Interpretive Summary: Powdery mildew is a threat to sustainable and profitable production of hops in the western U.S. This research was conducted to quantify disease suppression and develop overall management programs for the disease using newly registered, experimental, and reduced-risk fungicides. The research suggests that utilizing the most effective disease control products in the final 6 weeks of the season is critically important for successful suppression of powdery mildew.

Technical Abstract: This research was conducted to quantify the degree of control of the disease powdery mildew with newly registered, experimental, and reduced-risk fungicides. Varying levels of control were found. These findings will support development of best management practice recommendations for the disease.
