How to prevent and control pests and diseases of white jelly fungus? Introduction to the latest methods
White jelly fungus, also known as white wood ear, snow ear, and white jelly fungus fruit body, has a smooth and moist texture, is sweet and mellow, and has extremely high nutritional value and health benefits. In addition, it has several beauty effects, and is deeply loved by many people. However, during cultivation, white jelly 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 white jelly fungus below.
1. White rot
This disease mainly invades from the inoculation opening when the white jelly fungus mycelium matures, forming a tumor-like protrusion. In the early stage, it causes the mycelium to become powdery white, and in the later stage it appears grayish white. After being affected, the culture medium turns black. It mainly harms the base of the primordium, causing the base to rot and preventing normal fruiting body formation. It also harms the ear pieces, producing a layer of white powdery spores on them, turning them into stiff ears.
Prevention and control methods: strengthen ventilation, reduce humidity, and when it occurs during the young ear stage, spray lime-sulfur mixture, harvest early, scrape it off together with the roots using a knife, 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 occurs, the mycelium is white, gradually turning light green and dark green, and the contaminated culture medium also turns black, smells foul, and becomes soft, until it is discarded. After the fruiting body is affected, it gradually discolors and rots, losing its commercial value. It is also highly contagious, and if not controlled in time, it will spread on a large scale.
Prevention and control methods: the culture substrate must be exposed to the sun and treated with high-pressure sterilization before being used for cultivation. Aseptic operation must be carried out during inoculation. The temperature of the spawn-running cultivation room should be 25-28 degrees, and should not exceed 30 degrees. After disease occurs, it should be removed in time and sprayed with pesticides for control.
3. Mites
Mites are also called fungus lice. There are many types, and the common ones are Pyemotes mites and flour mites. Pyemotes mites are extremely small and invisible to the naked eye, generally gathering in groups and appearing grayish brown; flour mites are larger, white and shiny, do not form clusters, are numerous, and appear 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.
Prevention and control methods: ensure the mushroom house is clean and hygienic. Before the fungus bags enter the house, the mushroom house must be thoroughly disinfected and sterilized. When mite damage occurs, broad-spectrum low-toxicity pesticides such as fenpropathrin can be sprayed, but during the growth of the fruiting bodies, spraying any pesticide is prohibited to avoid harming consumers.
