Effect of timing of fungicide application to manage sclerotinia stem rot in canola

Abstract

Key findings •• Sclerotinia stem rot levels were reduced with a single foliar fungicide applied at 10% and 30%, and multiple applications at the 30% and 50% bloom stages. •• Multiple applications at the 30% and 50% bloom stages had the most significant effect in reducing disease. •• Significant yield benefits were measured when multiple fungicide applications were applied during the growing season.
