Scald is an economically important foliar disease in the major barley-growing areas of Ethiopia. The current research
was conducted to determine the impact of barley varieties and tilt fungicide spray schedule on disease development
and barley yield. The effect of barley varieties and fungicides spray schedule on Scald development and barley
yield was evaluated at Holetta in a factorial field experiment involving three barley varieties and four fungicide
spray schedule. Variety Savini had the highest AUDPC (4762) value followed by Ibon (1888) and HB-42 (1402)
varieties. Scald severity were significantly reduced by the application fungicide across varieties. Barley grain yield
were the lowest from unsprayed plots regardless of variety. Tilt fungicide spray produced the highest yield (3.77t/
ha). The highest (7131%) and lowest (0%) marginal rate of return wer.. View more»
