C. sclerotiorum, also known as the fork-like charcoal bacterium, is a parasitic fungal pathogen that has become increasingly problematic in recent years. It primarily affects the cotyledons of Coprinus comatus during its growth stage. The fruiting body of this fungus resembles chicken feet and is commonly referred to as "chicken claw." When the mycelium of Coprinus comatus grows, it can be infected by the C. sclerotiorum mycelium present in the soil. These two mycelia intertwine, leading to a deformation that results in the formation of the chicken claw mushroom.
When the disease occurs, the affected areas turn dark brown, with a sharp base and a strong connection. The C. sclerotiorum mycelium competes with the Coprinus comatus mycelium for nutrients, inhibiting its growth and causing severe damage, such as cut-off mushrooms or even total failure in production. This disease is most common in late autumn, early summer, and after the second flush of mushrooms. High temperatures, high humidity, and poor ventilation create ideal conditions for its development. The source of infection usually comes from contaminated substrates or cover soil.
To prevent and control this disease without using harmful chemicals, several measures can be taken. First, use high-quality pure cultures to avoid contamination. Second, ensure all raw materials are fresh, dry, and free from mold. Third, add 0.1% to 0.2% of 50% carbendazim or Keshiwang to the culture medium to inhibit bacterial growth. Fourth, ensure thorough composting and consider using clinker cultivation. Fifth, handle the cover soil carefully, and disinfect if necessary. Sixth, during high-temperature seasons, avoid using bagged soil as a cover to prevent cross-infection. Seventh, maintain proper cooling, dehumidification, and ventilation in the mushroom house, and avoid water accumulation. Finally, when the disease appears, remove the infected areas promptly to prevent spore spread, and treat them with environmentally friendly agents.
Second, rot disease is a common bacterial infection that poses a serious threat to mushroom crops. Infected fruit bodies initially show brown spots, which progress to blackened caps and eventual decay, leaving only the stipe. This disease is easily triggered by high temperature, high humidity, and poor air circulation, especially during the summer season. To manage it without chemical pollution, the mushroom house should be disinfected with lime water or caustic soda before inoculation. The moisture level of the cover soil and the air humidity should be slightly reduced. At the onset of the disease, agricultural-grade streptomycin (at a concentration of 100–200 mg per 1000 ml) can be used for prevention and treatment. Proper care and hygiene practices are essential to prevent further infections.
Third, brown spot disease typically appears in the early stages as brown patches on the stem and cap of the fruiting body, which gradually expand and cause the entire mushroom to turn brown. This condition is often triggered by excessive moisture in the cover soil or improper watering during the fruiting phase. It is more prevalent during reverse-season cultivation in the summer months. For non-polluting prevention and control, the moisture content of the cover soil should not be too high, and the soil should remain loose and not sticky. It is advisable to avoid spraying water directly on young mushrooms during the fruiting period. If environmental humidity is high, increase ventilation and dehumidification efforts to reduce the risk of disease occurrence.
Viral Transportation Medium Tube
Uses: used for the detection and sampling of influenza, hand, mouth, foot and other epidemic diseases
Inspection principle:
The combination of multiple antibiotics has broad-spectrum antibacterial and antifungal effects;
