1 Fungicide treated plots received 3 fl oz/A Headline� at the 5 lf stage and 3 fl oz/A of Proline� plus 3 fl oz/A Folicur� when the varieties were in the early flowering stage.

2 Scab FS = Scab Field Severity which is calculated by multiplying the number of spikes infected by scab by the percent of the spike infected.

3 The least significant difference (LSD) values are for comparing variety means within a given fungicide treatment.

4 Significance level of the F-test for the variety by fungicide interaction. * = 5%, ** = 1%, N.S. = not significant at the 5% level.
