Recently, Fu Shenggao, who lived in the dry dam village of Taian Township, Dongxing District, told reporters that he had purchased a batch of shiitake mushrooms from the field (when the mushrooms had been bought and matured), they were shipped home for a few days and the shiitake mushroom was The growth is normal. Seeing that mushroom grows quickly, mushrooms have shrunk quickly and some green and white molds grow. Did not pay attention to the beginning, who expect the more the longer the mold, has now grown a large area of ​​moldy. He wants to know if there are any remedies. According to Lai Shuqun, Director of the Dongxing District Bureau of Agriculture, the green spot on the shiitake mushroom should be green mold. The green mold produced by the bag mushroom is likely to be caused by high ambient temperature, high humidity, and poor ventilation. In addition, during the transportation of the bacteria bags, the spores of Pyrococcus can easily enter the bacteria bag due to frequent vibrations. In addition, the hyphae are harmed, the resistance is weakened, and they are easily contaminated. Director Lai suggested that the sterilizing of culture materials should be thorough, or 0.5% carbendazim should be added when preparing the culture materials to inhibit their growth. During the process of mycelial culture, it was found that the heavily infected bacteria bags (bottles) need to be picked out and away from the fungus mushrooming site. If it is not a serious patch-like dissemination, the bag can still be used, but it is best to manage it separately from the quality bag. When the mushroom is unbagged and when the first and second tidal mushroom come out of fruiting period, the green mold can be smeared with 0.2% carbendazim or 0.2% zeocin, or concentrated lime water (5%) to prevent the spread. Treatment of the infected sites with a mixture of 2% formaldehyde and 5% carbonic acid also inhibits their growth. In the middle and late stages of fruiting, green molds appear, and the sun canopy can inhibit the growth of mushrooms. However, if the area polluted by the green mold is too large, it cannot be remedied.
