Description and Uses

Isoxaflutole is a 4-benzoyl isoxazole molecule and is used as a pre- and early post-emergence herbicide for the control of a wide range of important broadleaf and grass weeds in maize (Zea mays), both in Europe and in North America. It is also registered for use in sugarcane in Central and South America (2–4). It causes characteristic bleaching of newly developed tissues of susceptible species followed by growth cessation and necrosis. Marketed as Balance for corn (maize) in the United States, and Merlin for corn in Europe; and in sugarcane, it mixes well with metolachlor, acetochlor, dimethenamid, and atrazine to complete the weed spectrum and to reduce the application rates of the latter compounds (2). Isoxaflutole also controls triazineresistant weeds in the field (4).

Isoxaflutole is an pesticide used to selectively control both grass and broad-leaved weeds in maize and sugar cane. Isoxaflutole is known to work by inhibiting the enzyme 4-Hydroxyphenylpyruvate dioxygenase (HPPD) which results in the disruption of pigment biosynthesis.
