About Topramezone Technical

Topramezone technical is a selective post-emergence herbicide in the pyrazolone class, primarily used to control broadleaf and grass weeds in corn, soy, and other cereal crops. Topramezone Herbicides inhibit the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD), disrupting carotenoid biosynthesis in target plants. This...
