Surveys were conducted of coriander plantations from open and protected cultivations at Karnataka for the
prevalence of nematode. Heavy infestation of root-knot nematode was observed on coriander with small to big sized
galls or knots on the roots. Soil and root samples were collected for analysis of nematode infestation. Coriander
plants also exhibited poor growth showing stunting and chlorosis due to severe infestation. This is the first report of
root-knot nematode from Karnataka.
