Studies on phytopathogenic fungus and root – knot nematode on Sesamum indicum

A study has been made to evaluate the effect of Fusarium oxysporum f.sp. sesami and Meloidogyne javanica at varied inoculum levels on sesame (Sesamum indicum) under pot condition. There was corresponding increase in wilt incidence of tested plant in time interval as well as inoculum level. Complete wilting of all lower leaves was recorded after 15 days of inoculation at the highest inoculum (4 g) mycelial mat / pot. Slightly drooping of lower leaves was documented after 30 days of inoculation, when the plant exposed to 2 g mycelial mat / pot. When the plants were inoculated at 2 j2 / g soil caused significant reduction in growth of tested plant. Both the pathogens simultaneously or 10 days prior the other one revealed early expression of wilt symptoms in the treatments where fungus and nematode were inoculated simultaneously (N + F) or nematode was inoculated 10 days prior to fungus.
