Ament M, Augé RM, Grand L., Windham M. 1998. An inoculation technique for dogwood anthracnose. Journal of Environmental Horticulture 16:37-41. Researchers have been generally unable to infect dogwood foliage ( Cornus florida L.) with dogwood anthracnose ( Dicula destructiva Redlin) in artificial environments. We tested the influence of four factors on development of D. destructiva lesions in intact C. florida leaves as wounded with a pin-prick device: (1) propagule (conidia or vegetative hyphae), (2) isolate origin (Catoctin Mountain, Maryland or Great Smoky Mountains National Park, TN), (3) controlled environment (growth room or air conditioned, humidified chamber in a greenhouse) and (4) period of time leaves were enclosed in humidified bags following inoculation. Of the manipulated factors, time spent in moistened bags and experimental environment were most important in determining lesion size. Lesions of similar size resulted from 0, 2 and 4 days in humidified bags, but leaves enclosed for 7 days had lesions over 5 times as large. Lesions that formed on trees in the greenhouse chamber were about 8 times larger than those in the growth room. Neither fungal propagule nor isolate origin affected lesion size. Based on this information, we have successfully infected both C. florida and Cornus kousa with D. destructiva in subsequent studies.
