The Georgia Cotton Commission and University of Georgia (UGA) Extension Cotton Team remind growers about the benefits of implementing nematode-resistant varieties for the 2024 season.
Bob Kemerait, UGA Extension plant pathologist, talked with AgNet Media's Randall Weiseman about the benefits of using resistant varieties at the commission's annual meeting in January.
Nematodes are microscopic worms that can devastate cotton and other row crops. Root-knot nematodes can be the most problematic because of their wide host range. They feed on cotton roots and cause swelling, or "galls," to develop. The galls disrupt the function of the roots, which stunts the plant's growth. Further, female nematodes feed and lay eggs at the galls.
Kemerait also addressed the yield concerns growers have if they are planning to utilize these resistant varieties.
