The first Pigposium was held in 2010, after one of the worst pigweed years growers have experienced.
“Glyphosate resistance had become an issue for everyone it seemed and growers were desperate for solutions,” says Tom Barber, University of Arkansas weed scientist. “That meeting drew around 800 attendees and as far as I know still holds the unofficial record for the most highly attended meeting conducted by the University of Arkansas Cooperative Extension Service, at least in recent years.”
The second Pigposium was a hands-on field tour in 2014 at the Northeast Research and Extension Center in Keiser, Ark.
“Among other things, that meeting focused on the importance of crop and technology rotation to preserve the remaining tools for pigweed control. The importance of residuals and utilizing multiple effective herbicide modes of action was highlighted in all crops as well as timing and rates of Liberty applications. We also talked about new technologies and alternative methods for pigweed control such as ‘zero tolerance’, cereal rye cover crops and narrow-windrow burning.
