(1) Bacteria mostly occur on the slope of the parent species, and the original species and cultivars are relatively light. Bacterial contamination is characterized by rapid growth, which can be demonstrated within 10 to 24 hours after inoculation. Control methods: First, the inoculation tool must be rubbed with alcohol and flame sterilized. The second is to sterilize the medium in accordance with regulations.
(2) Penicillium and Trichoderma Penicillium hazards are common to original species and cultivars. After the infestation, the mycelium grew to grow and cover the surface of the medium. Trichoderma occurs during fruit body formation. When these two kinds of bacteria appear, they should be removed in time.
(3) In the summer high temperature season, Streptomyces is the most prone to occur, and produces a lot of orange-red powdery spores. The strains contaminated with Neurospora are to be eliminated in time; the bottles must be thoroughly cleaned and soaked in 0.05% potassium permanganate water or sterilized before use.
