Systematics of Phyllocnistis leaf-mining moths (Lepidoptera, Gracillariidae feeding on dogwood ( Cornus spp. In the East, infections have been reported on flowering dogwood in Massachusetts, Connecticut, New York, New Jersey, Pennsylvania, and Delaware.

HOW to Identify and Control Dogwood Anthracnoseĭogwood anthracnose is a disease of flowering and Pacific dogwood ( Cornus florida and C. Cuticular erosion due to acid rain has the potential to predispose dogwoods in the eastern United States to anthracnose caused by Discula destructiva sp.nov. Cuticular cracking, desiccation, and erosion of trichrome surfaces were observed with decreasing pH for all samples. Samples were cut from the leaf tip, margin, and midvein of rain-treated trees and prepared for scanning electron microscopy.
Simulated rains were composed of a mixture of salts typical of ambient rainfall in the eastern United States and pH was adjusted to 5.5, 4.5, 3.5, and 2.5 with sulfuric and nitric acids. One-year-old, nursery-grown flowering dogwood seedlings were exposed to 1 cm of simulated rain 10 times over a 42-day period in 1990. of Agriculture, Asheville, NC (United States))Īcidic rainfall has the potential to influence anthracnose incidence and severity in flowering dogwood ( Cornus florida L.) of the eastern United States.

Influence of simulated acid rain on the flowering dogwood ( Cornus florida) leaf surfaceĮnergy Technology Data Exchange (ETDEWEB)īrown, D.A. The project was prompted in 2001 by the apparent abundance of flowering dogwoods along roadsides in the Morgantown, WV, area, despite a. The purpose of this evaluation monitoring project was to document the losses of flowering dogwood, Cornus florida (L.), an important ornamental and wildlife tree that grows across much of Eastern North America. Tracking population loss in Cornus florida since discovery of Discula destructiva, causal agent of dogwood anthracnose, in eastern North America
