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

A point mutation in IAA34 confers resistance to the auxin herbicide 2,4‐D in Sisymbrium orientale

Pest Management Science, Volume 81, Issue 7, Page 3523-3531, July 2025.
A point mutation in domain IV of SoAux/IAA34‐R provides resistance to 2,4‐D. Abstract BACKGROUND Sisymbrium orientale has evolved resistance to 2,4‐D in Australia due to a 27 bp deletion in SoIAA2. However, one population of Sisymbrium orientale resistant to 2,4‐D (R1) did not contain the SoIAA2Δ27, suggesting another 2,4‐D resistance mechanism was ...

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.

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,

GM Crops and the Jevons Paradox: Induced Innovation, Systemic Effects and Net Pesticide Increases From Pesticide‐Decreasing Crops

Journal of Agrarian Change, Volume 25, Issue 3, July 2025.
ABSTRACT The Jevons paradox describes how increased efficiency in the use of a resource can paradoxically increase rather than reduce its overall consumption. In agricultural systems, efficiency is confounded by a broad range of economic, ecological, social and evolutionary factors. Agriculture is a particularly elastic kind of production: Efficiencies

Influence of deer repellent and herbicide combinations on weed control and deer browsing in soybean

Weed Technology
Preventing white-tailed deer from browsing on crops and resulting in lower crop yields has been a challenge within agriculture for several decades. In an effort to reduce the soybean losses incurred by deer browsing, several wildlife repellents have been

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

Waterhemp update

, 1998
It was reported in the July 20 ICM newsletter (pages 146-147) that there were several incidents where weeds were not controlled by Roundup Ultra. Mention was made of a specific field near Everly, Iowa, where common waterhemp was surviving 3 applications ...
