Abstract:

the reproductive rates of the root-knot nematodes meloidogyne incognita race 2 and m. javanica in the roots of eight medicinal plant species were assessed under greenhouse condition. each plant, growing in a pot containing 500 ml of sterilized soil, was inoculated with an average number of 5,000 eggs, with five repetitions. egg mass index and reproduction factor data were used for the evaluation, 45-55 days after plant inoculation. achillea millefolium, arctium lappa, bryophyllum calycinum, and crassula portulacea were rated as poor or nonefficient hosts, while plectranthus barbatus and polygonum hidropiperoides were efficient for both nematode species. achyrocline satureoides and tropaeolum majus were efficient for m. javanica, but nonefficient for m. incognita.
