Bean anthracnose is an important disease affecting common bean (Phaseolus vulgaris L.) in Hararghe highlands which produces common bean in large areas. The study was undertaken to evaluate the effect of integrated management of bean anthracnose through soil solarization and fungicide applications on disease development and seed health of common bean variety Mexican-142. Field experiments were conducted at Haramaya University and Hirna research station in 2010 summer season. Soil solarization was integrated with mancozeb and carbendazim seed treatments, with foliar sprays of carbendazim at the rate of 0.5 kg/ha at 10 and 20 days intervals. The experiment was arranged in 2×3×3 split-split plot design with three replications. There was significant difference in the anthracnose incidence, severity, infected pods per plant, infected seeds and AUDPC among treatments. Combined effect of mancozeb seed treatment with carbendazim spray at 10 day intervals and carbendazim seed treatment and carbendazim spray at 10 day intervals have reduced severity by 46.5% and 41%, respectively at Haramaya. Interactions of solarized soil with carbendazim foliar spray frequencies at 10 days interval reduced the number of infected pods per plant by 58% at Haramaya and 38.9% at Hirna. In the results concluded that, the integration of soil solarization, seed treatments and foliar spray were found to be effective in reducing bean anthracnose epidemics and seed infection.
