Effect of tillage and corn row spacing on common waterhemp growth and fecundity

, 2020
The acceptance of integrated weed management programs has been hindered by a lack of information on crop-weed interactions. Four experiments were conducted in central Iowa during 2001 and 2002 in corn planted in 38 and 76 cm rows to determine the response of common waterhemp (Amaranthus rudis Sauer) growth parameters to corn (Zea mays) row spacing and ...

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.

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.

Herbicide strategies for weed control in Wisconsin conventional-tillage corn production systems

Weed Technology
Selection of effective herbicide strategies (i.e., one-pass versus two-pass and timing [preemergence versus postemergence]) is of great importance to corn growers.

Pervasive weed management and soybean yield with 2,4-D and glufosinate applied alone, mixed, or sequentially

Weed Technology
Field experiments were conducted near Beresford and South Shore, South Dakota, in 2023 and 2024, to determine weed control and soybean yield with 2,4-D and glufosinate applied individually, together, and sequentially. Herbicides were sequentially applied

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
