Bioassays were used to determine the production of DON by two isolates of Fusarium graminearum when grown in association with potentially competitive fungi and an antifungal chemical, B – pentylol – pyrone (6PAP). The presence of 6PAP in the culture medium reduced DON production by as much as 80%. A 6PAP – producing Trichoderma isolate grown in a competition assay system with the F. graminearum isolates was also able to substantially reduce DON production. When Fusarium isolates (F. crookweelense, F.culmorum,F. subglutinans, F. poae, F.equiseti, F.avendceum and F.sambucinum), which co – occur with F. graminearum in New Zealand maize plants, were grown in competitio assays, the effect on DON production was variable. However, all isolates of F. sublutinans tested were shown to cause reductions in DON production by 13 – 76% (mean = 62%).
