Faba bean is one of the most economically important pulse crops cultivated in Ethiopia. However, its average yield reported at national level remains far below the potential yield to be attained. This is partly due to low soil fertility management, inappropriate agronomic packages and diseases and pest problems. Hence, this experiment was conducted to investigate integrated disease management methods against major faba bean diseases at Guji Zone, Southern Ethiopia. The experiment was conducted in Songo Bericha on station of Bore Agricultural Research Center during the 2017 and 2018 main cropping seasons. The factors studied were two fungicides (Fungozeb 80% WP at 3 kg/ha and Natura 250 EW at 500 ml/ha), two frequencies, four planting dates at 7 day interval and variety walki. These were laid out in a factorial arrangement in randomized complete block design with three replications. Data on phonological, growth yield and yield related parameters were collected and analyzed using SAS software. The result showed that the highest plant height (140 cm) and 139.2 cm was recorded for spraying fungicide once and Natura alone respectively. The interaction of fungicide sprays frequency, fungicide type and planting date had significant effect on almost all parameters except plant height. Significantly highest numbers of days emergency (14 days) was recorded from late sowing with both fungicide spray, 63.67 days to reach flowering was recorded from early sowing with no fungicide application.  The highest number of total pods per plant (21.27) was recorded at planting date two by application of fungicide Natura twice whereas the highest number of seeds per pod (6.17) was recorded for fungicide fungozeb spray once at mid-planting of faba bean. The highest grain yield (4674 kg ha ^-1) was recorded due to spraying of Fungicide Natura twice. The highest chocolate spot severity (48.4 %) was recorded from faba bean sown at late July, the highest severity Ascochyta blight (46.22%) was recorded at early planting with spraying of fungicide once and the highest severity (19.26%) was recorded from faba bean sown at 17^th July. Thus, it can be concluded that integration of moderately resistant variety with sowing date is proved to be better management option was found to provide good control of the disease severity compared to chemical treatments.
