https://www.domyown.com/remedy-ultra-herbicide-p-11710.html It looks like Turflon has been discontinued at this site. Replaced by "Remedy". You don't need much. Cost is about $1.13 per thousand sqft. For brush control they suggest mixing it with 2,4-D low-volatile ester. On the other hand, at the same site, "Crossbow" offers the Turflon and 2,4-D ester already mixed. https://www.domyown.com/crossbow-specialty-herbicide-4d-triclopyr-p-4545.html Looks like about $1.79 per thousand sqft. Local advice is better. I am 2000 miles from you. Cold here.
