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.

Distribution of target site PPO-inhibiting herbicide resistance mutations in waterhemp and Palmer amaranth and association of epyrifenacil efficacy with PPX2 target site variants

Weed Technology
During the 2019 growing season, seeds of Palmer amaranth and common waterhemp were collected from 141 and 133 agricultural sites, respectively, from across the southeastern and midwestern United States.

Genetic and physiological characterization of seed dormancy regulation in common waterhemp [Amaranthus tuberculatus (Moq) Sauer]

, 2018
Common waterhemp [Amaranthus tuberculatus (Moq.) Sauer.] is an annual plant native to the Midwest United States and is considered a troublesome weed species. The economic importance of common waterhemp is attributable to rapid population increases, the appearance of herbicide resistant biotypes, and the emergence phenology during the cropping season ...

Impact of soybean planting date and row width on weed suppression and yield

Agronomy Journal, Volume 117, Issue 5, September/October 2025.
Abstract Variable weather patterns and extended growing seasons over the last couple of decades have prompted growers to plant soybean [Glycine max (L.) Merr.] earlier than the historical standard. Field experiments were conducted in Michigan over three site‐years to evaluate soybean planting date, row width, and herbicide program on weed suppression ...

Cereal rye biomass effects on giant ragweed suppression inform management decisions

Agrosystems, Geosciences &Environment, Volume 8, Issue 1, March 2025.
Abstract Giant ragweed (Ambrosia trifida L.) has become one of the most troublesome weeds across the US Midwest partially due to its early emergence, high competitiveness, and herbicide resistance evolution. This study aimed to determine the amount of cereal rye (Secale cereale L.) biomass needed to suppress giant ragweed establishment and growth.

Sensitivity of difficult‐to‐control Palmer amaranth accessions to fluridone and diflufenican

Agronomy Journal, Volume 117, Issue 1, January/February 2025.
Abstract Palmer amaranth (Amaranthus palmeri S. Watson) has evolved resistance to herbicides targeting nine sites of action. Phytoene desaturase‐inhibiting herbicides remain among the few sites of action that are still effective in controlling Palmer amaranth.

Influence of glufosinate mixtures on waterhemp control and soybean canopy and yield

Weed Technology
Glufosinate serves as both a primary herbicide option and a complement to glyphosate and other postemergence herbicides for managing herbicide-resistant weed species.

Survey of glufosinate use in soybean production in Arkansas and Wisconsin

Weed Technology
Glufosinate is a key postemergence herbicide in U.S. soybean production, particularly where resistance to glyphosate and inhibitors of acetolactate synthase is widespread.

Interventions for weed seed management in cotton around the harvest time

Weed Technology
Late-season escapes of Palmer amaranth and waterhemp (both are Amaranthus species) pose a significant challenge in cotton production due to their high fecundity, herbicide resistance, and ability to replenish the weed seedbank at harvest.

Optimizing metribuzin rates for herbicide-resistant Amaranthus weed control in soybean

Weed Technology
Palmer amaranth and waterhemp are troublesome weeds in U.S. corn, soybean, and cotton production systems. Rapid evolution of resistance to herbicide from multiple sites of action in these species warrant alternate weed control options. Metribuzin applied
