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 ...

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

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 ...

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

, 2021
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. Emergence and growth of waterhemp have been studied extensively in Iowa. Palmer amaranth (A.

Common Waterhemp Growth and Fecundity as Influenced by Emergence Date and Competing Crop

Agronomy Journal, 2007
Common waterhemp (Amarathus rudis Sauer) is a frequent weed in glyphosate‐resistant (GR) crops in the midwestern USA due, in part, to the delayed emergence of its seedlings. Variable waterhemp emergence was simulated by transplanting seedlings into both corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] and bare plot areas at differing crop growth

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)

Comparison of a diflufenican-containing premixture to current commercial standards for residual Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus) control

Weed Technology
With Palmer amaranth and waterhemp evolving resistance to nine and six different sites of action (SOAs) globally, soybean producers continue to search for new options to control these problematic weeds.

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

, 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

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.
