The following informative website may be helpful:http://pnwhandbooks.org/plantdisease/dogwood-cornus-spp-anthracnose

It describe the disease, offers suggestions for cultural controls, says when to spray, and recommends 2 sprays that are available to the home gardener (see H after the product name):

Bayer Advanced Disease Control at 0.75 fl oz/gal water. H

  • Bonide Fung-onil Multi-purpose Fungicide at 2.25 teaspoons/gal water. H
  • Meanwhile water the tree deeply, keeping water off the leaves, and continue to water well throughout the growing season.
