Authority XL is a combination of Authority and Classic. Authority active ingredient is sulfentrazone with others added to make other products like Authority First/Sonic which is First Rate added and Authority MTZ which has Metribuzin added. In your area I would look at Authority Elite or Authority Maxx.
