This publication is available in PDF format only.

Downy mildew diseases occur on several herbaceous plant species, but they do not typically cause severe problems in Virginia landscapes. In the summer of 2012, however, landscape plantings of common garden impatiens (Impatiens walleriana) (fig. 1) in many parts of Virginia  and other eastern states were devastated by a new downy mildew, impatiens downy mildew (fig 2).
