The present study makes an attempt to identify the plant parasitic nematode associated with chrysanthemum in Karnataka. The primary data was collected using random sampling technique Bagalkote, Gadag, Dharwad and Belgum comprising total nine villages were selected for study during the year 2012-2014. The findings reveals that, the plant parasite nematode were found to be eight species, viz., Meloidogyne, Helicotylenchus, Tylenchulus, Xiphinema, Pratylenhus, Hemicyclophora, Hoplolaimus and Radopholus which were commonly found in the roots of commercially cultivated chrysanthemum flower crops. Further, the study also identified, in Belgaum district at 13 different location Pratylenchus and Meloidogyne sp. occurred more frequently with 60 to 100 per cent absolute frequency. Similarly, in case of Dharwad district, Pratylenchus, Helicotylenchus, Meloidogyne and Tylenchus sp. were more frequent with 100 per cent distribution and abundant. In addition, in case of Gadag district, Pratylenchus had the 100 per cent frequency with highest absolute density (110). However, whereas in Bagalkote district, Meloidogyne revealed highest frequency distribution (100 %) and absolute density (300) when compared to other districts during the study period. Hence the study suggests that suitable plant protection measures need to be adopted for the appropriate nematode species control in these areas and also areas and also areas which have similarly agroclimatic features.
