Citation: Degete AG (2021). First report of the smut pathogen on tef (Eragrostis tef) in Ethiopia. J. Agri. Res. Adv., 03 (03):23-25
Aim: The survey aimed to collect unusual tef disease
samples observed in the field and report the newly recorded disease.
Materials and Methods: The samples from diseased tef varieties were
collected and observed under a microscope directly without culturing because
the pathogen is obligate.
Results: The smut spore cells with slightly circular shapes
were observed and identified. The smut species of tef can attack the organ of
the tef productive part before heading of the crop. On the infected part of the
tef swelled filled with teliospores were observed. The disease was observed on
Quncho, Magna, and Boset at Southern Nation nationality of People around Alaba
zone and West Arsi Zone around Negelle Arsi and Shashemene (Oromia) in Ethiopia.
The diagnosis was easily confirmed by planting imbibed and un imbibed Quncho
variety in the greenhouse. On the imbibed tef with teliospores of smut gives
some symptoms observed in the field and nothing observed in the unimbibed tef
variety Quncho.
Conclusion: It was concluded that species-level
identification of this pathogen, evaluation of tef genotypes against this
disease and host range identification may future work of the pathogen.
