![]() It affects mostly young vegetation, and is not harbored in soil.įungicides containing tebuconazole have proven effective against this disease. This is a systemic disease that invades foliar tissue and germinates there. Where there should be pollen-laden anthers, there are sooty spores instead. It retards growth, makes the foliage grassy-looking, and damages flower buds and blooms. This type affects members of the carnation family. There has been and will continue to be much reclassification with scientific advancement in this area. It is now known as Microbotryum violaceum, and has been reassigned to the Microbotryaceae family, which also contains fungi. AntherĪnther smut fungus was formerly classified as Ustilago violacea, in the Ustilaginaceae family, and considered a “true” smut. This type is systemic, and can winter over in the anemone rhizome, or fleshy root, and cause infection again the following year. Photo by Jerzy Opioła, Wikimedia Commons, via CC BY-SA. Spores can overwinter in soil, plant debris, rootstock, or seeds, just waiting to germinate.Įxamples of smuts and the species-specific fungi that cause them include, but are not limited to: AnemoneĪnemone smut, Urocystis anemones, appears as yellow/brown blisters on the foliage and stems that darken to brown/black, and release masses of sooty spores.Īnemone smut, Urocystis anemones. ![]() ![]() When the spores are dispersed, they may be carried by a breeze, an insect, or water to species-specific host plants. The fungi cause dark streaks and blisters on plants that develop into galls that contain masses of spores. Some fruits may be unaffected, and seed and debris may not carry the disease. Localized damage, on the other hand, affects specific portions of plants. When an infection is systemic, entire plants are affected, and their seed and debris can further spread disease. Others are localized, damaging only the parts they come in direct contact with. Some varieties inflict systemic damage, living in plant tissue and evolving as a plant grows. Rather, there are many host-specific species. ![]() There isn’t just one type of black smut fungus. Let’s learn about this challenging disease. ![]()
