Interspecies interactions between Fusarium avenaceum, Fusarium culmorum, Fusarium graminearum,
Fusarium poae, and Fusarium tricinctum were studied during early growth stages of
isolates on model surfaces. Additionally, germination and germ tube growth of the pathogens
were studied on attached and detached wheat leaves at 10 C and 22 C. Two-species
interactions between Fusarium isolates during germination and germ tube growth were assessed
after 8 hours of incubation. All species except F. tricinctum germinated and grew
faster at higher than lower temperature. All species were able to germinate with more
than one germ tube per conidium cell; and germination and germ tube growth were faster
on leaves than on glass surface. Interactions among Fusarium species during germination
and germ tube growth were predominantly competitive with macroconidia-producing species
being more competitive. It is concluded that the type of conidia as well as environmental
factors influence the competitiveness of Fusarium species during early stages of growth.
