Wheat Leaf Rust (Puccinia triticina) Epidemics and Host Plant Response in South Tigray, Ethiopia

Teklay Abebe Teferi

Leaf (brown) rust has been an important wheat disease in Ethiopia. Periodic epidemics are ongoing with grain losses up to 75%. Surveys were conducted in the Tigray area from 2010-2013 to monitor the spatial and temporal dynamics of the leaf rust pathogen population and host response. It was based on inspection of wheat fields randomly selected at 5-10 km intervals along accessible routes. Total 66, 52, 61 and 70 fields were examined in 2010-2013 with prevalence level of 35, 12, 20 and 17%, respectively. The disease incidence and severity reached 100% on Raya-Azebo and Raya-Alamata districts at many locations. The overall mean incidences and severities from 2010-2013 were 24 and 18%, 5 and 20%, 7 and 15% and 13 and 27%, respectively. Fifteen leaf rust differential hosts were found effective to the pathogen populations and could be used as potential sources for the development of resistant varieties.
