Centipedegrass is pretty finicky. It is sensitive to different herbicides and sensitive to too much herbicide (think overlaps, etc). It is also sensitive to winter kill and doesn't go fully dormant in most of the US, so I don't like to treat it with anything while it's not fully green. I've even seen half rates of herbicides labeled specifically for centipedegrass do damage when applied when the lawn is off-color. My best advice would be to use this as an opportunity to get the customer to switch to a better turf species.

As for glyphosate, it has no root uptake. It is taken up through translaminar activity, then translocated throughout the plant. I can't stand the misnomer about "kills to the roots." Either it kills or it doesn't. Glyphosate interrupts the shikimic acid pathway, which allows the plant to make different armoatic acids, specifically tyrosine, tryptophan, and phenylalanine.

H 2 the nizzo! You'll end up with a lot of dead grass come spring.

I am on the northern edge of the zone where Centipede can survive winter. It does not go completely dormant here. Neither does St. Augustine. Both are stoloniferous turfgrasses so most of the plant parts are above ground. This is also why they are not cold tolerant. If you get down and pull the turf back, you will probably see lots of green.

Years ago I made the mistake of spot spraying R-up in zoysia which also doesn't go completely dormant. It knocked the turf for a loop(heavily thinned) in those areas and took some time to recover. Zoysia is slow to recover though.

IMO, at the very least, you've knocked the turf for a loop. Worst case scenario, you smoked it.

That's why professionals carry insurance. Good Luck.

Luckily it's a commercial property and not somebody's home lawn. Worst case scenario I'll just patch up the dead spots in the spring with sod.

I will let you guys know how it turns out.

That's great that you didn't do a broadcast app. Picky homeowners are definitely more likely to notice thin/dead spots and be less understanding for sure. Hope all goes well. Please do let us know how it turns out when the turf greens up. You'll know exactly where you stand then. I'd like to know just out of curiosity.

At least it's commercial property but I'd bet the centipede suffers pretty severely.

I have sprayed round up on dormant grass about 15 years ago I will never do it again... too much explaining to do come spring time. Go buy a bottle of Celsius
that stuff works great on everything at anytime.
