Abstract

Wheat leaf blotch (Zymoseptoria tritici) is economically important foliar disease in major wheat growing areas of Ethiopia. The goal of the current study was to evaluate the effects of sowing dates, varieties, and fungicide frequencies on leaf blotch. In a factorial arrangement of RCBD, four fungicide frequencies with control, three planting dates, and two bread wheat varieties were combined as treatments combination. The highest AUDPC (2502.5) value was scored on the Pavon-76 control treatment at mid –June sowing date during 2020 cropping season, whereas, the lowest AUDPC (290.3) value on the Alidoro variety sprayed four times at early July sowing date during 2021 cropping season. Wheat grain yields were the lowest (0.91t/ha) from unsprayed plots of Pavon-76 susceptible wheat variety during early sowing dates. Alidoro variety treated with three times spray frequencies during late-sowing date produced the highest yield (7.1t/ha). The highest (2776.36$) net benefit was obtained from three times sprayed of Alidoro variety during late June sowing date and the lowest (674.4$) net benefit was obtained from pavon-76 variety without fungicides spray during mid-June sowing date. Therefore, controlling wheat leaf blotch by planting the Alidoro variety at the beginning of July with three fungicide sprays is crucial for Ethiopian farmers. Once more, the wheat pathologist is anticipating additional research including the screening of fungicides and wheat varieties. More study is important to identify the effects of topography and weather on this disease; as well as, the epidemiological study of the pathogen is very important.
