Combination of tactics important to control nematodes

In Southeast Farm Press

Both Clemson University and North Carolina State University are issuing warning bells for nematodes in the Carolinas.

The nematode issue was front in center at both Clemson’s corn and soybean production meeting in Dillon, S.C., Feb. 8 and at N.C. State’s Road Show production meeting the following day in Plymouth, N.C. A concern in both states is the Southern root knot nematode and the soybean cyst nematode.

Both John Mueller, Clemson Extension plant pathologist and director of the Edisto Research and Education Center, and Lindsey Thiessen, N.C. State Extension entomology and plant pathology specialist, said variety selection is job one for nematode control. Both specialists encouraged farmers to turn to soybean varieties that offer nematode resistance.

“We need to do a really good job of choosing varieties, and you need to identify the highest probability problems that you have, whether it’s a fungal disease or a nematode,” said Mueller at the Clemson meeting. “For soybeans, you need to find the variety that is resistant to the nematode species that you think you have such as root knot nematode resistant or soybean cyst nematode to be successful.”

N.C. State’s Thiessen echoed Mueller’s advice, emphasizing host resistance as the best defense against soybean cyst nematode because it is the cheapest thing farmers can do. “Pick a variety that has resistance to soybean cyst,” she said at the Plymouth meeting.
