R. Duponnois, C. Netscher, T. Mateille

Abstract


The effect of the rhizosphere microflora associated with spores of Pasteuria penetrans on the attachment of the spores on juveniles of Meloidogyne graminicola has been studied. The microflora stimulated the attachment of the spores on the juveniles and consequently reduced the invasion of the roots of tomato plants y the nematodes. The role of a helper rhizosphere microflora for biocontrol of root-knot nematodes by P. penetrans is suggested.
