HARRISBURG – In 2012, impatiens downy mildew (Plasmopara obducens) just about wiped
out impatiens planted in the managed landscape.
Now it’s back.
The Pennsylvania Department of Agriculture has found
impatiens downy mildew in greenhouses and garden centers in several regions of
the state this spring.
PDA and Penn State recommend following practices for
controlling impatiens downy mildew that can be found on the Michigan
State Extension website.
