Field surveys were conducted in 2016 and 2017 belg season to generate baseline information on the type of pests prevailing in Belg and irrigated tef. The survey was conducted in five zones. Weeds were sampled in four 50 cm x 50 cm quadrats and the number of individual weed plants were counted and identified to species level in situ. Insect pests and diseases were determined by visual search for damages done by insects or symptoms of diseases throughout the field. Tef shoot flies (Atherigona spp.), maize aphid (Rhopalosiphum padi) and unidentified stalk borer infested tef. But the severity of damage caused by these insect pests was trace to 10%. Tef rust (Uromyces eragrostidis) and Sclerotium sp. were prevalent in limited tef fields. Tef is also attacked by different bird species. More than 22 weed species in more than 14 families were recorded throughout the surveyed areas. The two families Poaceae and Compositae accounted for the larger proportion of weed species. In the 2016 season Cyperus spp., Portulaca oleracea, Parthenium hysterophorus, Amaranthus hybridus and Xanthium strumarium, in decreasing order, were the most abundant weed species, whereas in the 2017 season Setaria pumila, Eragrostis cilianensis, P. hysterophorus and Argemone ochroleuca, in decreasing order, were abundant weed species. Field bindweed, Convolvulus arvensis, which is found only in East, Southwest, and West Shewa Zones, was found in one field sown to Quncho.
