Determination of Plant Parasitic Nematodes on Oil Rose Growing Areas in Isparta Province of Türkiye

Abstract

The study was carried out to investigate plant parasitic nematodes in oil rose growing areas in Isparta province in July-August 2022. Soil samples were taken from 15 different areas and the study was carried out with 65 samples. A total of 12 species of plant parasitic nematodes were determined in the study. These are Tylenchus spp., Aphelenchus spp., Pratylenchus spp., Dictylenchus spp., Dorylaimus spp., Paratylenchus spp., Longidorus spp., Xiphinema spp., Meloidogyne spp., Helicotylenchus spp. and Merlinus spp. The Pratylenchus (52.3%), Paratylenchus (38.5%) and Helicotylenchus (41.5%) seemed to be the most prevailing genera. The least common genus is Meloidogyne (7.6%). Root knot nematode species molecular identification was determined by species-specific primers from larvae. The 5 samples taken from cultivated oil rose fields were found to be infected and were detected with Meloidogyne hapla Chitwood, 1949. Densities of M. hapla varied between 60-480/100 g soil. This is the first report identification of M. hapla on oil rose in Türkiye.
