Field Evidence Confirms Cornus kousa Dogwood’s Resistance to Anthracnose

Abstract

In a moisture regime very favorable for leaf disease infections (an overhead irrigation system), Cornus Kousa trees were infected by the anthracnose fungus (Discula sp.) and some died. In an adjacent comparable area, but with no overhead irrigation, C. florida trees were infected and dying but trees of C. kousa that touched them remained healthy…as is usual with that species.
