What to Do When the Surface of Oyster Mushroom Substrate Turns Black? Cause Analysis and Control Methods
The main causes of blackening on the substrate surface and the control methods are: (1) Oyster mushroom mycelium soaked in water for a long time causes rot and blackening. In this case, the condensation water on the substrate surface should be absorbed and dried promptly. If it is grown on beds, excess water at the bottom should also be absorbed and dried promptly. (2) Contamination by foreign microorganisms and breeding of insect pests cause blackening. When blackening occurs, pests must be controlled or the affected part dug out promptly to prevent it from spreading.
