Prevalence, Intensity, and Morphological Variability of Wheat Blotch (Zymoseptoria tritici) in Oromia, Ethiopia

Studies of the wheat Zymoseptoria tritici blotch (ZTB) status in different locations, on agronomic practice, and pathogen variability has not yet been studied Ethiopia. As a result, goal this study was to determine ZTB's distribution intensity, as well morphological isolates. In Oromia's central-southeastern region, zones districts were purposefully chosen, whereas kebeles determined via systematic sampling procedure. generalized linear model (GLM), mean comparison fixed effects examined using least significant difference (LSD) tests. Colony texture, shapes, colors used identify isolate variability. Pearson correlation examine relationship between disease intensity independent variable, multiple regression analysis estimate magnitudes association. A total 108 fields examined, with percent occurrence (88.9 100%) (77.8 recorded. ZTB significantly across (p 0.05) while severity 0.01). Weed infestation (r = 0.78 r 0.20) growth phases 0.72 0.36) had positive correlation, although plowing frequency -0.77 -0.43) negative incidence severity. There are 43 isolates classified into four colors, three textures, forms. The epidemics current research areas need more consideration they should be prioritized for integrated management. Our data suggest that weed control, soil tillage, crop rotation all effective ways mitigate ZTB.
