Green mold, also known as green Trichoderma, is one of the most serious pathogens that injure Pleurotus ostreatus. It suffers from various hazards in the different stages of production of Pleurotus ostreatus. Once the disease develops, lighter crops and severe crop failure are important for the development of Pleurotus ostreatus. obstacle. Through several years of exploration experiments, the comprehensive prevention and control measures are summarized as follows: (1) Doing a good job of disinfecting the mushroom house Thoroughly disinfects the mushroom house and its surrounding areas to eliminate all kinds of debris. Use lime or yellow mud to sew walls. Use 10% fresh lime water to brush the walls, roof and bed frame, use Suer to spray the ground, roof, and then sprinkle lime powder on the ground, and finally do not need 10ml/m3 formaldehyde plus 5g/m3 potassium permanganate Vaporization for fumigation. During the cultivation of Pleurotus ostreatus, regular application of 0.1% potassium permanganate or 3%-5% carbolic acid. (II) Selection of fine strains Pleurotus ostreatus strains should be selected as high-quality strains with dense, white, thick, strong anti-miscellaneous ability, no pollution and age. (C) The use of high quality culture materials should be fresh and non-polluting. The ingredients can be added with about 2% lime, 1% gypsum and a peaceful co-existence of 0.1%-0.2% carbendazim, which can inhibit the growth of green mold. If the culture material is not fresh or has mildew, it should be used after high temperature fermentation. (D) to strengthen the cultivation and management of mushroom house temperature in the early stage of cultivation should not be too high, the air humidity controlled at about 70%, unfavorable to the growth of mold in the air, but does not affect the growth of Pleurotus mycelium. When cultivated, the amount of seeds used can be increased, and the amount of general strains should account for 10%-15% of the dry weight, so that Pleurotus ostreatus mycelium can develop growth advantages in a short period of time. During the cultivation process, proper ventilation and ventilation, control mushroom house environmental conditions, so that it is conducive to mycelial growth, inhibition of green mold. (5) When a small amount of green mold occurs on the culture material of the bed or on both ends of the bacterial bag, 0.1% thiophanate-methyl, 0.1%-0.2% zeocin, 0.1%-0.2% carbendazim or concentrated lime water are used. Smearing or spraying of the affected parts with the clear liquid can prevent the spread of conidial spores, or treatment of infected parts with a mixture of 2% formaldehyde and 5% carbolic acid can inhibit the growth of various bacteria. If the bed of bacteria or bacteria in the bag has penetrated into the material, it should be timely covered with 0.2% carbendazim liquid soaked in sand, and then gently dig out the contaminated material, spray the material after the removal of 0.2 % Carbendazim or other fungicides can also be applied with thick lime milk and then filled with fresh material or strains to control its development. For deep contamination of bacteria bags can be buried deep processing. During the mushrooming period, 70% thiophanate-methyl, 50% carbendazim 1000-fold, or 10% water-strengthening agent can be sprayed once every 3-5 days. .
