Respect the Rotation Advocates Need for Immediate Change

Attendees get hands-on with glyphosate weed resistance and innovative technologies.

MARVELL, ARK. (July 20, 2011) — At the University of Arkansas field day held July 19 in Marvell, Ark, guests of Bayer CropScience heard how continual use of a single mode of action contributes to the development of herbicide-resistant weeds that cost growers more money every year in lost yield, time and ultimately farm revenue.

Farmers in Arkansas, Mississippi and western Tennessee are encouraged to combat the spread of pigweed resistant to glyphosate, or Roundup; and to Respect the Rotation™. Palmer pigweed is a large weed that can out-compete the crop, damage farm equipment and ruin fields. In some instances, infestations of resistant pigweed are so severe that farmers have resorted to hand-hoeing or have abandoned their fields.

“Growers have been plowing under fields infested with glyphosate-resistant pigweed,” said Troy Hornbeck, Hornbeck Operations Lead for Bayer CropScience. “If diversity is not part of your weed management program you’re not going to be farming for long.”

As waters recede from this season’s floods, experts expect pigweed seed to spread to more locations and intensify the problem. In addition, recent drought has resulted in reduced efficiency of pre-emergence herbicides, leaving growers to rely solely on a postemergence option. In many cases, that is glyphosate.

Field day attendees heard about innovative solutions for weed resistance management, such as LibertyLink® technology and Ignite® herbicide, as part of a discussion hosted by Bayer’s HBK Seed facility in DeWitt, Ark. “LibertyLink and Ignite offer growers the most reliable option for weed resistance management,” said Andy Hurst, product manager for Bayer CropScience. “This year’s weather conditions have reinforced the need to introduce another mode of action into herbicide programs.”

Participants also heard about Bayer’s investment in seed, germplasm and trait technology while in DeWitt. “We had a great opportunity to share how excited we are with the advances in the soybean pipeline for growers in the Mid-South,” Hurst said.

Hornbeck added, “Bayer is very focused on developing a superior breeding program for growers here to address the Palmer pigweed problem that is tearing through fields.”

Respect the Rotation is an initiative to elevate the importance and grower adoption of herbicide diversity. Rotating crops, herbicide-tolerant traits, and modes of action are essential to improve weed resistance management. The Respect the Rotation Field Tours scheduled for 2011 are bringing the issues to the doorsteps of those who can benefit most from its message.
