Over the past couple weeks we have been able to evaluate the effectiveness of our Poa seed head control. The 2 main things that can effect control, are the products being used and their application rates, and most importantly the timing of application which is based on growing degree days (GDD). This year we have had great success controlling the seed on greens approaches and fairways. The grass has started to grow out of regulation and it is visibly apparent where seed is present. The photo shows #14 fairway with a distinct white line of seed head, where the rest of the fairway was sprayed and has a nice green grass appearance. You will also notice seed head in the second cut of rough on the edge of fairways where applications ended.
