Three Kinds of Mushroom Bacteria Control Measures

1. Trichoderma is also called green mold. When Trichoderma spp. Invaded the medium of mushroom, it was white cotton floc at the beginning and green at the later stage. If the strain is harmed by Trichoderma, it must be scrapped. There is no ideal control drug for Trichoderma so far. Creating an ecological environment suitable for the growth of mycelium of mycelium and unfavorable to the propagation of Trichoderma is the fundamental measure to control the hazard. In the event of a hazard of Trichoderma, immediately ventilate and dehumidify to suppress the expansion of Trichoderma. After the fungus is infected with mold, the injection of liquid can be used to inhibit the expansion of Trichoderma. The commonly used liquid is 5% stearic acid solution, 2% formaldehyde solution, 50% carbendazim 200 times, pH value. 10 lime water and so on. Lime is added to the pollution and the control effect is also good.

2. The growth stage of Trichoderma was villous, white or gray at the beginning of growth, and it was pink or yellow at the late stage of growth. It is mainly transmitted by conidia. The temperature of the mushrooms was controlled to be below 20°C. The growth of the cysts was slow and the pollution could be reduced. At the same time, the control of the humidity in the germination site can effectively prevent the occurrence of Streptomyces. Strains were found to be contaminated during the production of the fungus bag, and diesel oil was dripped onto the conidial spore mass to prevent the proliferation of Streptomyces. After the fungus bag is infected, do not scrap it easily. You can bury the infected bag in a soil with poor air permeability of 30 to 40 cm. After 10 to 20 days of anoxic treatment, you can effectively reduce the risk of miscellaneous bacteria, and you can still harvest mushrooms. . Pharmaceutical control methods refer to Trichoderma.

3. Mucor also known as black mold, long hair mold, hyphae initially white, pale gray to black later, in a high temperature, high humidity, poor ventilation under high incidence of conditions. When Mucor was infested during the cultivation of the mycelia of Lentinus edodes, the spoilage was rapid and spread over the substrate within a few days. The main reason for this is the use of moldy raw materials in the substrate. The inoculation environment contains many spores of mucormycetes, and mycelial culture is performed in a boring wet environment. The control method is the same as that of Trichoderma.
