Agriculture has been doing this for Years along Fence Lines and between Trees in Citrus Groves. Progressive Road & Right Of Way contracts for both State and County are now Chemically mowing Bids. Etc Etc I cut my own Bremuda lawn last year 8 times and was never over 6 inches tall. There are drawl back like stripping if you don't pay close attention to details.
John Franz PhD worked in R&D for Monsanto and formulated Glyphosate as a Growth regular that later became the most Financial successful Pesticide ever. BTW It was discovered as a Non select by MISTAKE.
PS Remember Roundup will kill sand spurs but it will not remove them from your lawn. The Dead spurs can still stick you and reseed them self.
So you actually used the Glyphosate right on top of the grass a couple of times per year? This doesn't kill the bermuda or it won't the Bahai? Interesting.
Do you have to get the Bahai pretty well established first?
