The effect of Pseudomonas fluorescence, Trichoderma viride and Trichoderma harzianum on anthracnose was studied at Ambo, Ethiopia during the 2013 cropping season. There were highly significant differences between disease levels and seed yield among bio agent seed treated plots. Anthracnose on beans from untreated seed-planted was more in diseases incidence and severity than on beans from seed treated plots with Pseudomonas fluorescence, Trichoderma harzianum, and Trichoderma viride. Bean seed yield and yield components aspect were also influenced by the bioagents. Lower hundred seed weight, infected pods per plant and seed yield were obtained from seed untreated plots. There were no significant differences in pods per plant and seeds per pod. Highly significant AUDPC of 1529.8%-day occurred in the control plot and 672.2%-day in the seed treated with Pseudomonas fluorescence plot. Management options that highly reduce anthracnose primary inoculum should be promoted indicating that the purpose of seed treatment was to reduce the primary inoculum.
