Light intensity and drought stress as predisposition factors for dogwood anthracnose. Larger trees often die 2 to 3 years after the first symptoms are found in the leaves. Particularly in the eastern states, dogwoods have a strong emblematic value. Symptoms include dieback on the branches in the early summer with dried leaves on twigs. Anthracnose can be avoided by destroying diseased parts, using disease-free seed and disease-resistant varieties, applying fungicides, and controlling insects and mites that spread anthracnose fungi from plant to plant. Dogwood anthracnose is a disease caused by the fungus Discula destructiva. All in the cycle of life and death anthracnose life cycle Home; Blogs; anthracnose life cycle; 01 Any organism that spends part of its life cycle within the woody part of a plant, including either the outer bark, the inner bark, and/or the stem wood. Early in the growing season, fruiting structures erupt through the bark of infected twigs and on the underside of spotted leaves. The Life Cycle of Foliage Pathogens The life cycle of many Ascomycete foliage pathogens is remarkably similar (Fig-ure 13.3). Nearly all trees showed some symptoms (lower branch and twig die-back, conidiomata on leaves, leaf blotch). Spores produced in these fruiting bodies infect new growth as it emerges, particularly during moist weather. Discula quercina (West.)
