Assure® II Herbicide

Volunteer Corn and Grass Control Improves Establishment, Yield and Quality

One postemergence application of DuPont™ Assure® II herbicide controls volunteer corn and a broad spectrum of problem grasses, giving crops the best start to help them achieve their genetic potential.

Assure® II consistently controls a wide variety of perennial grasses, including quackgrass and johnsongrass, as well as tough annual grasses, including foxtail, wild oats, barnyardgrass, brome species, volunteer cereals and volunteer corn.  Better grass control improves crop establishment, reduces competition, and results in cleaner fields for improved yield and quality, and an easier harvest.

Flexibility to Protect a Variety of Crops

Assure® II delivers exceptional broad-spectrum grass control for canola, cotton, crambe, dry beans, dry and succulent peas, flax, lentils, mint (spearmint and peppermint), snap beans, soybeans, sugar beets, sunflowers and more.
