Net blotch is one of the most important barley diseases which reduce both quality and quantity of barley grain. Currently, the disease can be controlled using different approaches. The aim of this work is to test the effectiveness of different fungicides. Progress250 EC, Rexdou, Tilt 250 EC, Skyway Xpro EC 275 and Zantara EC 216 against net blotch of barley disease compared to unsprayed control. The experiment was conducted in west Showa Zone at the site which is well known as net blotch disease hot spot. The experiment was conducted on plots of 25m2. The results showed that, significant (P<0.05) difference among treatments. Skyway Xpro EC 275 fungicide reduced the incidence, severity, grain yield loss, by 79.78, 88.98, and 49.97%, over fungicide unsprayed treatments, respectively. Zantara EC 216 was the second most effective fungicide to reduced disease incidence, severity, grain yield loss, and dry biomass loss by 57.33, 75.58, 36.21, and 38.11%, respectively. The Effectiveness of Skyway Xpro EC 275 and Zantara EC 216 for the control of barley net blotch disease revealed 18.88 q/ha and 10.73 q/ha, respectively, compared to fungicide unsprayed treatment. It is evident that, the newly introduced fungicides (Skyway Xpro EC 275 and Zantara EC 216) control the net blotch disease of barley effectively compared to the previously used fungicides under Ethiopian condition. Therefore, those fungicides recommended for barley net blotch disease management practices as foliar application.
