The picture below is of hole #13 with the application made about 10 days ago. The application was not made in total in the fairway but was spot sprayed to reduce the effects of the chemical on the non-bermuda areas of zoysia. Zoysia is tolerant to the chemical which means it will not be killed by the products but will yellow and will not be as vigorous during the first couple of weeks of application. We also sprayed the rough on the left side all the way to the cart path and on the right side about 30'. You can see some slight discoloration in these areas. Most areas of our first cut of rough were sprayed from cart path to about 30-40' on the opposite side of the fairway.
The next picture is from September 2008. During this application, we sprayed the entire fairway and the rough was sprayed with one of the two chemicals we were using. This application was made a couple of weeks earlier than the 2009 application which is why the rough is slightly more off color in last year's picture. We have made 3 applications on the rough on #13 and I believe we are beginning to make some very significant impact to this area. This view below is looking down 13 fairway and demonstrates the the effects that the material has on the zoysia and the bermuda. The zoysia turns off color/yellow and the bermuda turns red. As we continue to reduce the size of our bermuda contamination, the squares will be significantly reduced and our zoysia will fill in the voids left by the bermuda turf. The darker green turf in the fairway is where we did not spray the chemical mixture.
