Polianthes tuberosa L., known as tuberose, is a bulbous ornamental plant prized for its fragrant flowers. However, tuberose faces significant cultivation challenges due to root-knot nematode (RKN) infestations, particularly by Meloidogyne spp., which cause root galls, nutrient disruption, stunted growth, and reduced flower yield, severely impacting its commercial value. In this instance, a survey was conducted in Tamil Nadu’s tuberose growing districts- Coimbatore, Erode, and Dharmapuri. The study revealed that the widespread root-knot nematode, M. incognita infestations were predominant. Other nematode species such as Helicotylenchus dihystera, Helicotylenchus spp., Pratylenchus spp., Aphelenchus spp., and Filenchus spp. were also identified. These findings highlight the need for effective management strategies to combat rootknot nematode and support the viability of tuberose cultivation in affected regions.
