The pests that need to be controlled when cultivating white fungus are:
1. Fungus gnats Mainly small fungus gnats. Control measures: regularly clean up the environment and spread lime powder for disinfection; install screen mesh on doors and windows, and regularly spray pyrethrum liquid or 2000-fold dilution of Yitaibao on the mesh; install blacklight lamps inside the room to trap and kill them. During the peak occurrence period, restrict pesticide use to low-toxicity, low-residue varieties, such as spraying 3000-fold dilution of Regent to kill them, or burn mosquito coils, or crush sanitary pills and fumigate to kill them.
2. Mites Also called fungus lice, with many varieties, commonly including Tyrophagus putrescentiae and flour mites. Control methods: the raw material warehouse should be far away from the mushroom house, and materials should be sun-dried before use; the surrounding environment should be cleaned thoroughly; disinfect before opening the fungus bags, spraying 3000-fold dilution of 73% propargite 1 day in advance, then adjust the room temperature to 20°C, close doors and windows for thorough empty-room disinfection, and after the residual chemical odor is removed, open the adhesive tape; if mite damage occurs in the early stage of fruiting body growth, fresh tobacco leaves can be spread flat beside the fungus bags to attract mites to gather on the leaves, then remove and burn them to death; tea seed cake can also be ground into powder, stir-fried over low heat until it smells oily, then removed from the pan and sprinkled at the mite-damaged area, and after attracting them, remove and scald them to death with boiling water. If unavoidable, spray 1000-1500-fold dilution of 20% amitraz emulsifiable concentrate to kill them.
3. Nematodes Control methods: the culture medium must be thoroughly sterilized, the water source should be tested, the mushroom house should be strictly disinfected in advance, watering should not be too wet, and attention should be paid to ventilation. If nematodes appear in the mushroom house, use 0.5% lime water or 1% salt water, spray 2-3 times on cool days, and spread lime powder on the floor of the mushroom house for disinfection. During the long-ear stage, 1% glacial acetic acid or 25% rice vinegar solution can be sprinkled on the diseased spots.
