Kreuser PGR GDD

Dr. Bill Kreuser at University of Nebraska is the leading scholar on plant growth regulator use on cool-season turf, and timing interval for reapplication. In a recent Tweet, Kreuser provided a table of reapplication growing degree days (GDD) base 0 degrees Centigrade. This table provides the same data with GDD base 32 F that PACE Turf uses in Weather Alerts. The ranges represent the amount of suppression and interval in GDD between applications for the low and high rates of each product listed.
