Just sprayed about 10-11 acres of Bermuda eradication spray earlier in the week. I sprayed 4 acres during the first few years, 8 last fall and have increased again this season. The longer I delay the spray, the bigger foothold the Bermuda will have and the greater potential for winter kill we could face like this past spring. I'm just seeing some of the patches begin to turn a little off color. By middle of next week you should see most of the patches and full areas that I sprayed. There are some areas that have less and other areas that have more Bermuda since last season. We will sod a couple of pallets of sod where necessary and will allow the rest to come back in time for the Echofest the 2nd week of September. I will then spray again to set more of the Bermuda back going into winter. I sprayed a slightly lighter rate than in the past in an effort to reduce the negative effects on the zoysia since it is growing nicely right now.
The fairways that have been in the program the longest are 4,7,8, and 13. They were sprayed in the fall of 2009 for the first time. Four has some larger patches that are making a comeback and these could be prime candidates for sod work but overall, the amount of Bermuda in the fairways listed above is less than the others with the exception of 200 yards to the green on #7 which I only began to spray last season.
There are some low drainage areas and other spots which will probably never be sprayed because of zoysia's inability to grow in these areas. David Stone, long time superintendent from the Honors Club in Tennessee told me a couple of times during our discussions about Bermuda removal that sometimes even though we might not like it, Bermuda is the best turf for that area or situation.
I did also spray a few tees that I thought would be less negatively effected. I will give you a more detailed report next week when the areas become more visible.
