Safe Prevention and Control Technology for Diseases, Pests and Weeds of Edible Fungi

Alternaria is also called Neurospora (bacteria), mostly red or pink, easy to occur in wheat seed and cooked culture medium, more likely to occur under high temperature and high humidity conditions, typical symptoms are: when the bacteria bag is infected, white granular colonies are first seen on the local culture medium in the bacteria bag, and then they are sparse and fluffy. A large number of conidia are produced one day later, showing orange color. If they are not cleaned up in time or the cleaning method is wrong, it will cause infection of the whole environment.

Disease control measures: (1) do a good job of environmental sanitation, keep the cultivation environment clean and dry, no waste and pollutant accumulation. Cultures should be fresh, dry and mixed with clean water.

(2) Substrate sterilization alkalization treatment, adding 0.5% lime powder to the material to improve the pH value of the material, soil lime disinfection treatment.

(3) Purify and disinfect the air of inoculation and bacteria transmission sites.

(4) Keep the shed cool, ventilated and dry, and control the temperature at about 25 ° C. If the ground is wet, a layer of thick plastic cloth should be laid to isolate moisture.

(5) Mushroom houses and cultivation sites should be rotated by paddy and upland or vacant for a period of time.

The disease of Alternaria sp. should be discovered and treated early to prevent its spread. Once streptospora bags are found, immediately wrap the contaminated bags with gauze soaked in disinfectant and destroy them. If Alternaria is present in the bacterial bag, diesel oil can be dripped on the conidia or rubbed with diesel oil to prevent the spread of Alternaria. When Alternaria occurs in the later stage of bacterial growth, the affected bacterial bag can be buried in 30~40 cm deep and poorly ventilated soil. After 10-20 days of hypoxia treatment, the disease can be effectively alleviated.
