Abstract
The nematicidal properties of eight isolates of rhizobacteria as well as an
isolate of Pseudomons fluorescens against egg hatching and juveniles mortality of
Meloidogyne incognita after different exposure periods were investigated in vitro.
Results indicated that all tested bacteria caused significant effects on M. incognita
with different percentages of egg hatching inhibition and juveniles mortality. Out of
bacterial isolates, 2KT (54.0%), 3SN (49.2%) and Pseudomonas fluorescens
(46.4%) significantly induced the greatest egg hatching inhibition of M. incognita.
Moreover, the longer the exposure to bacterial isolates the higher the juvenile
mortality was revealed. The bacterial isolates 2KT and 3SN that exhibited
pronounced nematicidal activity against M. incognita were identified as Bacillus
subtilis and P.aeuroginosa, respectively.
