You sure can use Hi Yield Atrazine to treat weeds in St. Augustine grass. Depending on what you are treating will dictate when to apply this product. For example, Apply this product in early April followed by a second applicationin July. Note:Applications for Spurweed or Florida Betony generally will give control or suppression of the other listed weeds. However, as a general rule, this product will give best control when applied to young tender weeds or just prior to weed emergence. Please follow the product label to application instructions.
