Participatory Evaluation and Selection of Fungicide Efficacy Against Wheat Rust Diseases on Bread Wheat (<i>Triticum aestival</i> L.) at Highland Area of Guji Zone

Bread wheat (Triticum aestivum L.) is an important cereal grown in the highlands of Ethiopia. Various biotic and abiotic stresses affected production productivity wheat. From stresses, yellow rust stem disease that caused by Puccinia striiformis f. sp. tritici graminis are among devastating bottlenecks. Therefore, a field experiment was done at two highland Guji zone (Bore Ana Sora) under rain-fed condition during 2019/20 main cropping season to evaluate effects different fungicides on diseases, yield components bread The treatments consisted five including standard check nil application using variety Kubsa. A randomized complete block design with three replications used conduct up experiment. partial budget analysis carried out assess financial profitability fungicide for management rusts. Analysis results revealed significantly growth parameters attributes except date heading maturity. Fungicide spray reduced both rusts (yellow stem) diseases severity lowest level increment over application. minimum recorded from test Take-Off 293% SC while maximum were unsprayed plot. There significant difference (p < 5%) grain yield, biomass thousand seed weight, plant height, spike length between control/nil highest (2738 kg/ha) obtained sprayed plots (987 better advantage than Check control about 5.6 63.95, respectively. Moreover, all applications showed considerable untreated plots. controlled effectively increasing based analysis, control, which leads optimum decreasing can be recommended study area other areas similar agro-ecologies.
