Managing herbicide-resistant waterhemp (Amaranthus tuberculatus) in Midwestern United States soybean systems [PDF]
, 2023 Weed infestations, namely herbicide-resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) prevent growers from achieving optimal yields; therefore, growers are seeking tactics to reduce or prevent crop-weed competition.

Journal of Field Robotics, Volume 43, Issue 3, Page 1973-1987, May 2026.ABSTRACT Sustainable weed management necessitates herbicide‐reduced, precision weed control. Recent advancements in machine vision and artificial intelligence (AI) for weed recognition and localization have created new opportunities for high‐precision weeding. Although blanket spraying systems are widely used for weed removal, machine vision‐guided, AI‐
