Mushroom Virus Disease - Biology and Epidemiology

Viruses are essentially non-living particles that need to exist inside a host to be able to survive and multiply. Two virus diseases of Agaricus bisporus are known:

  • La France disease, first recorded in 1948 in the United States.

  • Mushroom Virus X (MVX) disease, first recorded in the United Kingdom in 1996.

If virus disease is not identified early and management strategies implemented, virus infected mushroom spores will accumulate on farm, creating disease reservoirs.
