Biomass Yield Reductions in Switchgrass Due To Smut Caused by Tilletia maclaganii

P. M. Thomsen, E. C. Brummer, J. Shriver, and G. P. Munkvold

March 2008


Switchgrass is an attractive biomass crop for renewable energy, but there is little information on disease losses. A smut disease of switchgrass causes stunting, premature flowering, and replacement of seeds by fungal sori. The authors conducted a study in naturally-infested fields to describe the impact of smut on biomass yield. Ten fields were systematically sampled; smut incidence, stand density, and biomass yield were determined.
