Safe Prevention and Control Techniques for Edible Mushroom Diseases, Pests, and Weeds

    Neurospora, also known as pink mold (fungus), is mostly red or pink and readily occurs on wheat-grain spawn and cooked substrate. It is more likely to occur under high temperature and high humidity. The typical symptoms are: when a mushroom bag is infected, white granular colonies first appear on the local substrate inside the bag, then become sparse and fuzzy; after one day, large numbers of conidia are produced, appearing orange-red. If it is not removed promptly or the removal method is incorrect, it will cause contamination throughout the entire environment.
     Disease prevention and control measures: (1) Do a good job of environmental sanitation, keep the cultivation site clean and dry, with no accumulation of waste materials or contaminated materials. The substrate should be fresh and dry, and clean water should be used for mixing the substrate.
    (2) Sterilize and alkalize the substrate: add 0.5% lime powder to the material to increase the pH of the material, and spread lime on the soil for disinfection treatment.
    (3) Purify and disinfect the air at the inoculation and spawn-running sites.
    (4) Keep the shed cool, ventilated, and dry, with the temperature controlled at around 25°C. If the floor is damp, lay a thick plastic sheet to isolate moisture.
    (5) Mushroom houses and cultivation sites should undergo rice-upland crop rotation or be left vacant for a period of time.
     Prevention and control of Neurospora disease requires early detection and early handling to prevent spread. Once a Neurospora-infected mushroom bag is found, immediately wrap the contaminated bag with gauze soaked in disinfectant and destroy it. If Neurospora appears on part of a mushroom bag, drip diesel oil onto the conidial masses or wipe with diesel oil to prevent the spread of Neurospora. If Neurospora occurs in the later stage of spawn running in the mushroom bag, the affected bag can be buried in soil with poor air permeability at a depth of 30-40 cm. After 10-20 days of oxygen-deprivation treatment, the disease can be effectively reduced.
