1, eliminate the source of insects. The harmful pests of fungus are Longhorn princes, termites, and moths. It is often overwintered in warehouse gaps, debris, and packaging materials. Therefore, before storage of fungus, indoor debris and outdoor weeds should be removed, and 80% of dichlorvos EC should be used to disinfect the empty bins. Generally 0.20-0.30 grams per square meter, with gauze strips dip liquid hanging in the room, sealed 2-3 days, and then ventilated for 1 day, you can ear into the warehouse. Finally, lime powder and malathion are applied around the warehouse to prevent outdoor pests from entering the house. 2, to prevent moisture. When the edible fungus is damp, it can easily cause pests. Therefore, before entering the warehouse, it must be dried so that the water content of the fungus does not exceed 12%, and it is air-dried into a plastic bag or aluminum can. After sealing, it is placed in a wooden box or carton lined with moisture-proof paper. Desiccant such as dry wood chips, quicklime and other moisture, check once every 10-15 days, if the desiccant has absorbed moisture, it should be removed after drying or drying into the box, if the fungus resurgence, should be promptly re-drying. 3, timely killing insects. If pests are found during storage, measures should be taken to eliminate them in time. First, the fungus was exposed to strong light for 1 day or with a dryer at 50°C for about 40 minutes to kill pests; second, the sealed warehouse lasted more than 20 days to kill all pests; and 3 was to take oxygen out of the warehouse. Inflow of nitrogen, or the infusion of carbon dioxide gas into the room to reduce indoor oxygen content to 2% or less, after two days, the insects died of suffocation, this method can prevent diseases up to 100%. 4, closed fumigation. When a large number of pests occur during the storage period of fungus, fumigants should be used to fumigate the warehouse. This method has obvious effects in the short term, and the commonly used fumigant is aluminum phosphide. Generally 6-9 grams per cubic meter of space, scattered in the warehouse, closed at 12 °C above 96 hours, after the end of the fumigation after the ventilation of air can be more than 10 days.
