Residental St. Augustine grass
On St. Augustine grass, you will use 0.25 – 1.0 oz of MSM Turf Herbicide per Acre (0.125 – 0.5 oz per ½ Acre), depending on the specific weeds you are targeting per the product label. This should be applied in sufficient water, usually at least 1 gallon of water per 1000 sq ft you are treating.
