Abstract
ABSTRACT Plant‐parasitic nematodes pose a major constraint in fruit tree nurseries, adversely affecting the health and vigor of seedlings. The present study was undertaken to assess the community structure of plant‐parasitic nematodes associated with tropical and subtropical fruit tree nursery crops in the north‐western Himalayan state of India, Himachal Pradesh. A total of 280 soil and root samples were collected during 2023–2024 from 20 commercial nurseries located in six districts. The analysis revealed the presence of nine plant‐parasitic nematode taxa, with the following relative abundances: Meloidogyne spp. (51.29%), Helicotylenchus spp. (23.83%), Hoplolaimus spp. (7.52%), Tylenchorhynchus spp. (7.08%), Mesocriconema spp. (6.95%), Pratylenchus spp. (2.23%), Tylenchulus semipenetrans (0.86%), Xiphinema spp. (0.17%) and Tylenchus spp. (0.01%). Interestingly, no visible above‐ground symptoms were observed in the sampled plants, except for citrus seedlings infested with T. semipenetrans , which showed stunted growth, chlorotic leaves and dieback symptoms. These findings offer baseline information on the assemblage and distribution of plant‐parasitic nematodes in fruit nurseries of this region and underscore the need for further investigation and the development of effective nematode management strategies.
