The strain culture room should be regularly inspected and fumigated. When producing strains, cotton balls should be used to tighten the test tubes and a layer of kraft paper should be used to prevent insects from invading. If pests have been found, they must be treated by fumigation or low temperature freezing and the pests can be used only after checking to determine the death of pests.
After harvesting mushrooms, we must carefully clean the surface of the material, remove mushroom roots and ragweed mushrooms and concentrate deep. Fumigation (including racks, tools, etc. used for mushrooms) should be performed on old culture rooms with severe disease. The method is: fumigation with a ratio of 40 grams of potassium permanganate in 80 ml of formalin per cubic meter volume, the container containing potassium permanganate should be deep, and its volume should be larger than that of formalin. 40 times more. Close the cultivation room when fumigation, open the doors and windows after two days for ventilation, and then put the bag into the bag after 24 hours. Sulfur can also be used for fumigation, the amount of 5 grams per cubic meter, closed 48 hours after the ventilation and then feed.
After finishing collecting 3 to 4 oyster mushrooms, the granules shall be removed in time, and the high-temperature compost fermentation or spraying shall be performed away from the mashroom to prevent the insects from multiplying in the waste. It is forbidden to place a new mushroom house together with the old and new culture blocks to prevent pests from spreading to the new mushroom block. In addition to the fumigation and secondary fermentation of the culture material, the casing material also has to undergo high temperature or chemical treatment. To properly water, in particular, to avoid direct spray water to the mushroom body, excessive watering, mushroom bed and mushroom house humidity caused by the general assembly of mycelium and mushroom bud rot, easy to breed pests.
