Uses: Topramezone is a systemic postemergence herbicide for control or growth suppression of emerged broadleaf and grass weeds in field corn (grown for grain, silage or seed); popcorn (grown for ear, kernel or seed) and sweet com (grown for ear, kernel or seed). This product may be used on conventional and herbicide resistant/tolerant com hybrids. Topramezone has herbicidal activity against broadleaf weeds and grasses. Its efficacy is the result of the inhibition of the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) enzyme in target plants. Following treatment in sensitive plants carotenoid pigment formation, membrane structure and photosynthesis is disrupted.
