Contributed by Dr. Scott A. Enebak School of Forestry & Wildlife Sciences, Auburn University 108 M. White Smith Hall, Auburn Alabama 36849
Host: Spruce pine (Pinus glabra Walt.) Disease name: Pitch CankerPathogen name: Fusarium circinatum (Nirenberg et O'Donnell, sp nov.) = Fusarium subglutinans f. sp. piniPitch canker was first described in the United States on Virginia pine in 1946 and is now believed to have entered the country from the central Mexico where the fungus may have co-evolved with Pinus spp. While spruce pine is seldom abundant, the tree is found scattered among hardwoods along riparian zones through the southern gulf states into South Carolina. In the southern United States the disease has been dramatic on slash (P. elliottii), loblolly (P. taeda) and longleaf pine (P. palustris). Recently, the fungus and consequently the disease, has been reported in California, South Africa and Chile infecting Monterey pine (P. radiata). In addition to these species, Fusarium circinatum has been found on 21 other pine species.
