Agronomist and weed specialist weigh in on potential return of divisive weed killer  

Stanley Culpepper, an agronomist with UGA’s Cooperative Extension, and Mark Czarnota, an associate professor of horticulture in the College of Agricultural and Environmental Sciences, spoke with The Atlanta Journal-Constitution about the debate around a weed killer called dicamba.  

Certain uses of the herbicide were barred by a federal court last year, though the EPA may allow farmers to use it again. Culpepper is in favor of reauthorizing dicamba products. 

“If our farmers don’t have a way to control the pest, they can’t provide us (animal) feed, food and fiber,” Culpepper said. 

However, Czarnota raised concerns about dicamba-laden runoff getting into water supplies and harming other crops, such as blueberries. 

“The product just worries me,” he said. “It’s one of those that keeps you up at night.”
