Optimizing metribuzin rates for herbicide-resistant Amaranthus weed control in soybean

Weed Technology
Palmer amaranth and waterhemp are troublesome weeds in U.S. corn, soybean, and cotton production systems. Rapid evolution of resistance to herbicide from multiple sites of action in these species warrant alternate weed control options. Metribuzin applied

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

Agrosystems, 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.

Commercial sprayer efficiency for application success on targeted weeds

Weed Technology
Commercial targeted sprayer systems allow producers to reduce herbicide inputs but risks the possibility of not treating emerging weeds. Currently, targeted applications with the John Deere system have five spray sensitivity settings, and no published ...

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

Frontiers 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.

Impact of soybean planting date and row width on weed suppression and yield

Agronomy Journal, Volume 117, Issue 5, September/October 2025.
Abstract Variable weather patterns and extended growing seasons over the last couple of decades have prompted growers to plant soybean [Glycine max (L.) Merr.] earlier than the historical standard. Field experiments were conducted in Michigan over three site‐years to evaluate soybean planting date, row width, and herbicide program on weed suppression ...

Responses of waterhemp and horseweed to cereal rye cover crop termination timing in soybean

Agrosystems, Geosciences & Environment
Field experiments were conducted in soybeans (Glycine max L.) to determine the effects of a cereal rye (Secale cereale L.) cover crop (CC), two CC termination timings (TTs), and four herbicide programs (HP) on the emergence, biomass, and seed production ...

Dose-response of common lambsquarters, redroot pigweed, and foxtail species to pyroxasulfone plus encapsulated saflufenacil applied preemergence to corn

Weed Technology
In September 2024, BASF Canada introduced a new premixture of pyroxasulfone and encapsulated saflufenacil to control weeds in corn production. Limited research has been conducted to determine the biologically effective dose of this new premixture for the

WeedRepFormer: Reparameterizable Vision Transformers for Real-Time Waterhemp Segmentation and Gender Classification

CoRR
We present WeedRepFormer, a lightweight multi-task Vision Transformer designed for simultaneous waterhemp segmentation and gender classification. Existing agricultural models often struggle to balance the fine-grained feature extraction required for biological attribute classification with the efficiency needed for real-time deployment. To address this,

Investigating the cost of adaptation in Amaranthus tuberculatus populations with evolved resistance to glyphosate [PDF]

Amaranthus tuberculatus (Common Waterhemp) is a prevalent, problematic weed in Midwestern USA, where genetically-modified crops are widely grown, resulting in multiple annual applications of glyphosate.

Amaranthus develops resistance to HPPD inhibitors in seed corn production fields - another example of lack of diversity in the weed control program

Julius-Kühn-Archiv, 2012
In 2010, a hybrid seed corn production field was confirmed to be infested with a population of Amaranthus tuberculatus that was not controlled by postemergence applications of all tested commercially available HPPDinhibitor herbicides.
