- Biocontrol of the nematode Meloidogyne javanica was studied using the Argentinean strains Pseudomonas fluorescens MME3, TAE4, TAR5 and ZME4 and Bacillus sp. B7S, B9T and B19S. Pseudomonas protegens CHA0 was used as a positive control. Egg hatching and juvenile mortality were evaluated in vitro by exposure of nematodes to bacterial suspensions or their cell-free supernatants (CFS). The effect of bacteria on nematode infestation of lettuce was also studied. results showed that most of the tested strains and CFS reduced egg hatching and juvenile survival in vitro. The bacterial suspension of Bacillus sp. B9T produced the lowest hatching of eggs. Juvenile mortality was higher when M. javanica was exposed to Bacillus sp. than to Pseudomonas spp. suspensions. Except for CFS of B9T, all filtrates inhibited hatching at levels similar to or higher than the biocontrol strain P. protegens CHA0. The CFS of CHA0 showed the highest level of juvenile mortality followed by Bacillus sp. strains and P. fluorescens TAE4. None of the inoculated rhizobacteria reverted the negative effect of infestation on the aerial dry weight of lettuce plants. However, inoculation impacted on reproduction of M. javanica by reducing the development of galls and egg masses on roots and diminishing the number of individuals both on roots and in the substrate, as well as the reproduction factor. These results show that most of the analyzed native strains can control the nematode M. javanica. Among them, P. fluorescens TAE4 and Bacillus sp. B9T showed the most promising performances for the biocontrol of this pathogen and have a potential use in the formulation of commercial products.
