Valent Canada adds Valtera Herbicide to 2009 product lineup

Brand new active ingredient benefits soybean growers

February 5, 2009

GUELPH, ON (Feb. 5, 2009)—Valent Canada has received Health Canada’s Pest Management Regulatory Agency approval to register Valtera Herbicide for use in soybeans. Valtera is a low use rate preemergence herbicide which gives growers residual control of many broadleaf weeds and enhanced post emergence weed control when tank mixed with glyphosate. It has been sold in the U.S. since 2001 under the trade name Valor® Herbicide.

Valtera controls annual nightshade species (Eastern black nightshade and hairy nightshade), pigweeds (redroot and green), common ragweed, common lambsquarters, and dandelion. Valtera also provides suppression of green foxtail.

New active ingredient
Valtera contains the active ingredient flumioxazin, a member of the protox inhibitor type of herbicides (Group 14), and offers new management options for weeds resistant to Group 2 & 5 herbicides. However, unlike many other Group 14 herbicides, flumioxazin provides enhanced burndown and residual control.

Flumioxazin works by inhibiting production of an enzyme important in the synthesis of chlorophyll. "Its rapid soil and water dissipation," said Regina Rieckenberg, Valent Canada sales and marketing manager, "along with a low use rate, results in a low carryover potential to rotational crops."

In identity preserved soybeans, Valtera is intended to be used in a program with other residual herbicides. It should be applied as a preplant or early preemergence herbicide, from 30 days prior to planting and up to three days after planting (before emergence). In burndown situations, it can be used as a foundation herbicide partner with glyphosate in glyphosate-tolerant soybeans.

"By using flumioxazin in a program with other herbicides," said Rieckenberg, "the grower helps to preserve the effectiveness of other herbicides and decreases or delays development of weed resistance. With excellent weed control and flexible rotational restrictions, Valtera ushers in a new era of weed control."

Valtera is one of the many quality products from Valent Canada, including plant growth regulators, herbicides and insecticides.
