A pathogenicity test was conducted against root-knot nematode, Meloidogyne incognita
and root rot fungus, Rhizoctonia solani on okra (Abelmoschus esculentus). The results
showed that with the increase in the inoculum of M. incognita i.e. from 250-8000
J2/plant and R. solani from 0.25 – 8.0 g mycelial mat/plant caused reduction in plant
growth parameters viz., length, fresh weight and dry weight. The highest reduction in
plant growth parameters was recorded in the plants inoculated with the 8000 J2/kg of M.
incognita and 8.0 g mycelial mat of R. solani/plant of fungus whereas the least reduction
was recorded in 250 J2/plant of nematode and 0.25g mycelial mat/plant. However the
significant reduction in plant growth parameters was recorded in the plants inoculated
with at and above 2000J2/kg and 2g mycelial mat/plant of nematode (M. incognita) and
fungus (R. solani) respectively. So these levels were pathogenic level.
