Interaction of Pyroxasulfone and Encapsulated Saflufenacil Applied Preemergence for Control of Waterhemp in Corn

Journal of Agricultural Science
Waterhemp is a problematic weed in corn production that is rapidly evolving multiple herbicide resistance; 5-way resistance to herbicide groups 2, 5, 9, 14 and 27 has been confirmed in multiple counties across southern Ontario. The introduction of a new premix herbicide, pyroxasulfone plus encapsulated saflufenacil, provides growers with an additional ...

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.

Effect of herbicide application timing and sequence on waterhemp (Amaranthus tuberculatus) and common lambsquarters (Chenopodium album) control, Enlist E3® soybean yield, and economic returns

Weed Technology
Enlist E3® soybean is resistant to 2,4-D, glyphosate, and glufosinate, allowing postemergence applications of these herbicides sequentially or as tank mixes.

Profile and extent of herbicide-resistant waterhemp (Amaranthus tuberculatus) in Minnesota

Weed Science
AbstractInformation regarding the prevalence and distribution of herbicide-resistant waterhemp [Amaranthus tuberculatus (Moq.) Sauer] in Minnesota is limited. Whole-plant bioassays were conducted in the greenhouse on 90 A. tuberculatus populations collected from 47 counties in Minnesota.

Waterhemp breaking through soybean canopy [PDF]

, 1999
The past week I received several calls concerning waterhemp that was just beginning to break through the soybean canopy. The callers were wondering whether it is worth making another application for these weeds; the answer is "no." They also wanted to ...

Dicamba-based preemergence herbicide tank mixtures improved residual weed control in dicamba-resistant soybean

Frontiers in Agronomy
In February 2024, the United States Environmental Protection Agency (EPA) vacated the registrations of dicamba products for over-the-top applications on dicamba-resistant cotton and soybean following a court ruling.

Multi-state assessment of electrocution for late-season weed control in soybean in the Central United States

Weed Technology
The increasing prevalence of herbicide-resistant weeds underscores the need to integrate non- chemical weed management approaches in soybean. Weed electrocution may be a viable option; however, limited research exists on the subject.

Control of multiple-herbicide-resistant waterhemp with acetochlor-based herbicide mixtures in soybean

Weed Technology
Abstract Waterhemp has evolved resistance to Group 2, 5, 9, 14, and 27 herbicides in Ontario, Canada, making control of this challenging weed even more difficult. Acetochlor is a Group 15, chloroacetanilide herbicide that has activity on many small-seeded annual grasses and some small-seeded annual broadleaf weeds, including waterhemp. The objective
