Biological management of meloidogyne incognita using entomopathogenic bacterial cell suspensions with other bioproducts in egg plant

In vitro assessment was performed with bacterial cell suspensions of xenorhabdus spp. and photorhabdus spp. with bio-products (abamectin,emamectin and azadirachtin) against meloidogyne incognita kofoid & white (chitwood) on egg plants (solanum melongena l.). bacteria were isolated from steinernema asiaticum and heterohabditis bacteriophora,respectively. maximum control (63.6%) for number of females was observed in combined treatment of xenorhabdus spp. + abamectin,60.7% in the case of photorhabdus spp. + abamectin treatment,and 57% in abamectin treatment. the minimum control (45%) was observed in azadirechtin treatment as compared to control. in case of reproduction factor,photorhabdus spp. + abamectin treatment proved the most effective against m. incognita,whereas azadirachtin and emmamectin treatments were the least effective. the results clearly showed synergistic effect of bacterial cell suspensions and abamectin in controlling m. incognita population.
