Tremella, also known as white fungus, snow fungus, Tremella fuciformis, its taste is smooth, sweet and mellow, has a very high nutritional value and health care effect, in addition, there are several cosmetic effects, loved by many people. But in cultivation, Tremella is more likely to be infected with diseases and insect pests than other strains, so it is necessary to strengthen the prevention and control of diseases and insect pests during cultivation. Let's take a look at the common diseases and insect pests of Tremella fuciformis.

1. White rot

The disease is mainly caused by the invasion of the mycelium of Tremella fuciformis from the inoculation mouth to form a protruding substance of the tumor, which causes the hyphae to be white in the early stage and gray in the later stage, and the culture medium becomes black after the injury. The main harm to the original base, resulting in base rot, can not be normal out of the ear, but also harm the ear piece, produce a layer of white powder spores above, making it into a stiff ear.

Prevention and treatment methods: strengthen ventilation, reduce humidity, spray lime-sulfur mixture in the young ear stage, and harvest in advance, scrape off the roots with a knife, and smear a low concentration of lime acid solution on the base.

2. Green mold

The disease often occurs in the culture medium and fruiting body, when the disease occurs, the hyphae are white and gradually become light green and dark green, while the contaminated medium will also become black, smelly and soft, until it is scrapped. After the onset of the disease, the fruiting body will gradually change color and decay, lose commodity value, and it is highly contagious, not timely prevention and control, will spread on a large scale.

Prevention and treatment: the culture medium should be used for cultivation after exposure and high pressure sterilization, aseptic operation should be achieved during inoculation, the temperature of the culture room should be at 25-28 degrees, not more than 30 degrees, and the disease should be removed in time after the disease. and spray medicine to prevent and cure.

3. Mites

Mites are also called fungus lice, there are many kinds of mites, there are two kinds of common mite and acaroid mites, the volume of mite is very small, invisible to the naked eye, generally gathered together in groups, showing grayish brown, while the volume of acaroid mites is larger, white shiny and not agglomerated, the number is more, powdered. They feed on hyphae, causing hyphae not to germinate normally, and often cause rotten or malformed ears during the ear emergence period.

Prevention and control methods: to ensure the cleanliness and hygiene of the mushroom room, the mushroom room should be thoroughly disinfected and sterilized before entering the room. When mite damage occurs, it can be sprayed with broad-spectrum, low-toxic pesticides such as disinfectant, but during the growth of the fruiting body, it is forbidden to spray any pesticides so as not to harm consumers.
