What are the methods for controlling pests and diseases of silver ear fungus?
Silver ear fungus, also known as white wood ear, snow ear, or silver ear, has a smooth texture and a sweet, mellow taste. It has extremely high nutritional value and health benefits, and also has several beauty benefits, making it deeply loved by many people. However, during cultivation, silver ear fungus is more susceptible to pests and diseases than other mushroom species, so pest and disease control must be strengthened during cultivation. Let's take a look at the common pests and diseases of silver ear fungus below.
1. White rot
This disease mainly invades through the inoculation opening when the silver ear fungus mycelium matures, forming tumor-like protrusions. In the early stage, the mycelium becomes powdery white, and in the later stage it turns grayish-white. After being affected, the culture medium turns black. It mainly damages the base of the fruiting body, causing the base to rot and preventing normal fruiting. It also damages the ear pieces, producing a layer of white powdery spores on them, turning them into stiff ears.
Control methods: Increase ventilation, reduce humidity. If it occurs during the young ear stage, spray lime-sulfur mixture, and harvest early. Scrape it off with a knife down to the root, and apply a low-concentration carbolic acid solution to the base.
2. Green mold disease
This disease often occurs on the culture medium and fruiting bodies. When it develops, the mycelium is white, gradually turning light green and then dark green, and the contaminated culture medium also turns black, becomes foul-smelling and soft, until it is ruined. After the fruiting body is affected, it gradually discolors and rots, losing its commercial value. It is highly contagious, and if not controlled in time, it will spread on a large scale.
Control methods: The culture medium must be sun-dried and sterilized under high pressure before being used for cultivation. Aseptic operation must be carried out during inoculation. The temperature of the mycelium cultivation room should be 25-28 degrees, and should not exceed 30 degrees. After the disease occurs, it should be removed in time and sprayed with medication for control.
3. Mites
Mites, also called fungus lice, have many species. The common ones are Pyemotes mites and flour mites. Pyemotes mites are extremely small and invisible to the naked eye, usually gathering in groups and appearing grayish-brown; flour mites are larger, white and shiny, not forming clumps, and are numerous and powdery. They feed on mycelium, causing the mycelium to fail to germinate normally. During the fruiting stage, they often cause rotten ears or deformed ears.
Control methods: Ensure the mushroom house is clean and hygienic. Before the fungus bags are brought into the house, thoroughly disinfect and sterilize the mushroom house. When mite damage occurs, broad-spectrum low-toxicity pesticides such as fenpropathrin can be sprayed, but during the growth of fruiting bodies, spraying any pesticide is prohibited to avoid harming consumers.
