Control of mites in edible fungi
1. Harm to the situation. Mites often bite the hyphae around the clumps, so that the injured hyphae can not germinate. Mites seriously damage the roots and hyphae of Auricularia auricula and Tremella fuciformis, affect the ear, and cause rotten and malformed ears.
two。 Prevention and control measures. Mushroom breeding rooms and mushroom houses should be far away from warehouses, feed rooms and chicken sheds. To often check bacteria, such as mites, cotton plug dipped in 50% dichlorvos fumigation, can kill mites and have no effect on mushroom hyphae. One week after sowing in the mushroom room, put a piece of plastic sheet on the material surface and pick it up for observation after 1-2 minutes. If mites are found, they must be completely eliminated before covering the soil. Generally, 0.5% dichlorvos was sprayed in the mushroom room, and under the greenhouse condition of less than 20 ℃, the doors and windows were closed, and the mushroom room with a cultivated area of 111m2 was fumigated with 1000 grams of dichlorvos for about 18 hours. If there are still a small amount of mites, spray 0.5% dichlorvos again. Mites harmful to Auricularia auricula can be sprayed with 0.5% dichlorvos, and mites on ear roots are sprayed with 1 ∶ 1000 times triclofenac.

A New method of sterilization of Edible Fungi
To clean the residue inside an old gasoline barrel, first build a stove with brick that is 10 centimeters higher and 10 centimeters wider than the diameter of the barrel, use 10 steel bars that are 16 millimeters thick and 30 centimeters long as stove bars, and leave the air duct of the blower on one side. Weld a steel pipe near the lid of the bucket wall and install a valve to add water and discharge pollution; on the other side of the bucket wall, weld 2 separate pipes (connected with black rubber pipe) to exhaust steam; weld a 4 cm long thin steel pipe l-shaped on each side of the lid, and a transparent plastic pipe is used as a water level gauge in the middle.

Prevention and Control of pollution in continuous cultivation of Edible Fungi
In the production of edible fungi, due to continuous cultivation, there are more and more miscellaneous bacteria, resulting in a sharp decline in the success rate of bacteria, and the mushroom stage is also easy to be infected with diseases. Those who are light will reduce production, while those who are heavy will fail. So, in the continuous cultivation and production of edible fungi, how to prevent pollution? In the production of edible fungi, the miscellaneous bacteria have certain specificity. Pleurotus ostreatus mixed bacteria do not affect Lentinus edodes, Lentinus edodes mixed bacteria do not affect Auricularia auricula and so on, even between different varieties of the same type is not easy to cross-infection. Therefore, attention should be paid to the replacement of varieties.
