Abstract


Pink and white periwinkles were examined in pot experiments as trap plants for root-knot nematodes (Meloidogyne incognita and M. javanica). Pots were inoculated with 2000 eggs or second stage juveniles per plant and after three months were replaced with the susceptible okra to judge the extent of nematode suppression or trapping. There was 100 per cent reduction of root-knot nematodes on okra after pink periwinkle and 95 per cent after white periwinkle treatments, thus, indicating their value as trap crop.
