Prediction of cereal rye biomass accumulation in Wisconsin based on weather and agronomic management
Abstract Cereal rye (Secale cereale L.) biomass accumulation is strongly influenced by weather conditions and management practices, making accurate biomass estimates critical for guiding farmers’ management decisions. In this study, we evaluated how weather (e.g., temperature and rainfall) and management practices (including planting and termination ...

Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Factors leading to inconsistent waterhemp control [PDF]
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.

Metabolism‐based atrazine‐resistant Amaranthus tuberculatus populations ACR and MCR exhibit little or no cross‐resistance to amicarbazone and metribuzin, suggesting that non‐halogenated Group 5 herbicides can be utilized to re‐establish effective control.

Research Report: Prevalence and Mechanism of Atrazine Resistance in Waterhemp from Nebraska [PDF]
Waterhemp is a troublesome summer annual broadleaf weed species that has evolved resistance to glyphosate and other herbicide sites of action (SOA) in Nebraska, including to groups 2 (i.e., Classic, Pursuit, FirstRate), 4 (i.e., 2, 4-D), 5(i.e., atrazine)

Targeted herbicide application technology performance depends on sprayer configuration. Across five studies, activation of multiple, overlapping nozzles and maintaining appropriate boom height consistently improved spray coverage and weed control, highlighting the importance of optimized sprayer setup for effective and reliable weed control.
