Biomass Yield Reductions in Switchgrass Due To Smut Caused by <i>Tilletia maclaganii</i>

Fig. 6. Relationship between disease incidence and biomass yield loss for smut caused by Tilletia maclaganii in switchgrass, based on 50 strip plot yields from 10 fields in southern Iowa in 2002. Each data point represents the mean of three 1-m² subsamples.
