Fungi Associated With Sugar Beet Cyst Nematode (Heterodera schachtii) From Fields of West Azarbaijan Province, Iran (II)

In order to identify the fungi associated with sugar beet cyst nematode, Heterodera schachtii, in W. Azarbaijan province, northwest Iran, a number of 400 fungi isolates were recovered and studied from different stages of the nematode life cycle during 2002-2004. In this paper, 12 identified species belonging to 11 genera are presented as Alternaria alternate, Alternaria malorum, Arthrinium phaeospermum, Arthrobotrys oligospora, Botryotrichum piluliferum, Chaetomium spiralotrichum, Cladosporium oxysporum, Cylindrocarpon destructans, Embellisia chlamydospora, Geomyces pannorum, Stemphylium botryosum and Ulocladium atrum. Among them, two species viz. Botryotrichum piluliferum and Geomyces pannorum are as new records for the mycoflora of Iran. Four species viz. Alternaria malorum, Arthrinium phaeospermum, Botryotrichum piluliferum and Geomyces pannorum are reported from naturally infected sugar beet cyst nematodes for the first time. With dentification of these fungi, they will be considered as biological control candidates of sugar beet cyst nematode.
