What if Pleurotus ostreatus grows green mold?
Recently, Xiajin County, Shandong Province, Nancheng Town, Zhu Miao Village Pleurotus ostreatus cultivation household Li Zhibao telephone consultation: This year Pleurotus ostreatus market is good, wholesale price 1.5 yuan/catty, he suddenly invested 20000 jin material cultivation Pleurotus ostreatus, but now Pleurotus ostreatus cultivation bag grows some green things, experienced people say it is green mold, do not know what to do? The author replied as follows:
Chloromycete is the main disease in edible fungi cultivation. It mainly occurs on the fungus mass without fungus or on the culture medium without thorough disinfection. Chloromycete is easy to breed in acidic and humid environment. Its spores spread quickly in the air and reproduce rapidly. If it is not handled in time, it will suffer heavy losses.
Control measures: reduce the temperature and humidity of mushroom room, increase ventilation, and cover mold with plant ash to prevent mold spores from flying and spreading. First use 3% lysol solution or 3% formaldehyde solution indoor spray fumigation, and then use 1% potassium permanganate solution to clean mold. After sprinkling potassium permanganate particles on the mold, spray water on the periphery of the mold. 9 parts of quicklime and 1 part of carbendazim are mixed with proper amount of water to wash the mould. Soak mold in 5% lime water, remove lime water after mold disappears, and add new material. Inject green mold in the bag or wash the green mold on the bed surface with 1:200 Clomid solution. Spray the mold part of the bag with 1:800 benomyl solution. Brush the mold with 95% alcohol or kerosene, burn it, then dig it out and fill it with new material. Spray mold with 3% Lysol solution, clean tools and dig mold out, clean tools once every time, fill culture and bacteria after digging. This method can completely eradicate late mold. In uncooked culture, adding 100g Clomid per 100kg of culture medium can completely eradicate mold breeding.

Prevention and treatment of common diseases of Pleurotus ostreatus
In cloudy days, lack of light and high relative humidity in the mushroom shed, Pleurotus ostreatus is extremely prone to two complications: soft rot and bacterial spot disease. So how can we prevent and cure this complication? according to our practical experience, we specially introduce the following comprehensive prevention and control methods to mushroom farmers. 1. Breeding disease-resistant varieties and cultivating strong hyphae to improve the disease resistance of Pleurotus ostreatus. Such as: Hebei without spores, Jiangsu wild wind, etc., the mycelium growth is snow-white, the fruiting body has strong disease resistance and high yield. 2. Increase ventilation and purify the air environment. 3. Use sewers to replenish water

The reason for the poor growth of Pleurotus ostreatus
Some Pleurotus ostreatus growers write to say that their Pleurotus ostreatus is not growing well and want to know what the problem is. Here are some analysis and reminders on some problems often seen in cultivation: the first reason may be that the ambient temperature and material temperature are not right. If the temperature range of mushroom production is higher or lower than that of the cultivated varieties, there will be no mushroom emergence or the phenomenon that the mushroom will no longer produce normally after a tide of mushroom turning to tide. The second reason is the poor ventilation of the mushroom shed. Poor oxygen supply and high carbon dioxide concentration are not conducive to mushroom production, and will increase when severe hypoxia occurs.
