Gene Duplication and Aneuploidy Trigger Rapid Evolution of Herbicide Resistance in Common Waterhemp [PDF]

Plant Physiology, 2018
An increase in gene copy number is often associated with changes in the number and structure of chromosomes, as has been widely observed in yeast and eukaryotic tumors, yet little is known about stress-induced chromosomal changes in plants. Previously, we reported that the EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) gene, the molecular target ...

Layered‐residual herbicide programs for waterhemp control in glufosinate‐resistant soybean

Crop, Forage & Turfgrass Management, 2023
Core Ideas Glufosinate is an important POST herbicide for waterhemp control in glufosinate‐resistant soybean. The layered‐residual herbicide approach improved season‐long waterhemp control. Glufosinate POST combined with layered soil residual herbicides improved season‐long waterhemp control.

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

Agronomy 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

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‐

Integrating early spring‐planted barley or oat for Palmer amaranth management in soybean

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Fall‐planted cover crops (CCs) are widely used for weed suppression, but CC establishment challenges after fall harvest in temperate regions necessitate alternative approaches. The objectives of this study were to evaluate the integrated effect of spring‐planted barley or oat CC and herbicide programs for CC biomass production, Palmer amaranth
