Annually both Belg and main seasons survey of tef diseases was done. In each of the 2019 and 2020 the cropping season, survey of tef diseases was done in both short rainy and long rainy seasons. The survey aimed to monitor emerging or new tef disease in major tef growing regions. During the 2019/20 and 2020/21 cropping season survey, new disease was observed in different areas. The survey aimed to collect unusual tef disease samples observed in the field and report the newly recorded disease. The samples from diseased tef varieties were collected and observed under a microscope directly without culturing because the pathogen is obligate. This disease is known to attack the reproductive organ of the tef plant before heading. The infected part of the plant was swollen and was filled with teliospores. The disease was observed on Quncho, Magna, and Boset varieties in Alaba Zone and West Arsi Zone around Negelle Arsi and Shashemene in Southern Nation Nationality and People and Oromia region, respectively. The diagnosis was easily confirmed by planting imbibed and un imbibed seeds of Quncho in a greenhouse. Imbibed seeds with teliospores of smut gave the same signs to the one observed in the field, while signs were not observed in the unimbibed seeds. The spore cells were slightly circular shapes and measure 5-10 µm in diameter was observed. On the basis of these morphological features; the disease was identified as smut. Species-level identification of this pathogen, evaluation of tef genotypes against this disease, distribution of the pathogen and host range identification is future works.
