How does edible fungus produce penicillium disease to do?
How to do when penicilliosis occurs in edible fungi.
There are more than 350 species of edible fungi known in China, most of which belong to basidiomycetes, including Lentinus edodes, straw mushrooms, mushrooms, fungus, Tremella, hericium Erinaceus, bamboo shoot, Tricholoma matsutake, Tricholoma, red mushrooms and boletus; a few belong to ascomycetes, including Morchella, saddle, truffle and so on. The above fungi grow in different regions and different ecological environments.
Control methods of edible fungus Penicillium disease:
Pay attention to environmental hygiene, keep the surrounding of the culture room and the cultivation land clean, and dispose of the waste in time.
Inoculation rooms and mushroom rooms should be cleaned and disinfected in accordance with the regulations; operators must ensure thorough sterilization during seed production, and bagged bacteria should be handled gently in the process of handling to prevent plastic bags from breaking.
Regular inspection, found that bacteria are contaminated should be eliminated in time, never sow diseased bacteria. If Penicillium occurs on the mushroom bed culture material, it can be ventilated and dried in time, and the room temperature can be controlled at 20: 22 ℃. After the miscellaneous bacteria are restrained, the routine management can be resumed.
Adjust pH, increase pH appropriately, add 1%-3% quicklime or spray 2% lime water to inhibit the growth of miscellaneous bacteria. Medicament mixing material, with 0.1% weight of dry material methyl topiramate mixing material, the prevention and control effect is better.
Attention should also be paid to ventilation in mushroom houses and mushroom farms to avoid high temperature and humidity; when the disease occurs locally, it can be smeared with 5%-10% lime water or sprinkled with lime powder, or it can be dug out first, and then sprayed with 3%-5% copper sulfate solution to kill bacteria.
Prevention and cure method
① conscientiously does a good job in disinfection and sterilization of inoculation room, culture room and production place, keeps the environment clean and hygienic, strengthens ventilation and ventilation, and prevents the spread of diseases.
② adjusted the appropriate pH of the culture medium. The culture materials of cultivated mushrooms, Pleurotus ostreatus and Lentinus edodes can be adjusted to slightly alkaline with 1% Murray and 2% lime water. After mushroom picking, lime water was sprayed to stimulate the mycelium growth of edible fungi and inhibit the occurrence of penicillium.
The local disease of ③ bag can be injected with 15% formaldehyde solution, and when penicillium occurs, it can be washed with lime water. 1% carbendazim, 0.5% Duofengnong, 0.1% Shibaogong and 0.1% prohydantoin solution can be used to control the disease on mushroom bed.
