Latest Updates

May 19th, 2020Weather Data Interruption

We are currently experiencing problems with tracking growing degree days at GDDTracker.net. The weather feed we rely on from NOAA has been discontinued and is being migrated to a new server. We hope to be able to resume counting growing degree days in the next week or so. Thanks for your patience and understanding.
 

February 17th, 2020Welcome to the 2020 GDD Tracking Season

February 15th marked the start of our 3rd decade counting growing degree days here at GDDtracker.net. What started out as a couple models to schedule plant growth regulator applications to suppress annual bluegrass seedheads has expanded to include models for crabgrass germination, early season DMI fungicide applications, and most recently the Smith-Kerns dollar spot prediction model. We've been making some changes behind the scenes with the servers that continually process the immense amount of data collected daily to ensure system stability in the future. Thanks for your support as we look forward to the 2020 growing season.
