Growing Degree Days Worksheet

Growing Degree Days (GDD) can allow turf management professionals to monitor heat accumulation, which translates to the development of the turf. By tracking GDD days, you are able to refine product application timing based on actual weather patterns in your area rather than a pre-determined calendar-based schedule.

The model estimates when the growth suppression phase is ending, to position an application before turfgrass has a rebound of growth.

By using GDD you can make applications at timings that maximise the positive effects of PRIMO 250 EC and PRIMO MAXX.
