Mushroom cobwebs
<h1>symptoms</h1>
Also known as Rotissporidium, soft rot. At the beginning of the disease, a layer of white cotton flocculent hyphae is formed on the bed, which is later extended to the entire bed surface, resulting in a decrease in the amount of mushrooms or no mushrooms. After the fruiting body is affected, it first develops at the base of the stalk, and then develops to the mushroom lid, and the fungus cover lesions are initially water-stained and irregular, and then covered with white villi hyphae, and gradually become brown and soft and rotten.
<h1>Regularity of occurrence</h1>
The pathogen prefers to grow in organic matter-rich, moist soils, and is prone to occur under conditions of high temperature, high humidity and high water content of the culture medium, and the conidia of the pathogen grow colonies on the surface of the cover layer. More spores are produced in the short term, which are easily transmitted by airflow, soil cover, insects and water.
<h1>integrated control</h1>
(1) Strengthen the ventilation of the mushroom room and reduce the air humidity.
(2) The soil is thoroughly disinfected with sodium dichloroisocyanurate disinfection powder.
(3) The culture medium requires full fermentation, and the sodium dichloroisocyanurate disinfectant powder is mixed in the first pile to kill the pathogenic bacteria.
(4) When it occurs locally, remove the diseased mushrooms and spray the sodium dichloroisocyanurate disinfectant powder solution for prevention and control.
