Management of this pest in cotton fields only gives partial control and is sometimes neither economical nor profitable. Past research has shown no resistance to the reniform nematode in currently available commercial cotton cultivars. Screenings of several currently available cotton cultivars for tolerance to the reniform nematode were conducted in the growing seasons of 2006 and 2007 at the Delta Branch Experiment Station in Stoneville MS. Several cultivars were identified as tolerant and productive including 'Croplan Genetics 3520 B2RF, ' 'DynaGrow 2520 B2RF, ' and 'Stoneville 5242 BR.' Other cultivars were tolerant but less productive, including 'Deltapine 488 BG/RR, ' 'Fibermax 960 B2R, ' and 'Stoneville 5599 BR.' 'Deltapine 455 BG/RR, ' 'Phytogen 370,' and 'Phytogen 485' were shown to be productive, but not tolerant to the reniform nematode.
