ABSTRACT
ABSTRACT: Coffee arabicais the key cash crop and top mainstay of the Ethiopian economy and requires sustainable production methods.Coffee wilt disease is one of the reasons for the reduction in coffee productivity as well in the livelihoods of millions involved in cultivation, processing, marketing, and export of coffee. The major causative agent of coffee wilt disease is Fusariumxylarioides. Trichodermaspecies are known for the effective control for this particular pathogen. In the present study;Trichoderma species were isolated from the soil sample taken from Jimma and the antagonistic efficiency of Trichoderma isolates against Fusariumxylarioideswas confirmed, using dual culture method. Trichodermaisolates significantly inhibited the mycelial growth of Fusariumxylarioidesranging from 83.08% - 81.14%, after 6 to 10 days of incubation at 25 o. Trichoderma isolates showed successful antagonism against the test pathogen (Fusariumxylarioides).
