Control of Fusarium Wilt of Edible Fungi

Also known as death blight, is a physiological disease. It mainly harms mushrooms, Pleurotus ostreatus, Pleurotus ostreatus and so on. The main characteristics are as follows: after the mushroom bud is formed, the disease can occur in fruiting bodies of different sizes. Stop growing after the disease, yellowing, gradually shrinking, softening, drying, and finally withered or rotted.

Etiology: the occurrence of the disease is the result of physiological obstruction. The main reason is that the culture material is too dry after the formation of the primordium, which makes the mushroom bud wither; or the mushroom is too dense; the nutrition supply is not enough, so that part of the mushroom dies; or the mushroom room temperature is too high, the temperature is too high, the ventilation is not good, and the lack of oxygen is caused by the excessive content of carbon dioxide in the air; and it is also caused by accidentally bumping the small mushroom bud or producing too much mushroom when picking mushrooms.

Prevention and control measures: when the fruiting body appears wilting, we should first find out the cause of the disease and take corresponding measures. Do not spray in the mushroom room after mushroom production, otherwise it is easy to cause drug damage. In particular, Pleurotus ostreatus and Pleurotus ostreatus should not be sprayed with dichlorvos during mushroom production.
