Cotton Variety Evaluation with and Without Velum for Root-Knot Nematode Management in Central Alabama, 2024
Root-knot nematode ( Meloidogyne incognita) is a major pathogen of cotton, causing root galling, stunted growth, and yield losses. This study evaluated the efficacy of nematicides and resistant cotton varieties in managing root-knot nematode infestations. Field trials were conducted at Auburn University's Plant Breeding Unit, Tallassee, AL, in 2024, using four cotton ( Gossypium hirsutum) varieties: DP 2038 B3XF, DP 2131 B3TXF, DP 2143NR B3XF, and DP 2349NR B3XF. Nematicide treatments included Velum (in-furrow), Copeo (seed treatment), a combination of both, and an untreated control. Results showed that integrating resistant varieties and nematicides improved root-knot nematode management and cotton productivity, highlighting the potential benefits of combining these strategies for sustainable nematode control.
