Pleurotus ostreatus, commonly known as oyster mushrooms, are vulnerable to several pests that can significantly impact their growth and yield. Common pests include mushroom flies, fungus gnats, cockroaches, nematodes, springtails, and even mice. These pests often lay eggs in the culture medium, where their larvae feed on the mycelium, causing it to rot and reducing the quality of the growing substrate. Adult pests are typically active at night, making them difficult to detect. Additionally, moths may also damage the mushrooms and mycelium while spreading harmful pathogens.
Throughout the entire cultivation and fruiting process, strict pest control measures must be implemented. Mice, in particular, pose a serious threat by gnawing through mushroom bags or burrowing into the growing beds, leading to significant losses in production.
To prevent infestations, maintaining good hygiene is essential. The mushroom house should be thoroughly cleaned both inside and outside, and surfaces should be disinfected using solutions like formalin, dichlorvos, or chrysanthemum-based sprays. Before sowing or inoculating, aerosol fumigation can be used to eliminate any lingering pests. All equipment, such as plastic films used for bed planting, should be properly disinfected before use and cleaned immediately after. Residues from the inoculation process should be removed promptly, and doors and windows should remain closed. Installing fine mesh screens can further help reduce the entry of insects and rodents.
If fungal contaminants like Penicillium or green mold appear on the mushroom bed, they can be treated by sprinkling lime or carbendazim powder over the affected areas. Alternatively, a potassium permanganate solution can be applied to suppress the spread of unwanted bacteria. Infected mushroom blocks should be removed quickly to prevent contamination of healthy ones. In case of insect infestation, low-toxicity pesticides such as chrysanthemum-based sprays or mushroom nets can be used effectively.
It is important to note that pesticide application should be done carefully. Spraying during the fruiting stage should be avoided if possible, and any spraying should be conducted when no mushrooms are present. This helps prevent pesticide residues from affecting human health and ensures the quality of the final product. Improper spraying can lead to deformities in the mushrooms, which can reduce their market value. Therefore, a well-planned and cautious approach to pest management is crucial for successful oyster mushroom cultivation.
