Abstract
Damaging threshold levels of root-knot nematode Meloidogyne incognita and root-rot fungus Fusarium solani on plant growth parameters, viz., plant length, fresh and dry weight of chilli were determined by conducting their pathogenicity trials in pot experiments. The results revealed a significant reduction in the plant growth parameters at and above the inoculum level of about 1000 J2 per plant of M. incognita and the highest reduction was recorded at 8000 J2 per plant. Significant reduction in plant growth parameters was recorded at 1.00 g mycelial mat of F. solani per plant, while the highest reduction was observed at 8.00 g mycelial mat per plant. The damaging threshold level was 1000 J2 per plant of M. incognita and 1.00 g mycelial mat of F. solani.
