Characterisation of Pythium capillosum– A new pathogen of Xiphinema pachtaicum (Nematoda: Longidoridae)

Abstract Isolation on culture media followed with macroscopic, microscopic, molecular and phylogenetic analyses and pathogenicity test allowed us to identified Pythium capilosum found to be capable of destroying certain dagger nematode through endozoic parasitism from ingested oomycete zoospores. Although endoparasitism of free-living nematodes is found to be common among Oomycetes in nature, this is the first finding of such occurrence in Bosnia and Herzegovina soils. The obtained results could give rise to initiate a study for the new biological approach for nematode control promoting environmentally safe and sustainable control measures.
