Managing herbicide-resistant waterhemp (Amaranthus tuberculatus) in Midwestern United States soybean systems [PDF]

open access: yes, 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.

Brassica biofumigation cover crops in US agroecosystems: A systematic review of research from 2014 to 2024

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Biofumigation with brassica cover crops (BCCs) is gaining momentum in the United States as an ecologically sound alternative to chemical pest suppression in agricultural systems. This review critically evaluates the impacts of Brassica species on soil health, weed suppression, disease mitigation, and control of plant‐parasitic nematodes (PPNs)

Development and Preliminary Evaluation of a Machine Vision‐Guided Smart Sprayer Prototype Toward Precision Vegetable Weeding

open access: yesJournal 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‐
