anthracnosePlant disease of warm humid areas, caused by a fungus (usually Colletotrichum or Gloeosporium). It infects various plants, from trees to grasses. Symptoms include sunken spots of various colours in leaves, stems, fruits, or flowers, often leading to wilting and dying of tissues. Dogwood anthracnose, caused by the fungus Discula destructiva, thrives in cool climates; in the U.S. it has caused severe losses to natural stands of dogwoods in mountainous regions. It is controlled by destroying diseased tree tissue, using disease-free seed and disease-resistant varieties, applying fungicides, and controlling insects and mites that spread anthracnose fungi from plant to plant. |

Iowa State Soybean Extension agronomist Palle Pedersen was one of many who sounded a renewed alert on commonly occurring fungal diseases, such as pythium, phytophthora, anthracnose and brown stem rot. For instance, Dirr describes the American plane tree as "truly at its 'best' when anthracnose [keeps] it devoid of leaves," while the original Camperdowni cultivar of Scotch Elm, in Dundee, turns out to be "rather pathetic and snaggle-toothed. Anthracnose, the deadly fungus that has killed wild dogwoods, has affected 70 percent of Mammoth Cave National Park in south-central Kentucky, according to the Associated Press. |
