Small grains producers have access to two new broadleaf weed herbicides from Dow AgroSciences. Both CleanWave and Starane NXTcp herbicides recently received EPA registration and Dow is seeking several state registrations for the 2006 growing season.

Jim Parker, senior marketing specialist for Dow AgroSciences, says CleanWave is ideal for growers utilizing continuous wheat and wheat-fallow systems in the Western Plains. Parker adds that Starane NXTcp will be more of a niche product in the Northern Plains where the ability to rotate to any crop the next year is a key need. Starane NXTcp is expected to have a broader appeal in the Pacific Northwest where rotational crops like potatoes, lentils and field peas are abundant.

CleanWave controls more than 30 broadleaf weeds

CleanWave herbicide is a premix of aminopyralid, a new active ingredient, and the proven active ingredient fluroxypyr. Aminopyralid was registered under the EPA’s Reduced Risk Pesticide Initiative.

CleanWave controls more than 30 broadleaf weeds, including large kochia up to 8 inches tall (as well as ALS-resistant and dicamba-tolerant biotypes), wild buckwheat, lambsquarters, prickly lettuce and sunflowers. It suppresses another 15 weeds, including Russian thistle, pigweed, mustards, field bindweed and pennycress.

Economical rates of 2,4-D or MCPA can be tank mixed for broad-spectrum broadleaf weed control, and CleanWave can be tank-mixed with all leading grass herbicides for one-pass weed and grass control.

Dow AgroSciences is seeking state registrations in Montana, Wyoming and South Dakota for 2006, and plans to add more state registrations in 2007. CleanWave will be targeted in areas of continuous wheat and wheat-fallow systems due to rotational crop restrictions under the label.

Brett Oemichen, product technology specialist, says CleanWave herbicide provided 95% control of kochia and better than 90% control of wild buckwheat in field trials.

“CleanWave has shown excellent crop safety to winter wheat, spring wheat and durum,” Oemichen says. “However, there are a number of rotational crops that are sensitive to residues of aminopyralid. We will recommend the use of CleanWave in areas where continuous wheat or wheat-fallow rotations are common and rotation to dicot crops is a lesser need.”

Growers who use CleanWave herbicide will be able to rotate to a number of crops the following crop year, including barley, canola, flax, mustard, millet, oats, rye, triticale, grain sorghum and corn (field, sweet and pop),  Oemichen adds.

Starane NXTcp gives weed control without rotational restrictions

Starane NXTcp herbicide offers small grains growers complete rotational flexibility. Containing the proven active ingredients fluroxypyr and bromoxynil, Starane NXTcp will be offered as a co-pack in 2006. Dow is pursuing EPA registration of a premix for 2007.

Starane NXTcp provides control of annual broadleaf weeds like kochia, wild buckwheat, lambsquarters and Russian thistle. Broadleaf weed control is enhanced with economical rates of MCPA, 2,4-D or Harmony GT herbicide. It is tank-mix compatible with all leading grass herbicides.

State registrations for Starane NXTcp are being sought in Minnesota, North Dakota, South Dakota, Nebraska, Colorado, Wyoming, Montana, Idaho, Oregon and Washington.
