How to Prevent and Control Mucor on Reishi Mushroom? A Detailed Guide to the Latest Control Methods
Mucor on reishi mushroom is a common disease caused by Mucor fungi. Mucor, commonly known as hairy mold, is a common contaminating fungus in mushroom spawn. It grows quickly and occurs widely, and it favors high temperature and high humidity. Under conditions of high temperature and high humidity with poor ventilation, the incidence rate is very high. Now let us take a look at the prevention and control methods for Mucor disease on reishi mushroom!
Characteristics of Mucor Outbreaks on Reishi Mushroom
Mucor fungi often live on organic matter. Mature spores spread through the air, and when temperature and humidity are suitable, they germinate hyphae on organic matter, especially in high-temperature and high-humidity environments, where they grow rapidly. During the spawn growth process, incomplete disinfection and sterilization of the culture substrate and inoculation tools, failure of workers to strictly follow aseptic operation requirements, or damp cotton plugs on spawn bottles and spawn bags can all cause contamination. If the cultivation room remains poorly ventilated for a long time, the incidence rate is high.
Harmful Characteristics of Mucor on Reishi Mushroom
Mucor can secrete organic acids and toxins that inhibit the growth of reishi mushroom hyphae. After the culture medium is affected, the hyphae appear grayish-white, relatively thick and strong, and grow quickly. In the later stage, many small yellow-white round granules form at the tips of the aerial hyphae, which gradually turn black. Mucor competes with reishi mushroom hyphae for nutrients and water. Mucor has a very strong ability to decompose proteins and strong resistance, inhibiting hyphal growth.
Prevention and Control Measures for Mucor on Reishi Mushroom
1. Do a good job of environmental sanitation, and keep the inoculation room and inoculation box clean, dry and strictly disinfected.
2. Choose a suitable cultivation site, away from livestock manure and other materials containing organic matter.
3. Select fresh, dry raw materials free of mold as the culture substrate. When mixing the substrate, control the proportion of wheat bran and rice bran to within 10%.
4. When mixing the substrate, use 25% carbendazim at 0.2% of the dry material weight, or thiophanate-methyl at 0.2% of the dry material weight.
5. Strengthen cultivation management, provide ventilation in a timely manner, maintain appropriate temperature and humidity in the cultivation room, keep the environment clean and sanitary, and destroy the living environment of the pathogen.
