Pitch canker in seed orchards (1981)Dwinell, L., & Barrows-Broaddus, J. (1981). Pitch canker in seed orchards. Paper presented at the Proceedings of the Sixteenth Southern Forest Tree Improvement Conference- 1981. Retrieved at https://rngr.net/publications/tree-improvement-proceedings/sftic/1981/pitch-canker-in-seed-orchards Pitch canker, caused by Fusarium moniliforme var. subglutinans, is a serious disease of pines in southern seed orchards. The disease has been confirmed in over 30 seed orchards from North Carolina to east Texas on a wide range of economically important pine s p ecies. Symptoms include branch and bole cankers, and shoot dieback. Wounds are readily infected by the pitch canker fungus. Within pine species, individual clones vary markedly in their susceptibility to infection and incidence of disease is frequently related to the geographic source of seed. This fungus also causes conelet abortion, mortality of maturing cones, and seed deterioration. Control strategies and current research initiatives are presented https://rngr.net/publications/tree-improvement-proceedings/sftic/1981/pitch-canker-in-seed-orchards
