Study on Fungicide Rate for the Management of Septoria Tritici Blotch (Zymoseptoria tritici) of Bread Wheat (Triticum aestivum L.) in Ethiopia

This research was conducted with the aim of determining the fungicide's rate (Tilt) on wheat varieties with different level of response to Zymoseptoria tritici blotch. From the result of this study, there is significant difference between bread wheat varieties with ZSTB reaction. The highest final disease severity (93% and 83.5%) and AUDPC (576.19% and 506.7%) value recorded on Pavon 76 & Alidoro Variety without fungicide application; whereas the lowest final disease severity (49.0% and 65.5%) and AUDPC (278.3% and 464.8%) value recorded on Alidoro and Pavon 76 variety sprayed with 0.75 lt/ha, respectively. There are significant differences between different Tilt fungicide rates with ZSTB reaction. Among all treatments there is significant difference on yield, thousand kernel weight and hector-liter weight. The highest yield (4.13t/ha and 3.58t/ha), recorded on rate-75%; whereas the lowest (2.97t/ha and 2.06t/ha) recorded on untreated plot from Alidoro and Pavon-76 varieties, respectively. Among fungicide spray dose there is highly significant difference between sprayed plots versus unsprayed plots regardless of spray rates. From this we have concluded that the interaction of Tilt 250 EC with Alidoro which is moderately resistant variety was very effective to manage wheat ZSTB disease.
