Abstract:
Taking rhizosphere soil and roots of disease-resistant tomatoes as isolation objects，using dilution method,biocontrol bacterial against root-knot nematode were screened and identified.The results showed that 47 isolates were got among which 40 were from rhizosphere soil and 7 were from roots.Strains W49 and W21 showed nematicidal activity and egg hatching inhibition rate against Meloidogyne incogonita were over 90.0% and 96.0%,which were identified as Bacillus simplex and Bacillus endophyticus based on cultural and morphological characteristic and 16S rDNA sequencing analysis.
