We are using two different chemicals this year. We are using Ronstar in some of our weaker turf areas and on tee boxes because it is safer on these areas and will allow the turf to fill in throughout the growing months while still providing excellent weed control.
The other product we are using is Specticle. It is a great pre emerge for all types of weeds. We sprayed it last year at this time and we feel like we got pre emergent weed control all the way through the fall and into the winter. Everywhere we sprayed Specticle, we didn't have a single bit of Poa Annua germinate this fall. This is a great product.
Another thing we are doing is adding a Glyphosate (active ingredient in Round Up) product in with our chemical. This is going to clean up any weeds that have germinated over the winter. Since it has been so cold, the Bermuda grass is completely dormant and this will not harm it.
