Disease symptoms Fusarium mildew, also known as brown rot, white rot, wet bulb disease, leeches, etc., the disease is caused by a pathogen called Fusarium. Fusarium is a kind of soil fungus. In the cultivation of Agaricus bisporus, Fusarium oxysporum mainly comes into the mushroom house with covering soil, which occurs in the high temperature, high humidity and poor ventilation and ventilation. The temperature above 17°C is suitable for the disease. .
Prevention:
First, the mushroom shed management mushroom shed should be selected in a non-polluting place. The mushroom shed is strictly sterilized. The cultivating material must be sterilized before entering the house or before the culturing end of the culturing material exits the house. The culturing material is subjected to secondary fermentation. In addition, before the mushroom sheds that have been infected for the first time, they should be pasteurized at 60°C for 10 hours, and then tarred for 2 days before being re-studded. Cultivation and processing facilities can be used after disinfection. The diseased mushroom shed can remove the mushroom and clear the material surface, and adopt the open cover type to make the shed temperature as low as possible. If the temperature is lower than 13°C, it can prevent the bacteria from harming. The bacterial bed contaminated by bacteria should be sterilized with 75% alcohol.
The second is that strict disinfection of soil with soil cover is the survival site for Fusarium mold. Cover soil can not use topsoil, should choose a depth of less than 20 cm deep soil, take soil after exposure in the hot sun 3-5 days after the use of 75% alcohol sterilization.
The third is to strengthen the management once the disease occurs, should immediately stop spraying water, increase the ventilation of the mushroom house, in order to reduce the relative humidity in the mushroom house, the temperature dropped to 15 degrees below, remove all the mushrooms. When the disease is severe, it is necessary to remove the infected soil, replace the new soil, and burn the mushrooms to disinfect.
