A selective herbicide used principally in rice cultivation to control broadleaf weeds and grasses. It is applied to flooded paddies according to label rates and timing, with defined intervals before harvest to keep residues within legal limits. Like all crop-protection chemicals, its use is governed by registrations that specify approved crops, application methods, and maximum residue limits in the harvested grain. Monitoring programs test rice against these limits, and growers follow good agricultural practice, including buffer zones and record-keeping, to protect consumers, workers, and the paddy environment while maintaining effective weed control.
