Authority Edge controls a wide spectrum of weeds including waterhemp, Palmer amaranth, pigweed, kochia and foxtail. The new herbicide is effective against ALS (acetolactate synthase), triazine, HPPD (4-hydroxyphenylpyruvate dioxygenase), glyphosate and PPO (protoporphyrinogen oxidase) herbicide-resistant weeds.
