How to reduce contamination in spring cultivation of white fungus
In spring white fungus cultivation, most damage is caused by green mold, with some contamination by Rhizopus and Mucor, while Neurospora is rare. Green mold, Mucor and Rhizopus often occur at the edges of the inoculation holes in the fungus bags, or when the mycelial rings of two holes meet 9-10 days after inoculation, appearing at the front of the mycelium, and also on the bag walls. Green mold also occurs on the fruiting bodies, causing the fungus fronds to rot. Neurospora mostly occurs at the gaps where the bag openings are tied. The main causes of contamination are incomplete sterilization of the substrate bags, lax aseptic technique, holes in the bag film, impure spawn carrying contamination, or contamination of the environment.
