Quizalofop-p-ethyl Mixed with Synthetic Auxin and ACCase-Inhibiting Herbicides for Weed Management in Rice Production

International Journal of Agronomy, 2019
A study was conducted near Crowley, Louisiana, to evaluate the efficacy of quizalofop-p-ethyl mixed with different synthetic auxin and ACCase-inhibiting herbicides for barnyardgrass and weedy rice control in rice production systems.

Deep learning‐based laser weed control compared to conventional herbicide application across three vegetable production systems

Pest Management Science, Volume 81, Issue 8, Page 4922-4936, August 2025.
In 2024, trials in New Jersey and New York evaluated the effectiveness of laser weeding with a Carbon Robotics unit compared with herbicides on beets, spinach, and peas. Results demonstrated that laser weeding was as effective or superior to herbicides in controlling weeds, reducing biomass by ≥97% and boosting crop growth by ≥30%.

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 ...

Evaluation of postharvest age and dormancy-breaking methods on Echinochloa crus-galli seed germination

Bioscience Journal
Barnyardgrass (Echinochloa crus-galli) is one of the most troublesome weeds in irrigated rice cultivation and has increasingly impacted rainfed crops due to the emergence of herbicide-resistant populations.

Soil residual activity of tetflupyrolimet and the influence of soil moisture and flood timeliness on barnyardgrass efficacy

Weed Technology
Tetflupyrolimet is the first herbicide with a novel site of action to be commercialized for use in agronomic crops in three decades. Direct-seed rice field experiments were conducted at research facilities near Stuttgart (silt loam), AR, and Keiser (clay)

Assessing impacts of drought on weed communities in the Great Lakes region

Weed Research, Volume 65, Issue 3, May/June 2025.
Abstract Drought can alter weed occurrence, interference with crops, and act as ecological filters altering community structure. Precipitation patterns in the Great Lakes region of the United States are predicted to vary due to climate change, and understanding the impact of drought on weed communities can support effective management practices.

Weed emergence patterns as affected by topsoil movement within an eroded landform

Agronomy Journal, Volume 117, Issue 2, March/April 2025.
Abstract Soil erosion significantly affects within‐field soil properties, crop productivity, weed emergence patterns, and weed growth. Spatial variability in weed densities, emergence timing, weed seed production, seed viability, herbicide bioavailability, and other factors complicate weed management strategies in eroded landscapes.

Grass weeds control in transplanted rice with Cyhalofop-butyl

Journal of Crop Protection, 2022
This experiment was performed to determine the appropriate dose of Cyhalofop-butyl (CB) for controlling grass weeds in transplanted rice. CB at four doses, including 50, 100, 150, and 200 g ai/ha was investigated and compared with current herbicides in ...
