Got Blackspot?

Got blackspot?  Try spraying with a combination of Maneb (Manzate or Mancozeb also work) with tebuconazole (Bayer Advanced Disease Control for Roses, Flowers & Shrubs Concentrate).  Not Bayer 3 in 1.  Spray at 7 to 10 day intervals to avoid possible phytotoxic effects such shortening of internodes.  Use only as directed!

Bayer Advanced Disease Control for Roses, Flowers & Shrubs Concentrate is available from Amazon.com and DoMyOwnPestControl.com. There may be local sources to the Twin Cities, but I have not found any in the East side of the Twin Cities.
