Although Oyster mushroom owns strong resistance to sundry fungus contamination, however, the widespread adoption on raw material cultivation brings about sundry fungi that massively propagate in high-temperature, high-humidity, partial acid or poorly ventilated circumstances, which directly and dramatically leads to the reduction in production or production failure. Common mischievous sundry fungi are Blue Mold, Trichoderma, Mucor, Rhizopus and others. Mushroom farmers have to adopt comprehensive control measures to avoid their occurrences.
The efficient one is to cultivate Oyster mushrooms and sow in due time. Low temperature makes no contribution to the growth of mould, hence choose to sow on low temperature. The spring sowing period could be moderately brought forward and the autumn period could be properly delayed. Theoretically, the optimal temperature on the spawn growth of Oyster mushroom is 25 degrees, which reveals proper substrate sterilization. However, in raw material cultivation, it is needful to avoid the suitable growth period on mould (Generally in 25-30 degrees). Practice has proven that the spawns of Oyster mushroom grow fast in under 20 degrees, the sowing therefore indicated safe.
