Evaluation of electrical and mechanical Palmer amaranth (<i>Amaranthus palmeri</i>) management in cucumber, peanut, and sweetpotato

Abstract Field studies were conducted to assess the efficacy of physical weed management Palmer amaranth in cucumber, peanut, and sweetpotato. Treatments arranged a 3 × 4 factorial which first factor included treatment method electrical, mechanical, or hand-roguing control second consisted treatments applied when was approximately 0.3, 0.6, 0.9, 1.2 m above crop canopy. Four wk after (WAT), electrical applications controlled at least 27 percentage points more than mechanical 0.3- 0.6-m timings. At 0.9- 1.2-m application timings WAT, by most 87%. Though hand removal generally resulted greatest peanut pod count total sweetpotato yield, similar yield hand-rogued plots, depending on timing. With additional research provide insight into optimal applications, there is potential for be used as alternatives removal.
