1. Trichoderma. After the culture material was infested with Trichoderma, white cotton flocculent hyphae were firstly produced, and then expanded from the center of the mycelial layer to the periphery with a light green color, and finally turned to a dark green color, and powdery conidia appeared.
Prevention methods: First, keep the site and tools clean, often sterilize culture rooms, cultivation fields, tools, etc. to keep the surrounding environment clean.
The second is to sterilize the culture materials. When preparing the culture materials, add 0.1% of 50% wettable carbendazim according to their dry weight, and also use 0.1% thiophanate-methyl compound.
The third is chemical control. When the Trichoderma has invaded the material, it should be gently excavated, and then sprayed and painted with 800 times the 50% carbendazim WP, 200 times the Kemodulin or spray. 10% lime water control.
The fourth is to eliminate the contamination of the bacteria plate, if it is particularly serious infection by Trichoderma, not easy to control, can be buried or burned bacteria plate, anti-Trichoderma spores spread, spread.
2. Streptomyces. Streptomyces is also called red bread mold. This kind of mildew grows fast. The beginning of the disease was white and sticky. When the conditions are suitable, the orange bread forms in 5-10 days. When it is serious, the inoculation point or the damage of the cultivation bag grows to the outside of the bag, forming a huge orange colony. After the touch, the spores can be easily dispersed into the air.
Prevention methods: First, do a good job in the cultivation of the disc production site environmental health, regular disinfection, do not give opportunities for growth and transmission of Streptomyces.
The second is strict sterilization, inoculation, culture materials to be completely sterilized, inoculated personnel strictly aseptic operation.
The third is to pay attention to the humidity, should pay attention to the ventilation of the training room, row tide, reduce indoor humidity, if necessary, in the cultivation of indoor and outdoor bacteria and sprinkle lime powder to wet.
Fourth, drug treatment. When aneurysm occurs locally in the culturing chamber, the sprayer and other medical equipment are most directly sprayed with bactericidal drugs directly to the pollution department and the culture room, because the surface spraying drug is not good at this time, and it also causes conidial proliferation, pollutes the environment, and causes more Serious pollution. The mushroom room can be used for space disinfection with 800 times of liquid dominance. The emerging Cladosporium was smeared with diesel oil, and then air-sheltered and sterilized with smoke-disinfectant A Xiao Ling or chlorothalonil to control the spread of pathogens.
