Assure® II Gives Growers In-Crop Control of Foxtail Barley

Assure® II is most effective herbicide to control foxtail barley in canola, flax and pulses, setting stage for cleaner wheat crop, say weed researchers.

Mississauga, Ontario – April 4, 2011 – Foxtail barley has been added to the DuPont™ Assure® II herbicide label, giving producers in Western Canada an excellent way to manage this widespread weed. Assure® II is an excellent in-crop solution for canola, flax, and pulse crops, providing 99 per cent control of foxtail barley. That allows growers to seed into cleaner fields when wheat comes up in the rotation.

“There are no selective herbicides available to control foxtail barley in wheat,” says Andrew Stone, product manager for DuPont. “Assure® II benefits growers by giving them a way to manage this prolific weed within their weed control system and crop rotation.”

Foxtail barley thrives in a minimum-till environment. Since it germinates in the fall, foxtail barley emerges early in the spring making it difficult to control with a spring application of glyphosate alone. Assure® II is an excellent in-crop solution to control this weed.
Weed researchers such as Ken Sapsford of the University of Saskatchewan say that Assure® II is an excellent way to control foxtail barley. “From what I've seen and tested, Assure® II is one of the most effective post-emergence herbicides for control of foxtail barley,” says Sapsford.

Foxtail barley is a prolific seed producer and getting control of the weed is usually a multi-year process to decrease the seed bank, including fall and pre-seed applications of glyphosate and in-crop applications of Assure® II.

Foxtail barley is added to the Assure® II label at a rate of 0.5 L/ha and provides 99 per cent control at the three- to four-leaf stage of the weed and 97 per cent at the one- to three-tiller stage.  Assure® II also controls volunteer wheat, durum and barley, and has excellent wild oat and green foxtail control. It has excellent crop safety and a wide window of application. It's also registered for aerial application.

Assure® II is registered for use in canola, camelina, chickpeas, creeping red fescue (for seed production), dry common beans, flax, industrial hemp (fibre production only), lentils, peas (field and processing), seed alfalfa, seedling legumes (seed production), soybeans, snap beans and sugar beets.
