Bermuda Grass Weed

Weed control

An established, well maintained bermudagrass turf will have very few weed problems, but there may be occasions where weed control measures become necessary.

Many brands of herbicide can be used on bermudagrass turf, but certain precautions should be followed. Always read the label completely and follow its directions. Do not apply herbicide when the temperature is above 85°F or when the lawn is under moisture stress. Some herbicides
should not be applied to a newly seeded or plugged lawn.

Preemergence herbicides can be used on a regular basis as a preventative measure to control weeds before they become a problem. If your lawn is in an area that is likely to be constantly subjected to weed infestation from outside (a nearby vacant lot or poorly maintained yard), then preventative herbicide applications may be appropriate.

A wide variety of preemergence herbicides are labeled for home use in bermudagrass. It may be necessary to combine herbicides to control both grassy and broadleaf weeds—use only the mixtures allowed by the respective herbicide labels.

If weeds are only an occasional problem or if your lawn is already infested, then postemergence herbicides labeled for bermudagrass should be used. Check the label to be sure the herbicide is effective on the specific weeds to be controlled.
