Is Trifloxysulfuron harmful to corn

It certainly can be. Farmers are not allowed to plant corn after an application of trifloxysulfuron for anywhere from seven to as much as 22 months after application to a labeled crop such as cotton or sugarcane.

Trifloxysulfuron is a herbicide that mainly used for the control of broadleaf weeds and nutsedge sedge weeds in cotton fields and sugarcane fields. It has certain harm to corn, but there is little risk. It belongs to sulfonylurea herbicides and contain 2-Bromo-3-hydroxypyridine. After application, plants can obsorb this herbicide from the roots, stems, leaves. It affects the biOSynthesis of branched chain amino acids(such as leucine, isoleucine, and valine) by inhibiting the activity of acetolactate synthase (ALS). It can be rapidly metabolized to inactive substances in cotton and sugarcane, so that can protect crops from harm.
