Bermuda control

If you have been out to the course in the last 2 weeks you have noticed some white turf around greens on holes 5, 6, 7, and 15.  I am using a herbicide call Pylex to kill Bermuda grass out of cool season turf.  All white grass blades you see is the Bermuda grass.  We have a bad problem of Bermuda grass encroaching into our greens.  This herbicide is selective and only targets warm season grasses.  I will need 2 to 3 more applications to completely kill the Bermuda grass.  We will be targeting our collar also.

All white leaves are Bermuda grass.  All green is Fescue and Bluegrass
