Technical Abstract: The potential for improved management of Cercospora leaf spot [CLS (Cercospora beticola)] using the herbicide glyphosate in glyphosate-resistant sugar beet varieties was investigated. Controlled field experiments were conducted in 2008 and 2009 to determine if glyphosate and glyphosate-fungicide combinations improved the management of CLS in four commercial varieties of glyphosate-resistant sugar beet. Variety and fungicide main effects were significant for CLS development. However, regardless of the herbicide program, either glyphosate or a conventional herbicide program, CLS development was not affected. Therefore, results from this research indicate that glyphosate and glyphosate-fungicide combinations do not significantly contribute to CLS management in sugar beet.
