Impacts of dogwood anthracnose (Discula destructiva Redlin) on the fruits of flowering dogwood (Cornus florida L.): implications for wildlife. Chemical Control for Dogwood Anthracnose. Molecular phylogeny of dogwood anthracnose fungus (Discula destructiva) and the Diaporthales Ning Zhang1 Meredith Blackwell Department of Biological Sciences, 202 Life Sciences Building, Louisiana State University, Baton Rouge, Louisiana 70803 Abstract: Dogwood anthracnose, caused by Discula destructiva Redlin (1991), is a disease of several native Arx., the anamorph of Apiognomonia quercina (kleb.) • Brown spots on leaves, 0.25” in diameter, can be circular or irregular, visible on top and bottom of leaves, and have smoky, purple-brown margins. Discula destructiva. 92 (12), 1276-1283. Dogwood anthracnose (Discula destructive) is a damaging and destructive disease that affects various dogwood species. Detailed coverage of invasive species threatening livelihoods and the environment worldwide. Spores produced in these fruiting bodies infect new growth as it emerges, particularly during moist weather. Discula destructiva, foe of beauty. 1999; 83:806–809. Larger trees often die 2 to 3 years after the first symptoms are found in the leaves. Pitch canker life cycle. Lymantria dispar. Erythrina Gall Wasp.

The Life Cycle of Foliage Pathogens The life cycle of many Ascomycete foliage pathogens is remarkably similar (Fig-ure 13.3). Mycologia, 87(4):490-500. Arx., the anamorph of Apiognomonia quercina (kleb.) Dogwood anthracnose: understanding a disease new to North America. The individual life cycle of the periodical cicada is long but relatively simple. A new distribution map is provided for Discula destructiva Redlin Fungi: Ascomycota: Diaporthales Hosts: Dogwoods, Cornus florida, C. nuttallii and other Cornus species. This life strategy was confirmed by Anselmi et al. (Dogwood Anthracnose. A few fungi produce ascospores in late summer and early fall and the fungi involved infect buds. Disease generally appears from May to July, but moist weather can promote further infection any time during the Plant Disease, 78(4):398-402, Britton KO; Roncadori RW; Hendrix FF, 1993. Dogwood anthracnose. When several references are cited, they may give conflicting information on the status.

Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Plant Disease. Redlin S C, 1991. It causes dieback or even death of infected trees. Dogwood anthracnose is a disease caused by the fungus Discula destructiva. Flowering dogwoods (C. florida) have had some difficulty with the anthracnose fungus Discula destructiva, also called dogwood blight, which can kill part or, rarely, all of the tree. • More severe impact on young and/or understory dogwoods, • Flower bracts develop smoky, purple-brown margins Histological investigation of infection processes of Discula destructiva on leaves of Cornus florida. Quadrastichus erythrinae. Life Cycle. Erbaugh DK; Windham MT; Stodola AJW; Auge RM, 1995. LIFE CYCLE.
