What are the common diseases of the tea tree mushroom? Detailed explanation of prevention and control methods

Mushroom Cultivation 0 views
The tea tree mushroom is a rare mushroom variety that has been very popular in domestic and international markets in recent years, but because pest and disease problems occur relatively often, growers often fail to accurately identify the symptoms and pathogens and blindly use chemical pesticides, resulting in damage to the mushroom bodies and poor cultivation returns. The symptoms, pathogens and control measures of common infectious diseases are introduced below: 1. Brown rot disease The affected fruiting bodies stop growing, and the caps and stipes rot and give off a foul odor. The pathogen is Mycogone perniciosa, which mainly spreads and causes disease through contaminated water or hands, tools, etc. that have come into contact with diseased mushrooms

The tea tree mushroom is a rare mushroom variety that has been very popular in domestic and international markets in recent years, but because pest and disease problems occur relatively often, growers often fail to accurately identify the symptoms and pathogens and blindly use chemical pesticides, resulting in damage to the mushroom bodies and poor cultivation returns. The symptoms, pathogens and control measures of common infectious diseases are introduced below:

1. Brown rot disease The affected fruiting bodies stop growing, and the caps and stipes rot and give off a foul odor. The pathogen is Mycogone perniciosa, which mainly spreads and causes disease through contaminated water or hands, tools, etc. that have come into contact with diseased mushrooms. Control measures: (1) Carry out good disinfection of the mushroom shed. (2) The water used during the fruiting period must be clean, and attention should be paid to ventilation and air exchange. (3) Promptly pick and destroy affected mushrooms, increase ventilation, and reduce humidity inside the shed. (4) Spray the mushroom bags with a 50-fold streptomycin solution to sterilize them and prevent recurrence of the disease.

2. Soft rot disease The affected mushroom bodies bend, soften and collapse, and finally wither and die, becoming shriveled and stiff. The pathogen is Fusarium solani, and the disease incidence is high under conditions of high temperature and high humidity. Control measures: (1) Sun-dry the raw materials thoroughly, and sterilize the mushroom bags completely. (2) Choose to inoculate when the temperature is low. (3) Before opening the bags, spray with a 1000-fold dilution of 50% dichlorvos emulsifiable concentrate to sterilize; after opening, control the temperature at 23°C-25°C and the relative humidity of the space at 80%. (4) If the disease occurs at the young mushroom stage, spray the clear supernatant of limewater with a pH value of 8, or spray with a 1500-fold dilution of 20% triadimefon emulsifiable concentrate.

3. Damping-off disease The stipes of the diseased mushrooms shrink and dry up, do not develop, and wilt, but do not rot. The pathogen is Fusarium solani. The disease is likely to occur when the substrate quality is poor or when the loading and sterilization time is long. Control measures: (1) The substrate must be fresh and of high quality. (2) Sterilize promptly after bagging. (3) During the mycelial growth period, prevent high-temperature damage to the mycelium and prevent direct sunlight. (4) Once the disease occurs, harvest early and promptly dig out the substrate at the affected site, then spray medicine for disinfection.

4. Mold rot disease The affected fruiting bodies become moldy, turn black, collapse and rot, and have an ammonia-like odor. The pathogen is Trichoderma viride, and the disease mostly occurs because the substrate sterilization is not thorough. Control measures: (1) Pay attention to disinfection of the mushroom shed and the surrounding environment. (2) Strictly carry out aseptic operations. (3) After the disease occurs, promptly remove the diseased bags for disposal, and do a good job of disinfecting the mushroom shed.
