Confirmation of glyphosate-resistant waterhemp (Amaranthus tuberculatus) in New York

Weed Technology
Waterhemp has become a serious management challenge for field crop growers in New York. Two putative glyphosate-resistant (GR) waterhemp populations (NY1 and NY2) were collected in 2023 from two soybean fields in Seneca County, NY. The objectives of this

Evaluation of two‐pass herbicide programs for broad‐spectrum weed control in conventional tillage non‐transgenic corn production in Wisconsin atrazine prohibition areas

Agrosystems, Geosciences & Environment, 2023
Achieving effective weed control is crucial for Wisconsin conventional corn growers farming in atrazine prohibition areas. Upon request from our extension clientele, a field study was conducted at Arlington and Brooklyn, WI, in 2021 and 2022 (four site ...

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 ...

Automated approaches for the early stage distinguishing of Palmer amaranth from waterhemp

Frontiers in Agronomy
Palmer amaranth and waterhemp are two invasive pigweed species, which have become most troublesome to crops, especially corn and soybean. Among these two weed species, Palmer amaranth is more harmful to crops as it can grow faster, spread rapidly, and ...

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

Control of glyphosate-resistant waterhemp (Amaranthus tuberculatus) in dicamba - resistant soybean in New York

Weed Technology
Recent reports of glyphosate-resistant (GR) waterhemp pose serious concerns among crop producers in New York. Field experiments were conducted in 2019 and 2020 near Waterloo, New York, to evaluate the effectiveness of preemergence, postemergence ...

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 ...

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

Pest 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)

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.
