The most common and harmful bacteria of edible fungi are more than 20 species of Trichoderma, Streptomyces, Mucor, Aspergillus, Penicillium, and bacteria.
Trichoderma. Trichoderma commonly known as green mold, can almost harm all the edible fungi, its damage to edible fungi as follows: (1) pollution culture materials and edible fungi for nutrition and space; (2) secrete cytochrome kill, kill the host; ( 3) When the mycelium of the trichoderma touches the host mycelium, the host mycelium is wound and cut off. Prevention: Conduct comprehensive prevention and control work. (1) The culturing room and cultivation place should be kept at a low temperature, the relative humidity of the air should be controlled at about 85%, and be kept clean and well-ventilated; (2) In the event of the occurrence of trichoderma, it should be immediately ventilated and dehumidified. Injection of 2% aldehyde solution or 30%-5% carbonic acid inhibited the expansion of Trichoderma. Some infected and mature bacteria barrels can be used to excavate contaminated parts, and lime powder or lime sulfur or Bordeaux mixture etc. can be applied to the treated parts. It can also be treated with fungicides such as carbendazim, application of protection and thiophanate-methyl. If 50% carbendazim 1000 spices can prevent the occurrence of Trichoderma, but it should not be used in Hericium, edible fungus, white fungus on carbendazim.
