Dash - Range in reaction on each plant. Range in severity between plant but same reaction class. Natural Inoculum - Readings were made on flag and flag minus I at milk to mid dough stage. 2 = C.I. - Average Coefficient of Infection. Percent severity multiplied by the following values for reaction types.R=0.2, MR=0.4, MS=0.8, S=1.0, t=0.5.
