Pigposium to feature weed control experts at NEREC
July 15, 2014
- Respect the Rotation Pigposium Field Day set for Wednesday, July 23
- Soybean, corn and cotton to be discussed
KEISER, Ark. – Control of resistant weeds is a moving target and crop producers need every advantage they can get to stay ahead of the issue, said Tom Barber, extension weed scientist for the University of Arkansas System Division of Agriculture.
Next Wednesday, July 23, weed experts will provide corn, soybean and cotton growers with the latest tools to use in their ongoing fight.
The “Respect the Rotation Pigposium Field Day” runs 8 a.m. to 1 p.m., including field tours and lunch at the Northeast Research and Extension Center in Keiser. The event is sponsored by The University of Arkansas System Division of Agriculture and Bayer CropScience. Participants may register at www.bayerrespecttherotation.com. Tours will leave for the fields at 9 a.m.
The Pigposium series was begun when herbicide resistant pigweed began to pop up in cotton and other fields in the Mid-south.
“At the first Pigposium, everyone was in shock of the problem that we were all about to face or were facing with pigweed,” said Bob Scott, extension weed scientist for the University of Arkansas System Division of Agriculture. “The purpose of this meeting is to talk about current control options refining those options and discuss things that are coming in the future you won't want to be left out of the new technology when it gets here.”
Barber said Arkansas growers have been gaining ground on the problem of glyphosate-resistant pigweed in the last couple of years.
“New technologies, Zero Tolerance mentality and diverse crop rotations have enabled producers to use multiple herbicide modes of action and rotate chemistries to improve pigweed management and prevent further resistance in pigweed populations,” he said. “Growers need the most up-to-date recommendations to maintain control and diligence in regard to future management of pigweed populations and herbicide resistance in general. Growers should attend to gain a better understanding of new technologies and their fit in the fight against weed resistance and pigweed.”
The agenda includes:
- Residual herbicide programs in Balance GT - Bob Scott, extension weed scientist for the University of Arkansas System Division of Agriculture.
- Best management practices for high yield soybean production and managing resistant weeds. - Chuck Farr, consultant; and Stephen Wyatt, soybean producer
- Multiple herbicide weed resistance and using effective modes of action - Aaron Hager,University of Illinois professor of weed science
- Herbicide programs for use in soybean systems utilizing future technologies - Jason Norsworthy, professor-weed science for the University of Arkansas System Division of Agriculture.
- Weed control programs in GlyTol LibertyLink cotton - Tom Barber, extension weed scientist for the University of Arkansas System Division of Agriculture.
- Herbicide programs in corn with am emphasis on resistance management - Larry Steckel, University of Tennessee extension weed specialist.
The event includes lunch and a wrap-up by Fred Bourland, director of research station and Norsworthy.
