With the expansion of the cultivation scale of edible fungi, the disease of Coprinus comatus has also been on the rise year after year. The symptoms and prevention methods of the disease are described as follows:
1. C. sinensis is carbonicidal fungus: it is a pathogenic fungus that mainly occurs in the growth stage of cotyledons of coprinus comatus. Its fruiting body resembles chicken feet commonly known as “claw clawâ€. When the coprinus comatus mycelium grows, it is disturbed by the mycelium in the soil, and the two combine with the kinks to become metamorphosis and grow into chicken claw mushroom. When it occurs, it is dark brown, with a sharp, base connected, its mycelium and Coprinus coussa compete for nutrients and inhibit the growth of Coprinus comatus mycelium, resulting in severe cuts in Coprinus comatus, or even out of production. In the late spring and early summer and after the second tidal mushroom, many of the chicken claw claws often occur. It is dark, high in temperature, high in humidity, poor in ventilation, and prone to be induced by the bacteria bed. Pollution-free prevention and control: First, the use of high quality pure strains. The second is to add 0.1% to 0.2% of 50% carbendazim to the culture medium to inhibit the growth of various bacteria. Third, the accumulation of fermentation should be thorough, use caisson to be careful, if necessary, disinfection. Fourth, in the season when the temperature is high, it is best not to take the bag and cover the soil to produce mushrooms to avoid mutual infection. Fifth, attention should be paid to cooling, dehumidification, increasing ventilation, and avoiding stagnant water in the mushroom shed. Sixth, once the chicken claws are found, they should be excavated in time to prevent spores from maturation and spread, and be treated with pollution-free drugs.
2, rot disease: caused by bacteria, damage heavier. The infected fruiting body was brown at first, and the cap was black and rotted. The disease is easily induced by high temperature, high humidity and poor ventilation, and the incidence is high during the summer season when it is back-seasoned. Pollution-free prevention and control: Disinfect the mushroom shed with lime water and caustic soda before feeding. Air humidity and cover soil moisture content should be slightly lower. At the beginning of the disease, streptomycin (100-200 mg/100 ml) can be used for prevention and treatment. Remove mushrooms in time to prevent infection.
3. Brown spot: In the early stage of disease, brown plaques appeared on the stipe and cap of the fruit body and gradually expanded, eventually causing the whole mushroom body to turn brown. The humidity of the soil cover and the environment is too large and it is easy to induce the disease when the water spray is improper during fruiting, and it is easy to occur during the summer season when it is cultivated in reverse season. Pollution-free prevention and control: The moisture content of the covering soil during the fruiting period should not be too high. During the fruiting period, spraying water on the young mushrooms should be avoided as much as possible. When the humidity is high, ventilation and dehumidification should be enhanced.
4, brown scale mushroom: the performance of the surface of the bacteria on the surface of the scales, and brown, is a physiological disease. The main reason is that the light is too strong and the humidity is low. Non-pollution prevention and control: During the fruiting period, the shading management should be done so that it grows under weak light and avoids strong light. The relative humidity is between 80% and 85%. If it is lower than 70%, water must be sprayed to the wall and the ground in time.
