Tolerance of little bluestem to ACCase‐inhibiting herbicides in Pennsylvania

Abstract

Core Ideas ACCase‐inhibiting herbicides cause foliar injury and stunting of little bluestem culms/inflorescences. Sethoxydim, fluazifop, and quizalofop cause moderate to severe foliar injury on little bluestem. Sethoxydim, fluazifop, and quizalofop cause severe stunting of little bluestem culms/inflorescences. Fenoxaprop produces only minor foliar injury and moderate stunting of little bluestem culms/inflorescences. Fenoxaprop produced less foliar injury and stunting than sethoxydim, fluazifop, and quizalofop.
