Ten varieties of Tagetes were tested in 20 cm pots against root-knot incidence. An initial population of 3000 larvae/pot resulted in lowest number of galls formed on var. White Alaska followed by chrysanthemum apetatus of T. erecta. In general, inoculated plants of both T. erecta and T. patula showed an increase in shoot length as compared to uninoculated check treatments. In spite of heavy to moderate nematode infestation, no reduction in shoot length was recorded amongst the varieties tested.
