Infection from the bracts then moves to the foliage. Young shoots and berries may develop elongated, scabby lesions that have distinct purple borders. The fungus persists from year to year in infected twigs, fruit, and other plant tissues. If the weather is dry before or during the flowering period, very little disease will be observed. Infections will vary from year to year because of this dependence on free moisture.
Spot anthracnose is much worse on flowering dogwoods growing in the full sun than in shade.
Planting new dogwoods, especially early flowering cultivars, on shaded sites often will prevent disease development. In most cases, fungicide sprays are not necessary, as the disease does not result in significant decline or death of dogwoods. If fungicides are used, apply them from bud swell through bloom. Sanitation may help if the infected tree is isolated. Slow to medium grower.
