Use the GDD Tracker for Poa annua Suppression

The winter of 2016-2017 has been mild to say the least. With recent record-breaking temperatures, the time is now to start seriously considering applying your poa seedhead suppression application. Plants don't abide by human calendars. If the environment is telling them to grow, then grow they will.  

At the time of this article, the total GDD (growing degree days) in Cook County, IL was 123.  Poa annua seedhead suppression apps should ideally begin a little over 200 GDD. If you don't know your GDD, go to gddtracker.net and enter your zip code. This gives you a quick and easy way to help plan this application. I am a firm believer in applying this application on the early side. If you wait too long, your application becomes less effective. Monitor your GDD, get your sprayer up and running, and apply Proxy to your target areas. If you wait too long, you will regret it.
