PCP #35335 · Interprovincial Cooperative Limited · Herbicide
Group 2 selective herbicide containing thifensulfuron-methyl (50%) and tribenuron-methyl (25%) as wettable granules for postemergence control of annual and perennial broadleaf weeds in spring wheat, durum wheat, winter wheat, barley, and oats. Controls or suppresses a broad spectrum of weeds including kochia, wild buckwheat, Canada thistle, cleavers, and volunteer canola. Can be applied alone or in tank mixes with other herbicides for expanded grass and broadleaf weed control. Primarily for use in Prairie Provinces and Interior British Columbia.
