Brown rot, also known as wet vesicular disease, harmful fungal spore disease, pathogenic fungi is a harmful Fusarium mold.
Symptoms of brown rot: One is the germ infestation period, the mushroom bed surface formed a pile of piles of white fluffy material, the color changes from white to brown, the surface of brown beads of water seep, and finally under the joint action of bacteria Rot and odorous odor; one that is invaded when the primordium differentiates to form a block resembling a horse-shaped body, initially white, later yellow-brown, with water oozing from the surface and rot; when grown into small buds When infested, it shows malformation, mushroom stem enlargement, mushroom cap becomes smaller, white villous hyphae are attached to the surface of the mushroom body part, and then it turns brown, resulting in brown droplets; when the mushroom is infected in the late period, it not only deforms Mushrooms, mushroom surface will appear white fluffy mycelium, brown lesions later.
Brown rot pathogens mainly infect mushrooms, but mushrooms, straw mushrooms, oyster mushrooms, ganoderma lucidum, white fungus and other edible fungi are occasionally found.
Prevention methods are as follows:
(1) Disinfection of mushroom houses: Remove mushroom house waste in a timely manner and disinfect it thoroughly. Do not wait for new materials before cleaning up the waste in the previous season. The conditional mushroom house can be sterilized with steam, 70-75°C for 4 hours, and then ventilated and dried. Bed frame materials should be made of inorganic materials such as steel and plastics. After washing and disinfecting, the spores are not easy to survive.
(2) Soil-containment disinfection: First, select the soil that does not contain edible fungus waste. The medium-level soil or river soil below 20 cm in the paddy field should be selected and used after sun exposure. Appropriate to deal with the fungicide in the soil of the diseased area, such as with mushroom abundance of 2 000 times spray, spraying while turning the soil, and then build a cover film and then stuffy for 5 days before use. The promotion of river mud cover technology can effectively reduce the probability of soil contamination.
(3) Culture material pathogen treatment: In the disease area, the culture material should use fungicides, such as mushroom abundance 2000 times. When the mushroom bed appears symptoms should be promptly excavated, sprinkle with fungicide, let it dry, do not water in the ward to prevent spores, mycelium spread with the water.
