Evaluation of Acetochlor for Control of Multiple-Herbicide-Resistant Waterhemp (Amaranthus tuberculatus (Moq.) J.D. Sauer) in Ontario Crops

open access: yes, 2023
Twenty-five field trials were conducted in 2021 and 2022 to evaluate multiple-herbicide-resistant waterhemp control with acetochlor. Phaseolus vulgaris dry beans, corn, and soybean were tolerant to acetochlor; tank mixing acetochlor and flumioxazin ...

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

open access: yesCrop, 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 ...

Performance of Preemergence Herbicides on Waterhemp Control in Soybean

open access: yes, 2020
The battle against waterhemp is complicated mainly because of its extended emergence period (early May until August). Preemergence (PRE) soil residual herbicides serve as a foundation for managing waterhemp, but require follow-up treatments with ...

Herbicide Programs for Waterhemp Control in Soybean

open access: yes, 2021
Waterhemp is a dioecious (male and female flowers on separate plants) pigweed with a high genetic diversity. Consequently, this pigweed has a high propensity to adapt to control tactics and has evolved resistance to herbicides from as many as 6 or 7 ...

Soybean (Glycine max L.) canopy response to simulated dicamba vapor drift using unmanned aerial sensing

open access: yesPest Management Science, Volume 81, Issue 10, Page 6139-6149, October 2025.
Sensitive soybean canopies subjected to 0.056 g a.e. ha−1 dicamba were identifiable 8 days after treatment using UAS correlating to visible and nonvisible portions of the electromagnetic spectrum. Abstract BACKGROUND Concerns about off‐target dicamba exposure to sensitive vegetation have escalated following the commercialization of dicamba‐tolerant (DT)

Comparative analysis of Palmer amaranth (Amaranthus palmeri) and waterhemp (A. tuberculatus) in Iowa

open access: yes, 2022
Waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer), a native to the Midwestern United States, is difficult to control in crops and has become resistant to several herbicides.

Inheritance of Mesotrione Resistance in an Amaranthus tuberculatus (var. rudis) Population from Nebraska, USA

open access: yesFrontiers in Plant Science, 2018
A population of Amaranthus tuberculatus (var. rudis) evolved resistance to 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicides (mesotrione, tembotrione, and topramezone) in Nebraska.

Interactions between glyphosate, Fusarium infection of waterhemp, and soil microorganisms [PDF]

open access: yes, 2018
In recent years, an increasing number of weed populations have been characterized with resistance to the herbicide glyphosate. In particular, waterhemp has evolved glyphosate resistance (GR) across numerous soybean fields in Missouri. Therefore research is needed to determine best management practices for GR weed biotypes.

Termination strategies for high biomass cereal rye cover crop in soybean planting green systems

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Weed management programs utilizing high‐biomass cereal rye (Secale cereale L.) cover crop in Wisconsin soybean [Glycine max (L.) Merr.] production systems are increasing in popularity. Much of this method's success depends on effective cereal rye termination and environmental conditions in the spring.
