Achieving Full-season Waterhemp Control in Soybean [PDF]
, 2019 Although there are many ways weeds escape control in crop fields, one of the leading causes of waterhemp control failures is emergence of plants following postemergence herbicide (POST) treatments.

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

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

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.

Factors leading to inconsistent waterhemp control [PDF]
, 2002 Waterhemp continues to be one of the most problematic weeds for Iowa farmers. A higher frequency of waterhemp escapes was observed in Roundup Ready soybean fields during 2001 than in previous years.

Weed seed destructor: A harvest weed seed control method to manage waterhemp in soybean [PDF]
, 2023 Waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) is the most common and troublesome weed in soybean (Glycine max [L.] Merr.) based cropping systems of the Midwestern United States (U.S.). Evolution of multiple herbicide resistance in waterhemp is an

CoRRWe 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.
