Nematode Management Begins with Variety Selection
Nematode pressure exists in a range of soil types across the Cotton Belt and can adversely affect yield potential. Deltapine® brand nematode-resistant cotton varieties can suppress nematode populations from increasing in the soil, leading to a major difference in plant health and yield potential.
“Each of these varieties has demonstrated very stable yield potential when planted in soils with and without nematode pressure and were proven to perform in the New Product Evaluator (NPE) program,” said Eric Best, Deltapine cotton product manager. “Cotton growers looking for outstanding yield potential with protection against nematodes have strong options in the Deltapine product lineup, including in the Bollgard 3® ThryvOn® cotton with XtendFlex® Technology platform.”
ThryvOn® Technology for cotton provides built-in protection against key tarnished plant bugs and thrips species and can be a game changer for growers. With fewer thrips feeding on the young plants, cotton crops can emerge healthier and often reach pinhead square faster.*
ThryvOn Technology for cotton also helps suppress plant bugs, potentially delaying threshold buildup and reducing the number of sprays needed. With a 6.1% increase in square retention, ThryvOn Technology helps plants reach their yield potential.**
Cotton Varieties for Nematode Resistance
DP 2436NR B3TXF is a mid-maturity Bollgard 3 ThryvOn cotton with XtendFlex Technology variety with resistance to root-knot nematodes and bacterial blight, demonstrating strong performance in West Texas. This variety has moderate tolerance to Verticillium wilt and is a good fit in the Central and Southern Texas High Plains.
DP 2522NR B3TXF is an early- to mid-maturity variety offering resistance to both reniform nematodes and bacterial blight. In 2024 NPE plots, this Class of ’25 variety demonstrated stable yield performance potential on reniform nematode-infested fields across its targeted markets of the Coastal Bend of South Texas, the lower Mid-South and the pest Southeast.
DP 2349NR B3XF is a Bollgard 3 XtendFlex cotton variety with resistance to southern root-knot nematodes and bacterial blight that demonstrated strong performance in the Southeast and Mid-South.
DP 2141NR B3XF is a Bollgard 3 XtendFlex cotton variety with resistance to both reniform and southern root-knot nematodes. This variety has demonstrated outstanding yield potential for the Southeast and Mid-South.
DP 2143NR B3XF is a Bollgard 3 XtendFlex cotton variety for the Southwest with resistance to both reniform and southern root-knot nematodes and moderate tolerance to Verticillium wilt.

No dicamba may be used in-crop with seed with Roundup Ready® Xtend Technology, unless and until approved or specifically permitted, and no dicamba formulations are currently registered for such use in the 2025 season. Please follow www.roundupreadyxtend.com/pages/xtendimax-updates.aspx for status updates. Dicamba may harm crops that are not tolerant to dicamba. Performance may vary, from location to location and from year to year, as local growing, soil and environmental conditions may vary. Growers should evaluate data from multiple locations and years whenever possible and should consider the impacts of these conditions on their growing environment. The recommendations in this material are based upon trial observations and feedback received from a limited number of growers and growing environments. These recommendations should be considered as one reference point and should not be substituted for the professional opinion of agronomists, entomologists or other relevant experts evaluating specific conditions. Trials compare germplasm performance; input and trial management decisions determined by grower establishing the applicable trial.
