In late 2010, herbicide-resistant pigweed had such a grip on Mid-South fields that University of Arkansas researchers held a conference addressing only that weed. Cleverly titled “Pigposium” the event drew an impressive 800 attendees.

Now, four years later and still seeking to solve the pigweed problem, a revamped Pigposium is back. Set for July 23, the “Respect the Rotation Pigposium” -- co-sponsored by the University of Arkansas and Bayer CropScience – will kick off at 8:30 a.m. at the Northeast Research and Extension Center in Keiser, Ark.

In early July, Delta Farm Press caught up with Bob Scott, Arkansas weed specialist, to discuss the conference and field tour. Among his comments:

On the necessity for such events…

“When we had the first Pigposium, the resistant pigweed problem had really just exploded. We had a great turnout at that meeting because it was a problem for producers that they’d not faced before. They came looking for answers.

“At this point, four or five years later, most growers know they have resistant pigweeds and are doing what they can to deal with it. The problem, of course, is everything we try on pigweeds is coming up short.

“We’re utilizing LibertyLink soybeans, residual herbicides in Roundup Ready beans. But it isn’t enough. We’re barely keeping ahead of these pigweeds in soybean fields. The same is true in cotton fields.

“So, we’re just surviving. There’s no beating pigweed at this time. 

“This meeting is looking at the next steps we might take, new technologies. There are also small things we can do, things to tweak, with the existing technologies. There’s always room for improvement.

“But I think eyes at the meeting will really be on the new tools that are coming soon. We just have to wait for them to get through the long process of getting to market.”
