The first picture is of #10 fairway Newport. We treated this fairway with the herbicide Revolver late last spring. Note how clean the fairway is. The next picture is of #8. We did NOT treat with Revolver. We were unsure of the bermudagrass populations on #8. Now that I know the populations, part of our winter maintenance of the Midlawn Bermudagrass on Newport is treating with RoundUp while the bermuda is dormant. RoundUp at low levels (24-32 oz per acre) controls the cool season grasses and poa annua. We applied a poa preemergent last September. The third photo shows poa annua germinating in a divot. the RoundUp controls the poa and ryegrass without harming the bermuda. I used a green dye to prevent overlaps and skips. The RoundUp was dry and safe to play on in about two hours. I have extensive experience with this type of maintenance. It is part of our effort to improve fairway conditions on Newport. With the lowest possible use rate (24 oz/acre), we should see some results in 2-4 weeks. The RoundUp absorbs slower into the plants during even this mild winter. The efforts done now, will pay huge dividends this season!
