Pasteuria spore attachment to root-knot juveniles reduced significantly as dilution factor of bacterial suspension increased. Isolate UK 1 provided maximum spore attachment to Meloidogyne javanica juveniles in all 3 dilutions of bacterial spore suspension (S, S/2 and S/4) compared to other test isolates and the control. Infected juveniles by spores of all bacterial isolates (UK 1, PK 1 and PK 2) significantly suppressed invasion to tomato roots. There was a significant difference in root invasion by nematodes exposed to the different concentrations of test bacterial isolates.
