Detailed Guide to Identifying and Controlling the Main Diseases and Pests of Oyster Mushrooms

The most serious damage is contamination by foreign molds. Common contaminating molds include Trichoderma, green mold, yellow mold, Rhizopus, and others. The main control methods are: choose materials free of mold, compost and ferment the substrate and sterilize it, strictly disinfect the cultivation site, and promptly remove any contaminated material. Provide proper ventilation to prevent excessively high temperatures and humidity.

Oyster mushroom cultivation also frequently shows physiological disorders: ① Partial death of small mushrooms: when there are too many small mushrooms, some will die, mainly from "starvation" due to insufficient nutrients; spraying water too early or excessively high humidity can also cause small mushrooms to die. ② Big-foot mushroom: often caused by poor ventilation and excessively high carbon dioxide concentration. ③ Withering of young mushrooms: mainly due to the substrate being too dry or the air humidity being too low.

The main insect pests in oyster mushroom cultivation are mushroom flies and others. Generally, the methods used to control foreign molds can also control mushroom flies and other pests fairly well. At the same time, try to prevent plastic bags from tearing during handling.
