Interpretive Summary: In 1997, hop powdery mildew, caused by the fungus Podosphaera macularis, was confirmed for the first time in hop yards in the Pacific Northwestern U.S. This review presents a summary of the body of knowledge developed for hop powdery mildew, progress towards economically-sustainable disease management, and future directions for research. The importance of strong public-private partnerships and grower innovations that were essential to successfully addressing an invasive pathogen are highlighted.
