Killing grass in Myrtle ground cover

[Outdoors_Unlimited]

I have a client who has about 8k sq ft of myrtle beds, that have a lot of grass in them.

I'm wondering what product can be used on this, as her fert company tells me they know of nothing. (She uses TruGreen, and they suck!)

A client of mine found some grass killer, that doesn't affect broadleaf at a local box store... it seems to have worked pretty good , but I don't remember the name of it... in the old days people used 'Atrazine", maybe they still do...

Thanks for the response.

I had seen something at Home Depot, but I'm not a chemical type person. I was looking for some others opinion so I knew what to ask for from an aoplicator. Basically, I like hearing from people other than just the guy trying to sell me something.

You want either Fusilade(Fluzafop, Envoy Plus(Clethodim) or Segment(Sethoxydim) herbicide to be applied to the grassy weeds. The instructions for application down to type of spray equipment and additives needs to be followed. Control failure normally results from sloppy application techniques.

Round up applied to grass only with sponges.
