What caused my centipede to turn yellow two days after spraying Trimec Southern Broadleaf Herbicide?

I’ve used .5 ounces per gallon for a couple of years now never had this issue. Could it be the temperature being so hot? Also I mowed the grass the following day after spraying. I read one of the question where it stated to wait two days before mowing. Hopefully the centipede grass will pull through.


When applying Trimec Southern Broadleaf Herbicide, it should be applied when temperatures are between 50 and 90 degrees.  If it’s hotter than 90 degrees, it can cause harm to your grass.  Centipede is already somewhat sensitive to the Trimec, so applying it during stressful conditions, like temperature and mowing, can cause harm. Keep in mind when mowing, you should not mow 2 days before application, and 2 days after.
