Powdery mildew of hop (Podosphaera macularis) may cause economic loss due to reductions in cone yield and quality.
Quantitative estimates of crop damage from powdery mildew remain poorly characterized, especially the effect of late season
disease management on crop yield and quality. Field studies in Washington State evaluated cone yield,...

Hop (Humulus lupulus L.) production recently has expanded across the United States to
include areas of the country that have not previously grown hop commercially. In June
2015, a grower in western North Carolina detected powdery mildew in a small (<0.5-ha)
yard during routine scouting. Characteristic signs of powdery mildew...

Podosphaera macularis, the causal agent of hop powdery mildew, is known to produce chasmothecia (formerly cleistothecia) in eastern North America and Europe. Ascocarps have not yet been reported from the Pacific Northwestern region of North America. Reasons for the apparent absence of chasmothecia in the Pacific Northwest were unknown. This...
