I'm desperately trying to find a herbicide to kill Alternanthera Pungens Kunth, aka Khaki weed. It has to kill the deep taproots and also the leaves and stickers.
No, Trimec Southern Broadleaf Herbicide is not labeled to control khakiweed. Monument is the only herbicide we have that is labeled for khakiweed control in turfgrass. This article suggests other active ingredients that have shown activity on this weed, but we cannot guarantee they would be effective. Based on that article, you could consider Blindside or Changeup depending on your turf type.
