Symptom Identification and Control Methods of Soft Rot in Edible Fungi

Mushroom Cultivation 0 views
Damage symptoms: White bead-like mycelial networks first appear on the surface of the casing soil on the bed. If not treated promptly, they quickly spread and turn water-red. Infection of the fruiting body starts from the stipe and extends to the cap, initially appearing water-soaked, then gradually turning brown, softening, and eventually rotting. Classification: A fungal disease caused by Verticillium dendroides. Disease characteristics: The casing soil carries the pathogen, which spreads mainly through airflow and water droplets in the mushroom house. Control methods: Strictly disinfect the casing soil to cut off the source of infection. When it occurs locally, spray a 2%-5% formaldehyde solution or 800 times

Classification: A fungal disease caused by Verticillium dendroides

Disease characteristics: The casing soil carries the pathogen, which spreads mainly through airflow and water droplets in the mushroom house.

Control methods: Strictly disinfect the casing soil to cut off the source of infection. When it occurs locally, spray a 2%-5% formaldehyde solution, or 800 times diluted 40% carbendazim, or 800 times diluted thiophanate-methyl. You can also spread 0.2-0.4 cm thick lime powder on the surface of the affected bed. At the same time, reduce watering on the bed surface, strengthen ventilation, and lower the temperature and humidity.
