Abstract: An investigation was carried out for two consecutive years, 2016 and 2017, to test the efficacy of different pre sowing nursery treatments with two fumigants viz., dazomet (@ 40g/ m²) and metham sodium (@ 14ml/ m²), one organic formulation i.e., jeevamrit (@ 10%), and two bioagents viz., Trichoderma viride (@ 50g/ m²) and Pseudomonas flourescens (@ 50g/ m²), along with untreated control, against root knot nematodes (Meloidogyne incognita) infesting tomato nursery. The results revealed that maximum percent germination and shoot lengths were of jeevamrit, dazomet and metham sodium followed by T. viride and P. flourescens treated seedlings, all being better than control. In reference to nematode soil populations and root gall index, dazomet and metham sodium had better efficacy in comparison to T. viride, P. flourescens, jeevamrit and control. There was no significant difference in nematode soil population between jeevamrit and control.
