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 effective disease control may be possible without use of certain fungicides that may present trade barriers in the European Union export market.
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, especially in light of pending MRL revocations in the European Union.
