Epidemiology in the Garden

This comes from the blog of Brooke Edmunds at Colorado State University. She posts monthly reports of problems that are being seen in the Hort industry.

Host-> Problem diagnosis
  • Bigflower Coreopsis -> Tomato Spotted Wilt Virus (TSWV)
  • Butterfly bush -> Environmental stress (undetermined-possible high salt level)
  • Calibracoa (Million Bells) ->Tobacco Mosaic Virus (TMV)
  • Gerber Daisy->Tobacco Mosaic Virus (TMV)
  • Osteospermum->Environmental stress (undetermined)
  • Pepper transplants -> Pythium root rot
  • Pepper transplants ->Tobacco Mosaic Virus (TMV)
  • Petunia->Tobacco Mosaic Virus (TMV)
  • Tomato transplants -> Environmental stress (High soil pH and salts)
  • Tomato transplants ->Environmental stress (undetermined-possible phytotoxicity)

    If your plant wilts and falls over, or gets suspicious spots, you might do a search for these diseases.
