Abstract
JONES, C., G. J. GRIFFIN, and J. R. ELKINS. 1980. Association of climatic stress with blight on Chinese chestnut in the eastern United States. Plant Disease 64:1001-1004. In commercial and home plantings of Chinese chestnut in Georgia, North Carolina, Tennessee, Virginia, West Virginia, and New York, 23% of the trees had main stem cankers incited by the chestnut blight fungus, Endothiaparasitica. The average main stem canker size was 28 X 55 cm. Fifteen percent of the trees had infection over 50% or more of the limb circumferences. Only two blighted trees were killed. In general, main stem canker incidence (13-93%) was higher in plantings of the Appalachian Mountain region than in plantings of the Piedmont region (2-13% incidence). Trees that were damaged most by E. parasitica cankers were located in high-wind and cold-winter areas of the Appalachian Mountains.
