Abstract

Coffea arabica L. has commercially grown in more than 10.5 million ha in 80 different countries worldwide. Ethiopia is the largest Arabica coffee producer in Africa and 5th one from the world. Coffee is vital to the economy of East and Central Africa, providing a major source of foreign exchange earnings and as a cash crop, supporting the livelihood of millions of people who are involved in cultivation, processing, marketing, and export. However, coffee production in Ethiopia is highly restricted by diseases such as the Coffee leaf rust (CLR) whose causal agent is the fungus Hemileia vastatrix. This study was done to assess the prevalence, incidence, and severity of coffee leaf rust in coffee-growing areas of East Wallaggaa Zone of Oromia. During survey work, 3 potential coffee-growing districts (Diggaa, Sibu Sire, and Gudeya Bila) were used. Accordingly, 3 PAs per district, and 5 coffee farms per PA were used. Totally, 45 coffee farms were used for this survey work. Data was collected on the prevalence, incidence, severity, and impact of some factors on the development of CLR. CLR was observed across the surveyed area with a value of 100%. High CLR incidence was recorded in Gudeya Bila (98.67%) followed by Digga (77.33%) and Sibu Sire (77.33%). While the highest severity was recorded in Diggaa (39.18%) followed by Sibu Sire(36.67%) and Gudeya Bila (34.99%). CLR has influence positively and nega-tively by altitude, shade tree status, host resistant, coffee age and sanitation and field management. Local farmers should use CLR-resistant coffee cultivars and recommended field management to overcome CLR pressure observed in the coffee industry. Further investigation is also needed on the influence of some factors on the development of CLR in the study area.
