Summer Patch Treatment

March 22, 2012

Questions are coming in about the timing of the first application of fungicides for Summer Patch. Usually the recommendations are for the first application to go down when:

  • Soil temperatures are 65°F
  • At a 3 inch depth
  • For 3 consecutive days

Due to the unusual warm weather and the likelihood that a cool down will occur, it may be wise to wait a bit longer for the first application. Also some researchers are recommending waiting until soil temperatures are closer 70-75°F before making the first application.
