Control methods of four kinds of Diseases of Edible Fungi
1. Brown rot. Also known as vesicular disease, wet bubble disease. Mainly harmful to mushrooms, straw mushrooms, Pleurotus ostreatus and so on. The disease is caused by the pathogen of Alternaria verrucosa. Main features: the conidia and chlamydospores of verrucosporium only infect the fruiting body, not the mycelium. When the fruiting body is slightly infected, the stalk is swollen into a bubble deformity, so it is called wet bubble disease. However, the disease is different at different stages of fruiting body development. When the fruiting body is infected when it is undifferentiated, there is an irregular tissue mass, such as a hard-skinned horse, covered with white fluffy hyphae and gradually darkened.
