Glyphosate Resistance Issue Gets Attention At 2009 Beltwide Cotton Conferences

Weeds resistant to glyphosate now in seven Southeastern states.

Glyphosate-resistant weed issues have been making headlines in the Carolina-Virginia region for a couple of years, now. To judge from interest at this year's Beltwide Cotton Conferences in San Antonio, Jan. 5-8, those issues are just as important for cotton producing states in much of the rest of the country.

Weed specialist Stanley Culpepper of the University of Georgia addressed the growing problem during the opening morning session, Tues., Jan. 6, by noting this resistant weed has now spread to seven states in the Southeast.

"Resistance is key and most importantly, the glyphosate resistance that many of our growers are facing," Culpepper told the Beltwide audience of several hundred. "Herbicide resistance and the weed issues we are facing are extremely challenging to address and manage."

Culpepper urged growers and others to attend several Beltwide presentations on glyphosate resistance, including a grower roundtable on Wednesday. At least 10 papers were to be presented during Beltwide's Cotton Weed Science Research Conference, he said.

Pointing out that some growers may be in denial of the problem, he said, "Accepting the seriousness of the situation is key. Growers need to overcome the belief, 'It won't happen to me. Prevention and early detection are essential."
