Any recommendations for what is the best selective herbicide to use
against Bermuda Grass in a Fescue lawn? I've used Acclaim in the past.
It is fairly expensive and it generally does not completely kill the
Bermuda. It will brown it out and stunt its growth but it does not
eliminate it. My lawn is located in a transition zone where both Fescue
and Bermuda will grow but neither is really optimal for the area. In
fact, I'm not sure we really have an optimal grass. Our summers are hot
and dry enough to seriously challenge most Fescues (though some of the
recent drought and heat/sun tolerant variates are an improvement). Our
winters will get as low as 0 - 5 degrees F every five or six years which
will kill Bermuda. I have elected to have Fescue to have some green in
the winter months (a choice that required an in ground sprinkler system
to be realistic). My neighbors chose Bermuda so I have some
infiltration at our property lines. Fall re-seeding has kept a more or
less status quo but I have seen the Bermuda toe hold in my yard increase
slightly this year.
So, what about it? Any new selective herbicides to address Bermuda in a
Thanks in advance.
Nothing is perfect, and you should not expect anything more than a
significant reduction in the amount of Bermuda in your Fescue.
That said, Acclaim mixed with Turflon Ester is a decent choice, as is
Fluazifop mixed with Turflon Ester. Somehow, the mixes do more damage to
the bermuda and less to the fescue than the single chemical application.
By the way, I have a couple hundred dollars worth of those three chemicals
in my collection. I'm fighting bermuda in my zoysia...
I figure I'll beat it back some year by year. That's about the best we can
do with today's chemicals.
