You may have to check with an actual agricultural supply / spraying company, to find it, Sherry. I know our local nursery *used* to carry it, but no longer does, as the "state regulations" have changed. If you use it, or, any of the 'high powered" chemicals (especially in the powdered form!) be sure to wear a mask, gloves, and such...and follow the directions !! Argistrep has been proven to affect the auditory nerves, and going deaf wouldn't be a good 'trade off" !
