CHERRY VALLEY, Ark. – Herbicide-resistant Palmer amaranth, commonly known as pigweed, can be a costly problem for farmers. As the weed becomes increasingly unfazed by available chemistries, some growers may find that reuniting with an older approach may be the new tool they’ve been seeking.
Researchers and agronomists with the University of Arkansas System Division of Agriculture are now researching the efficacy of using alfalfa cover crops to slow or defeat the seemingly-unstoppable weed.
On Friday, Aug. 23, John Jennings, extension forage specialist for the Division of Agriculture and the primary investigator for this research, and others will offer a field day to discuss their findings.
“There is no pigweed that can stand up to being mowed every 30 days, when alfalfa hay is harvested,” Jennings said.
Discussion topics include pigweed biology and control, economics and alfalfa planting and management. All interested crop and livestock producers are encouraged to attend one or both field days.
To register and help with meal planning, please call Linda McCargo at 501-671-2171. There is no cost to attend.
