The experiment was conducted<br />at the experimental fi elds of the Faculty of Agronomy and<br />Veterinary Medicine, University of Passo Fundo, RS, Brazil,<br />during the summer of 2009/2010. The incidence and number<br />of ureides/cm2, transformed to severity (%) were evaluated.<br />The fungicides applied were tebuconazol and a mix of<br />epoxiconazol + piraclostrobina, at seven developmental<br />stages. Applications made before crop canopy closure were<br />more effective because the fungicides reached the lower<br />part of the plants where the disease starts. The mix of<br />traizol + estrobirulina was more effective tan triazol alone in<br />controlling soybean Asian rust. ER -
