Last Updated: 2024/11/05, Mushroom blight, also known as wilt, is caused by Fusarium oxysporum and Fusarium oxysporum. It is mainly transmitted by bacteria-carrying soil. The fungus has strong saprophytic ability and can live in soil and diseased tissues for a long time. The disease mainly affected the mushroom stalk. After infection, the medulla of the fungal stalk atrophied and turned brown. There is no difference in appearance between early infected diseased mushrooms and healthy mushrooms, but the mushroom body becomes shorter, the color of the cap is darker, and the mushroom body no longer grows, but gradually becomes "stiff mushroom". In addition, after the mushroom body is infected, the pathogen secretes toxins and destroys the mycelium.

Mushroom damping-off disease, also known as wilt disease, caused by Fusarium oxysporum and Fusarium phaseoli infection. It is mainly transmitted by contaminated soil. The fungus has strong ability to rot and can live in soil and diseased tissues for a long time. This disease mainly infects mushroom stipe, after infection stipe pith atrophy, turn brown. There was no difference in appearance between infected mushrooms and healthy mushrooms in early stage, but the mushroom body became short, the color of the cap part was darker, and the mushroom body no longer grew, but gradually became "stiff mushroom". In addition, after the mushroom body is infected, the pathogenic bacteria secrete toxins, destroy the mycelium growth or make the small buds die, thus affecting the next mushroom not to grow or die. Pink mold flakes can be seen on the surface of the culture medium.

Control measures can refer to rust spot control methods. In addition, once damping-off occurs, the following agents can be sprayed on the bacterial bed: 11 parts of ammonium sulfate and 1 part of copper sulfate are mixed, and then 56 g of this mixture are mixed with 18 kg of water, and then sprayed after stirring.
