Management Considerations for Palmer Amaranth in a Northern Great Plains Soybean Production System

Agrosystems, Geosciences & Environment, 2019
Core Ideas Soybean yield loss in South Dakota was dependent on Palmer amaranth density if it emerged before canopy closure. Soybean yield losses were not Palmer amaranth density dependent when it emerged at the R2 soybean growth stage.

Multi-tactic ecological strategies to manage Bassia scoparia and Amaranthus tuberculatus in the cropping systems of Great Plains and Midwestern U.S. [PDF]

, 2022
Kochia (Bassia scoparia [L.] A.J. Scott) and waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) are one of the most troublesome weeds in the cropping systems of Great Plains and Midwestern United States, respectively.

Projected Range Shifts of Emerging Agricultural Weeds Under Climate Change in Central Europe

Weed Research, Volume 66, Issue 3, May/June 2026.
ABSTRACT Assessing which weed species are likely to expand under climate change is essential for proactive management. While climate‐driven range expansions of many weed species have been documented globally, projections for their future spread in Central Europe remain limited and poorly understood.

The influence of multiple herbicide resistance on growth and development of Amaranthus tuberculatus and the efficacy of the very long chain fatty acid-inhibiting herbicides on multiple herbicide-resistant Amaranthus tuberculatus; Investigating a putative 4-hydroxylphenylpyruvate dioxygenase-inhibiti [PDF]

, 2018
Iowa farmers rely mainly on herbicides for weed management. Inconsistent and unsatisfactory weed control is being realized as the spread of herbicide-resistant weed populations has increased.

Targeted herbicide cost requirements for adoption of See & Spray technology and ways to improve area sprayed

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Adopting targeted herbicide applications creates a dynamic problem for producers when considering the economic viability of See & Spray. Research was conducted to estimate how weed area, area sprayed, nozzle selection, sensitivity settings, crops, and regions influence potential herbicide savings with the John Deere See & Spray technology ...

Distribution of target site PPO-inhibiting herbicide resistance mutations in waterhemp and Palmer amaranth and association of epyrifenacil efficacy with PPX2 target site variants

Weed Technology
During the 2019 growing season, seeds of Palmer amaranth and common waterhemp were collected from 141 and 133 agricultural sites, respectively, from across the southeastern and midwestern United States.

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

Herbicide programs for control of a five‐way herbicide resistant waterhemp population in Xtendflex or Enlist E3 soybean

Crop, Forage &Turfgrass Management, Volume 11, Issue 2, December 2025.
Abstract Waterhemp [Amaranthus tuberculatus (Moq.) J.D. Sauer] is one of the most problematic weeds in soybean [Glycine max (L.) Merr.] production in the Midwestern United States. In recent years, the adoption of soybean resistant to dicamba, 2,4‐D, and/or glufosinate have enabled the use of these herbicides to improve control of problematic weeds ...
