    Is there a application that I can use to get rid of Bermuda grass without affecting Fescue...?

    Turflon Ester is suppose to help control it.

    Turflon tankmixed with Acclaim Extra - 3 apps 1 mo apart in the summer/active growing months. Turflon w/Fusillade II (Ornamec) also works well - apps in spring and late summer.

    I've done both and had success. Trials I've seen seem to indicate that Acclaim/Turflon mix can be more consistent - plus I can spot treat any other grassy weeds while I'm at it. Both mixes can produce control rates of 90%+ in trials I've seen, but really dependent on site conditions/variables.

    Thanks for the info. I have a potential customer that inquired about getting rid of a area of Bermuda grass that is creeping it's way into the neighbor's lawn. I don't have a license to apply and want to know that my weed control guy is on the ball, if you will. I in no way will do any application work without a license, it just ain't going to happen. Last thing I need is a hefty fine to go along with all the other expenses in the business. I'll leave it to my go to fert and squirt guy that does all that part. Besides, he doesn't cut lawns, all he does is chemical application so we feed each other with potential work. It's a win win for both of us. :)

    If it is an area that is primarily bermuda - then glyphosphate it. Just make sure that it gets hit 3 times ~2-3 weeks apart while its actively growing. I've read where the kill percentage gets up to 90+% consistently/permanently vs. 1-2 apps. Of course, now you've got a dead spot during unfavorable conditions for cool-season grasses....but you should be able to sell some seed/fert. The selective route is more of a "control" but after a 2-3 year program, it's gone.

    Acclaim Extra plus triclopyr/2,4-D ester is the best with 2-3 applications in the summer. Triclopyr acts as accelerator agent with no actual herbicide effect.

    Partially true. Triclopyr is also an antidote for the phytotoxic effect of a "fop" herbicide on tolerant grasses. I had lots of problems applying fluzafop on zoysia for bermuda control until I tank mixed with Turflon Ester.

    Perfect advice. This is exactly NCSU's recommended "method of attack".

    By the way, take the winter time to mark your bermuda spots in the yard. Since the bermuda goes dormant, it should be the only "white" grass in the fescue turf. If you don't have to spray the entire yard next summer, save your money.

    There is a problem with the Fusilade label and summer applications as July and August applications are not recommended.

    Original question was about bermuda control in fescue which leads to Acclaim applications during summer.

    This issue was covered by Dr. Fred Yelverton, NCSU Weed Scientist at a meeting this week.

    Applications with Fusilade would have to be spring and fall.

    I don’t think you would want to add the 2,4-D in the mix since it is antagonistic with the Acclaim.

    Triclopyr also reduces the “bleaching” effect caused by mesotrione.

    I would agree, but I tried an experiment this year. I sprayed full rates of Ornamec + Turflon ester over a 80% bermuda / 20% fescue stand in August and did not see any signs of phyto’ on the fescue; granted I sprayed a couple days after a rain shower, in the evening, about 70 - 75 degrees. I noticed bermuda discoloration in 2 to 3 days, and total kill took about 3-4 weeks (not much rain).
