Fungi Associated with Cysts of Globodera rostochiensis, Heterodera cruciferae and Heterodera schachii (Nematoda: Heteroderidae)

Abstract


Cysts of Globodera rostochiensis (Wollenweber) Behrens from potato (Solanum tuberosum L.) fields and Heterodera cruciferae Franklin from cabbage (Brassica oleracea L. var. capitata subvar. rubra L.) fields and Heterodera schachtii Schmidt from sugar-beet (Beta vulgaris L.) fields in Turkey were collected and examined for the presence of fungi. Of the total of 196 cysts of G. rostochiensis, 39.7% were colonized by one or more of 7 different species of fungi, all of which were from the genera Cylindrocarpon, Fusarium, Gliocladium, Verticillium and Alternaria. Of the total of 136 cysts of H. cruciferae, 37.5% were colonized by one or more of 7 different species of fungi, all of which were from the genera Cylindrocarpon, Fusarium, Nematophthora, Periconia and Verticillium, and 38.9% of the 154 cysts of H. schachtii were colonized by one or more of 7 different species from the same genera.
