Minor Pest Title
Die-back disease (Virus)
Minor Pest Description
It causes spots in the casing soil where no mycelial growth occurs. Around these spots, mushrooms of low quality appear with long stems and dirty caps. Sometimes the only indication of a virus infection is low yield. In severe cases, a few deformed mushrooms are produced. The disease can be introduced to the farm by infected spawn. It is spread by spores and mycelium from infected mushrooms. Mushrooms affected with the virus open fast, releasing infected spores. Sometimes, mushrooms that were formed inside the casing layer come out already open. Spores from infected mushrooms are easily carried by wind, insets, on implement, clothes and hands of personnel.
