Research on the pathogen components involved in Fusarium head blight (FHB) along with
the effects of their interactions on disease development and mycotoxin accumulation is
reviewed. The fungal components within the FHB complex differ significantly in different
environments. Individual species may respond differently to, and be differentially influenced
by, particular disease control measures. Almost all published co-inoculation studies on
wheat spikes or grains show that competitive interactions among FHB pathogens are the …
