FreeHand 1.75G Herbicide will safely prevent Doveweed from emerging in centipede turf. BlindSide is a very effective post-emergent herbicide that will kill existing doveweed in sensitive grasses such as centipede.
The FreeHand 1.75G Herbicide label recommends using a broadcast spreader to apply the herbicide. We would recommend contacting Scotts directly or the manufacturer BASF for a drop speader settings. BASF can be reached at 800-526-1072.
FreeHand 1.75G Herbicide is best applied when the listed weeds have not emerged. For application times, please contact your local Master Gardner in your area by clicking the link below for contact information.
