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 of soil and C. lagenarium @ 2% (w/w). The treatment with M. incognita @ 1000J2/kg 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/kg of soil. The maximum disease incidence was observed in the treatments with M. incognita @ 1000J2/kg of soil + C. lagenarium @ 2% (w/w) after 15 days of inoculation and simultaneous inoculation of M. incognita @ 1000J2/kg of soil + C. lagenarium @ 2% (w/w).
