Daughtrey A1 Craig R. Hibben A1 George W. Hudler YR 1988 UL http://auf.isa-arbor.com/content/14/6/159.abstract AB Native flowering dogwood (Cornus florida) in parts of northeastern United States have shown increasing dieback and mortality since the late 1970’s. Symptoms consist of necrotic spots, scorch, and blight of the leaves, nondehiscence of some blighted leaves, cankers, epicormic branches, and dieback beginning in the lower branches. The anthracnose fungus Discula sp. was identified as the primary cause. Post-infection stresses may have intensified tree decline. The fungicides chlorothalonil (Daconil 2787) or man-cozeb (Manzate 200) applied at 10-day intervals during leaf expansion reduced foliar symptoms. Additional recommendations are pruning, fertilization, and watering to promote tree vigor.
