Abstract: Currently management of the reniform nematode Rotylenchulus reniformis is limited to crop rotations and nematicides. Selected cotton varieties were screened for resistance in the greenhouse and for tolerance in field locations. Field locations included two conventionally tilled, monocultured cotton fields (ES and LM) and one no-till field following a year of corn production (LA). Greenhouse trials indicated that all commercial cotton varieties tested were susceptible to the reniform nematode. Sixty days after initial inoculation of 2000 vermiform nematodes, reproductive indexes ranged from 13 to 70 on Sure Grow 747 and Deltapine 424 BGII/RR, respectively. In the ES field, Stoneville 4793 RR produced 393 kg/ha more Seed cotton per ha without a nematicide as compared to the nematicide treated plots. Seed cotton yields were not (P < 0.05) increased by the application of a nematicide for Fiber Max 991 RR and Fiber Max 991 BR. The yields for the remaining 29 varieties (P < 0.05) were increased in the nematicide treated plots as compared to the non treated plots. In the LM field, all varieties treated with the nematicide out yielded (P < 0.05) varieties without the nematicide. Following one year of corn production in the LA field, nematicides had no impact on yield for any variety.
