Book excerpt: Excerpt from Pitch Canker of Southern Pines: Identification and Management Considerations Pitch canker1 is a major disease of planted pines in the South. Crown die back, stem deformity, reduced growth rate and mortality are most severe on slash pines, but Virginia, shortleaf, loblolly, longleaf, south Florida slash, pitch, Table Mountain, sand and eastern white pines are also susceptible. Before 1974 and the start of the present epidemic in northeastern Florida, the disease oc curred sporadically and caused variable amounts of damage. By 1976, the disease was present on an estimated million acres ha). In several, severely affected, east - central Florida counties, more than 51 percent of the planted slash pines were infected. The disease has recently intensified in western Florida and is frequently found in southeastern Georgia and on planted slash pine in South Carolina. Elsewhere in the South, damage has most often been restricted to seed orchards of slash, longleaf, Virginia, shortleaf and loblolly pine. Cone produc tion has been dramatically reduced in severely diseased orchards. The disease is most severe in orchards where the trees have been wounded by natural means or by cultural practices. Some clones in seed orchards are severely affected while others in the same orchard remain disease - free.
