Edible fungus spot disease typically appears in the early stages of infection, where the surface of the mushroom cap becomes uneven, followed by round or irregular lesions. When humidity is high, the affected mushrooms on the growing bed may develop white fruit bodies, and in severe cases, the gills can stick together. To prevent and manage this issue, it's essential to use **pesticides** promptly.
The disease spreads primarily through contaminated soil that enters the mushroom house and is further transmitted via air currents. High relative humidity, especially above 95%, creates favorable conditions for the disease to thrive.
To control the spread of the disease, consider the following measures:
1. Once the disease is detected, improve ventilation in the mushroom house to reduce humidity and limit the spread of the infection.
2. Remove infected mushrooms immediately and dispose of them properly to avoid contamination of healthy crops.
3. In the early stages of the disease, apply one of the following fungicides: a 500-fold dilution of 50% carbendazim wettable powder, a 600-fold dilution of 70% thiophanate-methyl wettable powder, or a 600-fold dilution of 60% propiconazole emulsifiable concentrate. These treatments are effective in controlling the disease when applied early.
By implementing these practices, you can significantly reduce the impact of the disease and maintain the quality of your edible fungi crop. Always follow the manufacturer’s instructions when using any chemical products, and ensure proper safety measures are in place during application.
