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. Almost all edible fungus can be harmed, and its harm to edible fungi is as follows: (1) Contaminated culture material competes with edible fungi for nutrition and space; (2) Secretin kills and kills host; (3) Trichoderma mycelia contact When the host mycelium is reached, 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. Streptomyces Streptomyces spp., commonly known as pinkish pink disease and red baker's mildew, is a common germ in the production of edible fungi and can contaminate all edible fungi. It is a tenacious, fast-growing mold of airborne fungi. An orange-red or pink mold layer forms. Prevention and treatment: Try to avoid hot, humid summer high-temperature production, pay attention to doing a good job of environmental health. Once the orange-colored massive conidia cluster appears, carefully wrap it with a damp cloth or wet paper, immerse it in the liquid or bury it deeply, and do not use a sprayer to spray the bacteria directly to prevent spores from scattering. Formaldehyde, kerosene, or diesel, and then bandaged with a film, can kill mold. In the late stage of bacterial infection, the infected bacterial bags can be buried in a soil with a poor 30-40 cm deep air permeability. After 10-20 days of hypoxia treatment, the disease can be reduced to produce mushrooms. Sterilizers such as carbendazim and Shi Bao Gong can control the growth of Trichoderma spp. Aspergillus and Penicillium Aspergillus commonly known as yellow mold, green mold, black mold and so on. There are many types of Aspergillus. The colony of Aspergillus niger is black loose fruit-like; Aspergillus flavus is yellow, yellow-green, and finally brown green; Aspergillus niger is gray-green after the first white; Penicillium, its many species, colonies are gray-green, yellow-green or blue Powdery mildew layer. Aspergillus and Penicillium are common bacteria. They compete with edible fungi for nutrients and water, and secretoryin inhibits the production of edible fungi. Prevention: Strengthen the ventilation of the culturing room, lower the temperature, reduce the relative humidity of the air, and reduce the damage. The local occurrence can be washed with 5-10% lime water. For other control methods, reference can be made to the control of Trichoderma spp. Collection Pouch,Fluid Collection Pouch,Urology Collection Pouch,Disposable Fluid Collection Pouch ShaoXing SurgeCare Medical Products Co., Ltd. , https://www.sxsurgecaremedical.com
