Biology, diagnosis and management of Heterobasidion Root Disease of southern pines

Informally Refereed

Abstract

Heterobasidion root disease (previously called annosum, annosus, or Fomes root disease / root rot) is one of the most economically damaging forest diseases in the Northern Hemisphere. Heterobasidion root disease (HRD) in the southeastern U.S. is caused by the pathogen Heterobasidion irregulare, which infects loblolly, longleaf, pitch, shortleaf, slash, Virginia, and white pine; eastern red cedar; and incense cedar. This disease is predominately found in pine plantations after thinning on sites with well-drained sandy soils.
