Title: Black Gum Mortality (Pest Alert)

Author: USDA Forest Service,;


Source: Misc. Publ. Newtown Square, PA:U.S. Dept. of Agriculture, Forest Service, Northern Area State & Private Forestry

Publication Series: Miscellaneous Publication (MISC)

Description: A large number of black gum trees (Nyssa Sylvatica) have been found dying in North Carolina, Tennessee, Virginia, and Georgia. The observed trees have been in the mountains of these States. The trees are often associated with dogwood trees infected with Disculd sp., which causes dogwood anthracnose. The symptoms on black gums include leaf spots, leaf blotches, leaves dying and hanging on the trees, branch cankers, shoot dieback, and tree death. The affected trees are usually in the shade. A number of fungi have been isolated from the trees, but the causal organism is unknown.

Keywords: Leaf spots, branch canker.
