What is green mold of Lentinus edodes?

What is green mold of Lentinus edodes? Please introduce that green mold is the most easy to occur and do great harm to competitive bacteria in the production of Lentinus edodes. If the management method is improper and the prevention and control is not timely, it will cause great losses to the production of Lentinus edodes. 1. Symptoms and conditions of green mold at the initial stage of the disease, the hyphae showed white patches, then gradually green, dark green in the later stage, dark green until soft rot. Green mold is suitable for temperature 20-32 ℃, acid environment, high temperature and high humidity is conducive to the occurrence and spread of green mold. Second, the cause of the disease (1) bacterial infection. (2) pollution caused by violation of operating rules. (3) infection of green mold caused by incomplete disinfection of inoculation tools, inoculation room and bacteria room. (4) Green mold pollution caused by bag damage. (5) High temperature and humidity are easy to infect green mold. Third, control methods 1. Select uninfected strains with high yield, high quality and strong stress resistance. 2. Heat the material bag in the furnace until 100℃ and last for 22 hours. Be sure to steam thoroughly for sterilization. Come out for inspection when the furnace temperature drops to 80%. If it is damaged, seal it with transparent tape to prevent infection of other miscellaneous bacteria. 3. The inoculation room was fumigated with 500 grams of 38% formaldehyde 18 hours before inoculation, the inoculation tools were put in a sealed inoculation box and sterilized with 15-20 grams of mushroom for 30 minutes, and the 15-20 bacteria room was fumigated with sulfur the day before, and then fumigated with 500 grams of formaldehyde. 4. Use temperature to control green mold. The best temperature for mycelial growth of Lentinus edodes is 22-24 ℃, while the infection of green mold more than 23 ℃ is the most easy to occur. Therefore, we control according to the optimal temperature of Lentinus edodes mycelium and green mold to avoid high temperature environment. The measures taken are as follows: (1) Indoor inoculation period. Evacuate the bacterial bag to reduce the stacking level. The piercing should be carried out in batches. After the piercing, the respiration of Lentinus edodes mycelium is enhanced and heat is released. When the room temperature reaches 28%, the piercing is stopped. (2) oversummer period. During the summer period, the ambient temperature is more than 30 ℃, so ventilation and cooling must be done well. If you spend the summer in the mushroom shed, the height of the shed should be up to 2.8m, and the rear wall should leave a 60-inch ventilation hole every 1.2-1.5m. The front of the greenhouse film is all lifted, and the greenhouse film is covered with grass curtains to block the sun. under the shelves of the discharge bacteria bags, dig 50 "wide and 20" deep ditches lined with plastic film. In case of high temperature ditch, spray water to the ground around the grass curtain to cool down. The floor of the shed is sprinkled with lime to reduce humidity. (3) when individual bags are infected with green mold, they should be treated in time at the initial stage, and the infected bags should be placed in a well-ventilated place below 24 ℃, or the side of the bags infected with green mold should be placed close to the cool ground or on the gutter with water, so that the mycelium of Lentinus edodes will quickly grow and eat the green mold. In the later stage of the onset of green mold, if the mushroom bag turns dark green and has no preservation value, it will be cut off with a knife and sealed with yellow mud, so that the uninfected part can grow normally and the effect is very good. 5. Formaldehyde prevention and treatment. The prevention and control of green mold of Lentinus edodes focuses on early detection and timely control. At present, formaldehyde is an effective agent to control green mold of Lentinus edodes. When the green mold patch is 1 inch in diameter, use a syringe to extract 1.5ml mixture of formaldehyde and wine at 1:1 and inject 5 needles along the plaque. When the green mold plaque is 4 inches in diameter, use a syringe to extract 4 milliliters of formaldehyde and wine mixture at 1:1 and inject 12 injections along the plaque, so that the green mold can be effectively controlled.
