Other claims from this paper (6)
- Intervention effect F. graminearum GA18W 3.1.4 produced higher Fusarium-damaged kernels than pooled F. poae on wheat and barley.
- Intervention effect F. graminearum GA18W 3.1.4 reduced thousand-kernel weight to 18 g, compared with pooled F. poae on wheat and barley.
- Intervention effect No consistent differences in disease were detected among the four F. poae isolates on wheat and barley.
- Association Isolate, cultivar and inoculation method had significant main effects on SEV, FDK and TKW.
- Observation Fusarium poae can contribute to Fusarium head blight in US small-grain cereals.
- Recommendation The authors support considering F. poae in resistance screening programmes for small-grain cereals.
