        Downy mildew is the most wide spread and destructive disease of hops (Humulus lupulus) in the Midwest and Northeastern United States. Downy mildew is caused by the fungal-like pathogen Pseudoperonospora humuli and is most severe during wet weather and mild temperatures. The disease is systemic and can cause significant yield and quality losses annually. (PLPATH-FRU-49)
