Glyphosate- and multiple-resistant waterhemp (Amaranthus tuberculatus var. rudis) in Ontario, Canada [PDF]
Canadian Journal of Plant Science, 2017 Waterhemp is one of the most troublesome weeds in the US and is spreading into Ontario. In 2014, a waterhemp population was not controlled with glyphosate in a field in Lambton County, Ontario. This population was the first confirmed glyphosate-resistant (GR) waterhemp in Canada.

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 ...

Evaluation of the DJI AGRAS T40 UAV for application of herbicides in soybean
Weed TechnologyThe use of unmanned aerial vehicles (UAVs) shows promise as a potential new way to apply herbicides; however, relatively few studies have been conducted to determine how UAV application parameters influence spray deposition and weed control.

Responses of waterhemp and horseweed to cereal rye cover crop termination timing in soybean
Agrosystems, Geosciences & EnvironmentField experiments were conducted in soybeans (Glycine max L.) to determine the effects of a cereal rye (Secale cereale L.) cover crop (CC), two CC termination timings (TTs), and four herbicide programs (HP) on the emergence, biomass, and seed production ...

Restoration Ecology, Volume 33, Issue 7, September 2025.Seed‐based restoration is a viable method for alleviating the loss of tallgrass prairies by creating new assemblages of prairie flora. Despite using diverse inputs of native seeds, restoration efforts frequently fall short of plant diversity goals.

Interventions for weed seed management in cotton around the harvest time
Weed TechnologyLate-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 TechnologyPalmer 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
