Abstract

Production and productivity of maize, sorghum, Haricot bean Mung bean cow pea and coffee are highly threatened by different diseases in South omo and Segen peoples zone of Southern Nation Nationality Peoples Region of Ethiopia. However, the relative importance of each disease across locations has not been assessed and well profiled to sound management strategy. To determine the occurrence, distribution and the status of in the two zones , survey was carried out in three districts of South omo and Segen peoples zone i.e. South Ari and Benatsemay(South omo zone) and Konsso (Segen peoples zone), in 2013 cropping seasons. Results indicated that 70% of maize sampled plants were infected by Trichometasphaeria turcica at South Ari district of South omo zone. Whereas at Segen peoples zone the heights infected percentage was recorded 45%( Fusarium graminearum) . The current study indicated that a complex of diseases exist at different crops of the studied areas and the occurrence across districts is highly variable despite introduction and promotion of different management practices. Therefore holistic and cumulative integrated approach is required to manage the complex diseases in the surveyed areas.

Highlights

Most farmers in South omo and segen peoples of Southern Nation Nationality Peoples Region plant uncertified seed saved from the previous harvest or borrowed from neighbors or purchased from local markets, factors that encourage spread and introduction of new diseases
Previous studies have revealed the importance of sorghum, maize, haricot bean mung bean cow pea and coffee diseases including anthracnose in the world at large and in Africa in particular (Hulluka and Esele 1992, King and Mukur 1994, and Esele 1995)
Assessment on major diseases of maize, sorghum, coffee haricot bean, mung bean and cow pea was undertaken at South omo zone (South Ari, and Benatsemay woreda) and Segen peoples zone (Konsso woreda)

Summary

Introduction

Most farmers in South omo and segen peoples of Southern Nation Nationality Peoples Region plant uncertified seed saved from the previous harvest or borrowed from neighbors or purchased from local markets, factors that encourage spread and introduction of new diseases. This trend has variously been attributed to prohibitively high prices of certified seeds, unavailability of certified seed; desire to grow new varieties and the fear of losing the traditional varieties that have special attributes (Witcombe et al, 1999; Sperling and Loevinsohn, 1993). Most of the studies do not provide quantitative measurement in terms of
