Interpretive Summary: Downy mildew is one of the most important diseases affecting the U.S. hop industry. This research was conducted to quantify disease suppression using fungicides with reduced toxicological risk to identify alternatives to current fungicides that may present market entrance barriers in the future.

Technical Abstract: This research was conducted to quantify the degree of control of the disease downy mildew with new experimental fungicides. Varying levels of control were found. These findings will support development of best management practice recommendations for the disease given the development of fungicide resistance and changing maximum residue level requirements in export markets.
