Insecticide Applications have Minor Effects on Switchgrass Biomass Yield

Large‐scale production of switchgrass ( Panicum virgatum L.) as a bioenergy crop will depend on producing abundant yields without significant loss to insects. Despite the fact that crop losses to insect pests are observed in virtually every crop grown, we know little of how insects affect switchgrass biomass yield. We performed two multi‐year experiments in South‐Central Wisconsin where we measured Hiawatha switchgrass biomass responses to...
