Late blight (Phytophthora infenstans) disease is one of the most devastating potato diseases world-widely which causes significant loss in production. It is known to hurt the highest losses from disease attacks. Among potato diseases bacterial wilt and late blight are one of the most economically important. In Ethiopia yield loss study on potato late blight was very old and scanty. This study was designed to update yield loss data for potato late blight disease. In this study, 3 treatments were used with a completely randomized block design (RCBD) with 3 replications including the control. The results of AUDPC and tuber yield shows significant differences (P<0.05) among treatments. Compared to the unsprayed plot fungicides significantly controlled the disease at both early and late stages. The lowest (175.0) AUDPC was recorded on fungicide Gachena 525 WG sprayed treatment followed by Mancozeb 80% WP (190.0). The control treatment (water sprayed) had the highest AUDPC (1450.0). The highest (29.3 t/ha) mean tuber yield was obtained from the fungicide Gachena 525 WG followed by the standard fungicide (Mancozeb 80% WP) which gave (27.2 t/ha) whereas the control treatment gave 4.9 t/ha. The fungicide subjected to the test (Gachena 525 WG) deserves to be considered as an alternate fungicide to the widely used fungicide Mancozeb 80% WP in the country. The highest (83.28%) yield loss occurred in the unsprayed plots of the Jalene variety as compared to the best-protected plots sprayed with Gachena 525 WG fungicide. Generally, disease and yield parameters indicate that among the fungicides spray; Gachena 525 WG was the most effective followed by Mancozeb 80% WP sprayed plots as compared to the unsprayed plots.
