Pitch canker disease, caused by Fusarium moniliforme var. subglutinans, is reported for the first time in plantations of loblolly (Pinus taeda) and pond pine (P. serotina). In 1983, pitch canker caused a high incidence of dieback on plantations in eastern North Carolina. Loblolly pines with terminal dieback were smaller in both height and diameter than healthy trees, whereas only pond pines with severe terminal dieback were shorter but not smaller in diameter than healthy pond pines.
