Studies on the disease complex incidence by Meloidogyne incognita and Fusarium solani on Poi,Basella rubra

A survey of Poi crop in Ghaziabad (UP) exhibited a disease complex incidence by Meloidogyne incognita and Fusarium solani causing synergistic effect on the host. Paecilomyces lilacinus was found from the egg masses of M. incognita and Aspergillus niger and Aspergillus terreus from the rhizosphere of root-knot infected Poi crop. Paecilomyces lilacinus parasitised the eggs to a greater extent. The level of parasitism was highest (65%) by P. lilacinus while Aspergillus spp. did not colonise the eggs. Fusarium solani which in the present investigation has been established to be pathogenic to Poi plant.
