Research Report: Prevalence and Mechanism of Atrazine Resistance in Waterhemp from Nebraska [PDF]

, 2018
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)

Control of Glyphosate-Resistant Common Waterhemp (Amaranthus rudis) in Glufosinate-Resistant Soybean

, 2017
Glyphosate-resistant (GR) common waterhemp has become a significant problem weed in Nebraska and several Midwestern states. Several populations of GR common waterhemp are also resistant to acetolactate synthase (ALS)-inhibiting herbicides, making them ...

Influence of saflufenacil encapsulation on corn phytotoxicity and residual broadleaf weed control

Weed Technology
Saflufenacil, a herbicide that inhibits protoporphyrinogen oxidase, has been reformulated as a microencapsulation for preemergence and postemergence applications to corn, with the primary purpose of the encapsulation to reduce the risk of corn injury ...

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.
