Abstract
An extensive survey of about 50 ornamental plants growing in A.M.U. campus were carried out to find out the infection of root-knot ( Meloidogyne spp.) and reniform nematodes ( Rotylenchulus reniformis ). Out of 50 species of ornamental plants studied, 29 species of these plants were found to be infected with root-knot nematodes ( Meloidogyne spp.) and 15 species were infected with reniform nematode ( Rotylenchulus reniformis ). The highest percentage of infection of root-knot nematodes was observed in Impatiens balsamina (100%) and reniform nematode was observed in Hibiscus rosa-sinensis (56%). Among the Meloidogyne spp. the highest percentage of infection of M. incognita was observed in Pseuderanthemum atropurpureum (80%) whereas, the highest percentage of infection of M . javanica and M . arenaria was observed in Mirabilis jalapa (72%) and Celosis cristata (28%).
