Viridian is a newer version that is also called Texas ProVista and is a deeper green color and more cold tolerant.

Actually Floratam. Pour glyphosate throughout your lawn and see what happens. Have fun with that

I have used glyphosate a numerous times on my ProVista and the only thing it killed was the weeds. Floratam was developed by the University of Florida and Texas A&M University hence the name. Scott's developed ProVista to be resistant to the Scott's/Ortho product Roundup which at the time contained glyphosate.

A quick Google search will show you these facts.

I did a lot of research and found the best killer of torpedo grass is 'Quniclorac' or Drive XLR8. I bought both online months ago along with a substance to allow the mixture to stick to the leaves. And a nice powered sprayer. Did about 3 applications over the last 10 weeks or so (2 week intervals). Was out of town the last couple weeks, and, the torpedo grass is back with a vengence. I know that it takes time and more applications, but...I think I'll now give up the DIY. I really don't trust 'lawn care companies' a lot, but now I guess I'm in search for the best. We have used Dean's before for our lawncare, fert and cutting. But it's been years now.

Perhaps I will get a lot of generic feedback - but I would like to get names of a few VERY REPUTABLE firms around The Villages to help me eradicate this stuff. Only getting worse.
OR - at the proper time, take out all the affected zoysia in front and put in new zoysia sod.

Please help... TIA

We are fighting nature. Nature always wins. One type of grass neatly edged is not natural.

Accepting that. Torpedo grass is tough. If, you pull it, it grows from any root you leave be- hind. Solution is applying one of the kills all weedkillers to the torpedo grass with a paint brush.
