A multi-year experiment was established in Alabama and Georgia to identify effective integrated weed management strategies in peanut production. The objective of the study was to evaluate efficacy of tillage practices, cover crops, and various herbicide management options for weed control and peanut yield. The experiment consisted of three tillage treatments: conventional tillage, reduced tillage with a cover crop, and a winter fallow, reduced tillage treatment. Herbicide treatments included: Strongarm alone, Cadre alone, Valor alone, Strongarm plus Cadre, Valor plus Cadre, Valor plus Strongarm, Valor plus Cadre plus Strongarm, and a non­treated control. Experiment locations were at the Wiregrass Research Center in Headland, AL in 2014 and 2015 and at the Ponder Research Farm, TyTy, GA in 2014 and at the Lang-Rigdon farm in Tifton, GA in 2015. This report covers the Alabama 2015 location whereas GA submitted their report independently.
