Abstract

To examine the influence of different preparations from the body of earthworm Lampito mauritii on selected soil borne bacterial pathogens. The experiments were based on the principle of agar diffusion, minimum inhibitory concentration  and rate of germination. This experiment involved the recording of inhibition zones formed by various extracts amount of turbidity and suppression of rate of germination by different extracts. Colonic fluid, body wall and gut extracts were found to be inhibitory to Xanthomonas campestris, Ralstonia solanacearum, Erwinia cartovora. The mixed extract when tested on this pathogen has shown a strong clear inhibition zone. The study has proved that earthworm extracts can be effectively used for suppression of soil borne pathogens and that it can be evolve as potential biopesticide.
