N2  - In Fusarium culmorum-inoculated field trials, a significant regression relationship was found between incidence and severity of fusarium ear blight (FEB), and between % infected spikelets and 1000 grain weight of wheat. In cv. Avalon, an estimated 0.5 t ha-l would be lost for every 10% increase in the disease. In glasshouse trials, the most effective fungicidal control of F. culmorum infection of wheat ears was demonstrated by tebuconazole and prochloraz, applied 7 days prior to inoculation. The variable retention of a sodium fluoroscein tracer was demonstrated on the ears of a range of wheat cultivars, and scanning electron microscope studies showed massive internal colonization of protected surfaces prior to the appearance of visible symptoms. These factors may help to explain variability in fungicide performance. A link between height and FEB resistance in wheat cultivars was demonstrated
