Plant parasitic nematodes are responsible for huge crop losses worldwide. Certain Meloidogyne species are particularly damaging to horticultural crops in southern Europe. To reduce these losses, a variety of methods have been employed namely crop rotation, resistant varieties and the use of nematicides. In order to obtain alternatives to the use of certain nematicides such as methyl bromide, a very efficient but ozonedepleting fumigant to be banned within the European Union in 2010 in accordance with the Montreal Agreement, biological control agents with potential efficacy may be used. The facultative parasite Verticillium chlamidosporium, present in the soil, has proven to be a potential antagonist against nematodes by parasitizing the exposed egg masses produced by Meloidogyne females. Preliminary results include the identification of V. chlamydosporium isolates in Portugal, as part of an ongoing European research project
