About five years ago, glyphosate-resistant Palmer amaranth showed up in northeast Arkansas, after a long crusade against resistant horseweed. State Weed Specialist Ken Smith, now retired, urged growers to join forces to eradicate every visible weed. Clay County Extension Agent Andy Vangilder continues to carry the torch.
“A few growers took the initiative and set the example,” he says. “This kind of control is all about attitude. If one guy wants to go spray a ditch or another guy’s edge of a field, he’s going to save everyone trouble next year. Someone has to suggest it and encourage others; it could be you,” he tells farmers.
