroom tissue stays on the mushroom bed, it will gradually turn brown and exude brown liquid. Second, the prevention and control methods (a) cover soil suitable for use 15 cm below the surface of the soil, so as to avoid the surface pests and diseases brought into the mushroom house. After the cover soil was taken back, it was exposed to the dry state under the hot sun, and the soil particles were moistened with 0.1% formaldehyde solution. Then, the soil particles were covered with a film for 1 day, then spread out and dried for 1 day to allow the volatilization of formaldehyde to be used again. If steam is used to sterilize the soil, it can be maintained at 65°C for 1 hour. (b) Processing of mushroom houses. Mushrooms should be kept away from dumps, pigs, cowsheds, etc. If the culture material is fermented in the mushroom house, it can be steam-sterilized in combination with pasteurization. If you do not perform secondary fermentation in a mushroom house, you can use formaldehyde to disinfect. Use 10 ml of formaldehyde per square meter and 2 g of potassium permanganate to fumigate for 12 hours. (3) Spraying pesticides evenly around the mushroom house before mushrooming can effectively prevent the occurrence of Fusarium mold. Commonly used pesticides include carbendazim, thiophanate-methyl, tetoca, and fusarium spp., etc., at a concentration of 500 to 1000 times. (d) Treatment of mushroom beds. If the incidence of Fusarium mold is large, the water spray should be stopped immediately and the mushroom and Fusarium mycelia blocks on the mushroom bed should be excavated. Mushrooms are fumigated with formaldehyde for 1 hour. Be careful not to fumigate too long. After fumigation, it is ventilated for 2 to 3 days. After the surface of the mushroom bed is dry, the pesticide is sprayed evenly. If a small amount of Fusarium mildew occurs, timely removal of mushrooms and Fusarium mycelium block, and spray pesticides evenly in the affected area. (5) Strengthen the management of mushroom houses, pay attention to ventilation and ventilation under high temperature and high humidity, and remove the mushrooms in time.
