Beware of Apocynidium tuberculosis
Agrocybe aegerita is favored by consumers because of its crisp texture and rich nutrition. In recent years, the production has developed rapidly. But in the two years, the incidence of viscomycosis was more serious, which caused a certain loss of production. The occurrence of myxomycetes should be prevented during the cultivation process of Agrocybe mirifica in order to ensure the healthy growth of Aketone mushrooms. First, the cause of the disease and harm symptoms 1, the cause of the disease. 1 Myxomycetes are suitable for growing in places with rich organic matter and humid environment. Especially under conditions of high temperature and high humidity, the ventilation of the cultivation room is poor, which is most conducive to the germination and growth of myxomycotina, and its nutritional colonies are rapidly expanding. 2Use water or air with slime spores. 3 culture material infected bacteria. Myxomycetes are omnivorous organisms. Bacteria, organic matter, spore pieces and spores of Agrocybe aegerita are all nutrient sources of Myxomycetes. In particular, bacteria are a good source of nutrients for myxomycetes. If the Agrocybe nobilis culture material or fruit body is infected by bacteria, slime can easily occur. 2, damage symptoms. Myxomycetes mainly grow on the surface of the bacterial bag culture material and bacteria bags inside and outside the film after the bud mushroom has opened the fruit buds, and it often occurs in a single place where several bags and dozens of bags are spread. A training room occurs everywhere or a dozen or twenty places. The growth of tea-fermented mycelium, which is harmed by this slime bacterium, is suppressed or gradually eliminated. There are a large number of bacteria and nematodes in the culture materials, and the fruit bodies are harmed into soft rot and moldy. Second, comprehensive prevention and control technology 1, preventive measures. 1 Use high-quality bacteria. To use pure, non-polluting, odor-free, strong viability and moderate strains of bacteria, strains bottle tampon should be dry and pollution-free. The water content of strains should be moderate and should not be too dry or wet. 2 The culture material should be sterilized. The raw and auxiliary materials to be cultivated such as sawdust, sphagnum powder, cottonseed husk, bran, etc. should be exposed to the sun before use. The cotton shells should be soaked with 0.5% to 1% quick lime for 24 to 36 hours. Sawdust stacking is best for 10 to 15 days, adding 0.3% to 0.5% when stacking, and no use of sawdust for cultivation. 3 pay attention to strengthen ventilation and ventilation of mushroom house, especially in high temperature and humidity. The suitable growth temperature for Agrocybe aegerita fruit body is 15-28°C, the optimum temperature is 20-25°C, and the humidity is 85%-95%. When the temperature exceeds 25°C. Mushroom ventilation is best for early, middle and late times. 4 to pay special attention to the use of flowing clean water or tap water spray mushroom buds, to reduce the water source bacteria, slime bacteria and other pathogens. 5 After the collection of bacteria bags to remove debris. At the same time, to stop the water spray, open the windows and ventilate for 5 to 7 days, let the mycelium rejuvenate and then spray water Choi Lei mushroom. 2, after the onset of treatment. Once slime grows in the cultivation bag, spray water should be stopped, increase ventilation, and sprinkle lime powder around the culture room and aisle. In the early stage of disease, if the mushroom is to be harvested after the fruiting body is harvested, it is sprayed once or twice with 50% carbendazim WP or 70% thiophanate-methyl plus 100-200 IU streptomycin 1:500. Secondly, the viscous fungus that grows on the surface of the bacteria bag and the inside and outside of the mouth of the mushroom bag can be controlled and sprayed.
