Damage to Pleurotus ostreatus and its control
All aspects of the production process of *Pleurotus ostreatus* are susceptible to microbial contamination, and prompt control measures are essential to prevent losses. Common bacterial contaminants include the following:
(1) Bacterial contamination typically occurs on the slope of the parent strain or in original strains and cultivars. These bacteria usually show mild symptoms at first, but they can develop rapidly, often becoming visible within 10 to 24 hours after inoculation. To manage this, it's crucial to sterilize all inoculation tools by wiping them with alcohol and then flaming them. Additionally, the culture medium should be properly sterilized according to standard protocols to reduce the risk of contamination.
(2) *Penicillium* and *Trichoderma* are common fungal contaminants that affect both the original strains and cultivated varieties. Once infected, the mycelium may grow aggressively, covering the surface of the medium. *Trichoderma*, on the other hand, tends to appear during the fruiting stage. When either of these fungi is detected, immediate action must be taken to remove the contaminated material and prevent further spread.
(3) During the hot summer months, *Streptomyces* is more likely to occur, producing a large number of orange-red powdery spores. Infections caused by *Neurospora* should also be addressed quickly. Contaminated bottles must be thoroughly cleaned and soaked in a 0.05% potassium permanganate solution or sterilized before being reused. Maintaining strict hygiene throughout the entire cultivation process is key to ensuring successful mushroom production.
