Can MSM Turf Herbicide be used on St. Augustine to treat woodsorrel, bermudagrass and nutsedge?

Answer:

MSM Turf Herbicide is labeled for wood sorrel and is safe to use on St. Augustine grass.  It is not labeled to control nutsedge so we would recommend using a product such as Sedgehammer to treat for nutsedge. For bermudagrass in St. Augustine, there is not a selective herbicide that would kill the bermudagrass without also injuring the St. Augustine. It is recommended to spot treat areas of bermudagrass with a glyphosate herbicide such as Roundup and then reseeding/resodding any bare spots after 2 weeks. Do not make applications in Spring if your turfgrass is transitioning in or out of dormacy. Allow for complete green up and apply in Summer, Fall and Winter only.  View our St. Augustine Lawn Maintenance Guide for more information.
