Abstract
The ability of triadimenol and rhizobacteria to control the powdery mildew of barley caused by B. graminis f.sp. hordei [ Erysiphe graminis f.sp. hordei ] were investigated in field conditions in Turkey on eight barley cultivars with different resistance genes, namely Bornova 92, Bulbul, Gem 8889, Orza, Tokak 157/3, Yesilkoy, Yercil 147 and Yildirim. The pathogen was isolated from the diseased plants in the fields. Rhizobacteria were isolated from the healthy barley plants via dilution method and applied to seeds and leaf surface when plants were in the first or second leaf stage. Application of rhizobacteria alone gave the best control in Bornova-92, Yercil and Yildirim by 26.96, 13.92 and 17.65%, respectively. Triadimenol and rhizobacteria combination controlled the disease by 60.31-72.89% while triadimenol alone prevented the disease by 58.25-65.34%. Protection in both treatments showed variation in tested cultivars (P<0.05). Disease index was found lower in barley cultivars with more than one resistance genes
