Cotton farmers went back to some old practices, pre-emergent herbicides, to take care of resistant weeds. “We used some old technology and began re-educating ourselves on how to use older herbicides along with new technology. That’s where we are now.”

Osborne said farmers still “have what we need. And we will have other options in the near future.” He said cotton varieties resistant to Dicamba and 2,4-D will be available as soon as 2015. “That offers a huge opportunity. We expect a lot of interest.”

 

 

But new technology also requires more education, he said. “We have new solutions to resistance issues but we also will have a new marriage between education and new technology. We learned from Roundup Ready cotton about the potential for drift, so we know what’s in store.”

He said the new technology will pose challenges. “But we can be safe and effective with proper management.”

He said the new Dicamba and 2, 4-D resistant varieties will have requirements “we have not seen before. New restrictions will include buffer zones to protect non-resistant cotton and other vulnerable crops from potential drift. Nozzle types also will change, Osborne said.

“Droplet size is a big deal. Controlling droplet size will mitigate a large part of the drift issue. Recommendations are in place and should prevent some of the issues we had early with Roundup Ready technology. Again, the combination of technology and education will make us successful.”
