Abstract: Anthracnose (Colletotrichum spp ) is one of the most important disease that decimate chili production in Ethiopia. The efficacy of three Trichoderma isolates viz., AAU-37, AAU-Th and AAU-69 with aqueous leaf extracts Onion, Garlic, Neem and Cassia spp were harmoniously applied on Oda Haro, Mareko Fana and Melka zala pepper varieties, with the aim to manage chili anthracnose in rainy season of 2013. The treatments were arranged in RCBD replicated thrice. Data on disease reaction, quality and growth characteristics of chili had been collected. Analysis of data was carried out using ANOVA. The lowest plant infection (12.8%), leaf infection per plant (15.2%), percent diseased leaf area(15.2%)and infected fruits per plot (17.4%) was observed on combined application of isolates Trichoderma spp, plant extracts and Ridomil in Maraqo fana variety. Regarding the growth parameters, viz. the highest Mean Percent establishment (81.67), mean days to 50% flowering (65.33), mean days to 50% maturity (82) days to first harvest (106.3) in was observed in T16, T16, T4, and T8, respectively. From the quality parameters, the highest mean number of branches per stem (9), mean canopy diameter (24.8), mean number of flowers per plant (9.6) and mean plant height (61.4) in T10, T15, T6 and T7, respectively. Both negative and positive control showed higher incidence and severity as compared to single and combined application of isolates Trichoderma spp, plant extracts and Ridomil. Therefore, integrated use of Trichoderma spp and plant extracts can be recommended. Conventional fungicides will be replaced by antagonists and botanicals. This will improving crop quality and growth maximize profitability of chili and ultimate sustenance.
