Iowa folks - we are looking for red crown rot in Iowa. If you see something suspicious this growing season please let me or Daren Mueller know or send samples to the ISU PIDC Iowa State Yard and Garden

CPN has added several new tools and resources since last growing season. If you haven’t visited them recently, do yourself a favor and visit their website.
