Control methods of common diseases of Coprinus comatus

Coprinus comatus scientific name Maotou ghost umbrella, because its shape is like chicken leg, meat like shredded chicken, get the name chicken leg mushroom, its nutrition is rich, delicious, high nutritional value. Coprinus comatus has strong adaptability, maintain economic benefits in the addition period, and absorb a lot of cultivation, but in cultivation, disease is the main factor endangering the production of Coprinus comatus. Let's take a look at the prevention and control of common diseases of Coprinus comatus with Xiaobian.

1. Chicken claw fungus

Xanthomonas aeruginosa is a kind of parasitic pathogenic fungus when the harm is serious. It mainly occurs in the fruiting body formation and growth period of Coprinus comatus, which is named because its fruiting body is similar to chicken feet. During the mycelium growth of Coprinus comatus, it was disturbed by the pathogenic hyphae in the soil, and the two grew together to grow Coprinus comatus. When it occurs, the chicken claw fungus is dark brown and connected to the base of Coprinus comatus. The mycelium and Coprinus comatus will grab nutrients and transplant Coprinus comatus to grow, resulting in a serious reduction in yield or even no harvest, which generally occurs in a dark, humid and poorly ventilated environment.

Control methods: select high-quality bacteria, the culture material must be dry, fresh, no mildew, can be added to the culture material of low concentration carbendazim solution, can inhibit the growth of miscellaneous bacteria. Once the chicken claw bacteria are found, they should be dug up in time to prevent the bacteria from spreading, and do a good job of drug treatment at the infected place.

2. Rot disease

Rot is a common bacterial disease that mainly harms the fruiting body. At the initial stage of the fruiting body formation, the fruiting body turns brown, and then the fungal cap turns black and rotten, leaving only the stalk. It is easy to cause the disease in the environment of high temperature, high humidity and poor ventilation, and it is also easy to be infected by out-of-season cultivation in summer.

Prevention and control methods: before cultivation, the mushroom shed should be thoroughly sterilized with lime water, bleach or Jinxing disinfectant, and the air humidity and soil water content should be controlled well. Agricultural streptomycin can be used to prevent and cure the disease, and the diseased mushrooms should be pulled out in time to avoid infecting other mushrooms.

3. Brown spot

Brown spot mainly harms the surface tissue of the fruiting body and does not go deep into the fungal meat. brown spots appear on the cap or stalk of the fruiting body when the disease occurs. With the development of the disease, the whole fruiting body becomes brown, and there is mucus on the mushroom surface in a wet environment. The disease is easy to be induced by spraying contaminated water in high humid environment or during the formation of fruiting body, and it is also easy to be induced by out-of-season cultivation in summer.

Prevention and control methods: the water content of the covered soil should be controlled during mushroom production, and it is appropriate for the soil not to stick to the hand and the surface soil to show whiteness. When the air humidity is high, it is necessary to strengthen ventilation and reduce humidity, and avoid spraying water on the fruiting body during mushroom production. After discovering the diseased mushroom, remove it in time, and take it out of the mushroom room for pollution-free treatment and spray chemical control.

The above common disease control methods of Coprinus comatus are introduced. I hope it can help you. If you want to know more about it, please follow us.
