Abstract: A pot experiment was carried out during the rabi season of 2015-2016 to study the interaction of Meloidogyne incognita and Colletotrichum lagenarium on ivy gourd. Experimental study revealed that, the dual inoculation treatments significantly decreased plant growth parameters were the treatment with M. incognita@ 1000J2 kg-1 of soil and C. lagenarium @ 2% (w/w). The treatment with M. incognita @ 1000J2 kg-1 of soil + C. lagenarium @ 2% (w/w) simultaneous inoculation was statistically superior in decreasing the plant growth parameters of ivy gourd. The number of galls, eggmasses and final nematode population were maximum in the treatment with M. incognita @ 1000 J2 per kg of soil. The maximum disease incidence was observed in the treatments with M. incognita @ 1000J2 kg-1 of soil + C. lagenarium @ 2% (w/w) after 15 days of inoculation and simultaneous inoculation of M. incognita @ 1000J2 kg-1 of soil + C. lagenarium @ 2% (w/w).
