Particular Microbial Attachment to Root Knot Nematodes in Suppressive SoilMohamed Adam,a,b Andreas Westphal,a Johannes Hallmann,a Holger HeueraJulius K n Institut ederal Analysis Centre for Cultivated Plants, Braunschweig, Germanya; Department of Zoology and Nematology, Faculty of Agriculture, Cairo University, Cairo, EgyptbUnderstanding the interactions of plant-parasitic nematodes with antagonistic soil microbes could provide opportunities for novel crop protection techniques. Three arable soils have been investigated for their suppressiveness against the root knot nematode Meloidogyne hapla. For all three soils, M. hapla created drastically fewer galls, egg masses, and eggs on tomato plants in unsterilized than in sterilized infested soil. Egg numbers had been reduced by up to 93 . This recommended suppression by soil microbial communities. The soils drastically differed inside the composition of microbial communities and in.
