Answer:

Yes, Southern Ag Atrazine Weed Killer for St. Augustine Grasses is able to be used on St. Augustine Floratam lawns. It is both a pre-emergent and post emergent and is best applied when weeds are small or have not yet emerged. Pre-emergents are meant to be applied in early Spring and late Fall before the weeds have started to actively grow (when temperatures are 60 degrees for 4-5 consecutive days). Please follow instructions per the label. With Floratam St. Augustine grasses being extremely sensitive to post emergent herbicides, weeds that have already broken the surface of the lawn should be removed manually either with a weed whacker or by hand.
