When aldicarb was withdrawn from the U.S. market a couple of years ago, cotton farmers began worrying about how they would deal with root-knot nematodes and other troublesome underground pests without the compound also known as Temik.

Other pesticide formulations were available, but they were expensive and sometimes difficult to apply, which was problematic for cotton producers who were already caught in a cost-price squeeze that had led many to shift acres out of cotton and into corn and soybeans.

Monsanto announced it was introducing a new BollGard 2, Roundup Ready Flex variety bred for resistance to root-knot nematodes at the NPE Summit in Charleston, S.C., Dec. 14.

More than 200 farmers, many of them in the audience at the NPE or New Product Evaluator Summit, tested the new variety in 2013. The new variety, DP 1454NR B2RF, and two other varieties, DP 1410 B2RF, and DP 1441 RF, were introduced as new additions to the Monsanto Deltapine product lineup from the Class of 2014.

 “Our concept in bringing this product to market was to have a competitive yield in non-nematode situations so that growers don’t give up anything in parts of fields where they don’t have nematodes, but when they move into those heavy nematode areas of the field to have a good level of resistance to bring a real benefit or yield advantage,” says Dave Albers, cotton product development manager for Monsanto.
