Trimec Southern combines three active ingredients, MCPP, 2,4-D and Dicamba for an effective broadleaf herbicide for southern grasses. The formulation in Trimec Southern minimizes the risk associated with southern turfgrass. It controls over 90 different broadleaf weeds, including clover, dandelion, and spurge. It is exceptional on clover and chickweed.
Generally as describedApplied this relatively late in the growing season to a residential Bermuda lawn (warm season turf) that was overtaken with four specific types of broadleaf weeds the label says it controls. I heeded the label warnings and applied at the lower concentration.
The biggest benefit of applying this seems to be it stopped the weeds from propagating further and taking over even more of the turf.
In regards to the weeds that were already there, it took about a week for them to start showing signs of yellowing and some types responded better than others. After 2+ weeks, the dying weeds are still in the turf, and have not shriveled up or anything - they take up just as much space as before. The yellowed weeds remain rooted to the soil, and don't dislodge via either mowing or raking. However, they are now VERY easy to pull out by hand, so in some of the more infested areas, I have done that. Removing the weeds gives the Bermuda space to grow and fill in.
I would recommend applying this as early in the growing season as possible, both to stop the weeds from spreading, at which this product seems to be very effective, and to allow the weeds time to totally die and perhaps dislodge (which may happen in time if their root system gets weak enough), so the turf has plenty of growing season time left to fill in where the weeds were.
Gave the product a 4 out of 5 as it definitely kills the weeds, and stops them from spreading. It yellows them and they remain in the lawn. If it caused them to shrivel up, to give the Bermuda space to fill in, I would have given 5 out of 5.
