Bermuda encroachment, dont pull the runners

Early heat in June has sent our warm season grass into hyper growth, including the dreaded bermuda. There are no safe control measures to use in the summer heat on our bentgrass collars and green surfaces. We will begin chemical treatments in September and will be seeding and replacing sod where possible. PLEASE DO NOT PULL THE RUNNERS. IT DOES NOT LOOK GOOD AND IT IS THE TURF WE HAVE AT THIS TIME. Thanks for your cooperation.
