Question

My lawn service spread Drive on my Floratam St. Augustine Lawn to kill crabgrass. I was told that it might make the grass turn yellow for awhile, but that the grass would come back good as new. A few days later the grass started to brown and now is mostly dead. I note that you do not mention St. Augustine grass in your usage description. Is that because it is unsuited for such use? Will Drive kill St. Augustine as i've described? Is the result of such usage intensified by Florida August heat? Ed R., Deland, FL

Answer

Everyone has questions. And BASF Professional Turf has answers.

Dear Ed: Our BASF label does not recommend the use of Drive herbicide on St. Augustinegrass. The weather conditions typical for Florida in the summer months does not make a difference for this recommended use. We state on the label under Turfgrass Tolerance that St. Augustinegrass is susceptible to the herbicide.
