Abstract: | The root-knot nematode Meloidogyne spp. includes important plant pathogens worldwide. This study has considered nematode Meloidogyne javanica second stage larvae activity in the extracts of Pseudomonas fluorescens strains UTPF5 and cytotoxic effect of the strain on the nematode. The movement of second stage larvae of nematodes in water agar medium at four concentrations of bacterial extracts and second stage larvae mortality rate of hatching nematode and bacterial strains in vitro were affected. Different concentrates of the strain UTPF5 effect nematode larvae movement and disposal of the same. Bacterial extraction kills almost 100% of the larvae hatching after 24?h and a complete ban on egg hatch of biocontrol nematodes and nematode indicated that root-knot nematode larvae movement on the right attract the bacteria P. fluorescens to extract in the first place. |
