| Abstract: | Crop loss caused by the root-knot nematode Infesting Coleus parvlflorus and its control was studied in a pot culture experiment and a field experiment in the Department of Entomology, College of Agriculture, Vellayani, Trivandrum, during August to December, 1986. The number of leaves, shoot length, fresh shoot weight and weight of tubers obtained were less in inoculated plants than in control. The yield and growth parameters showed a negative correlation with the population of nematodes. A high positive correlation was noticed between tho tuber weight and the number of leaves and shoot weight of coleus. The shoot length did not influence the tuber yield significantly |
