Yet another what's this ugly/different grass thread!

Chemical control. Presently only one herbicide available to homeowners, Tenacity (active ingredient mesotrione), provides selective control of nimblewill in cool-season lawns such as Kentucky bluegrass, tall fescue, fine fescues and perennial ryegrass. Application rates can vary so follow label directions. It is not approved for use on warm-season grasses such as zoysia grass. Several applications are needed for good control and a non-ionic surfactant should be added to the mix. Nimblewill will become bleached and white as it dies.

A cheaper control method is to apply a non-selective, post-emergent herbicide such as glyphosate (Roundup) to patches of nimblewill and then replant the areas. Apply the herbicide when the nimblewill is actively growing during the summer. Applying in late autumn to early spring when it is dormant will not provide control. Glyphosate, being a non-selective herbicide, will kill desirable lawn grasses as well.

Sounds good. You should author the product label.

So do some people have pure Nimble lawns because the weed was never treated?

2 of the yards I used to mow were. I had to stop because I kept moving it to other yards.

Did the 100% Nimble Lawns look good? Maybe I should not have sprayed the 25% of my lawn.

Here is 15% of the lawn from far away and NOT treated (yet) with Tenacity®:

The color difference is noteworthy, but neighbors say it's the best lawn in the neighborhood.
