Different nontarget‐site mechanisms underlie resistance to dicamba and 2,4‐D in an Amaranthus tuberculatus population [PDF]

Pest Management Science
Weak phenotypic and genetic associations between resistance to dicamba and 2,4‐D suggest that different nontarget‐site mechanisms contribute to these traits in an Amaranthus tuberculatus population from Illinois. Abstract BACKGROUND Amaranthus tuberculatus (Moq.) Sauer (waterhemp) has emerged as one of several weed species that is resistant to ...

Draft Genomes of Amaranthus tuberculatus, Amaranthus hybridus, and Amaranthus palmeri [PDF]

Genome Biology and Evolution, 2020
Amaranthus tuberculatus, Amaranthus hybridus, and Amaranthus palmeri are agronomically important weed species. Here, we present the most contiguous draft assemblies of these three species to date.

Will the Amaranthus tuberculatus Resistance Mechanism to PPO-Inhibiting Herbicides Evolve in Other Amaranthus Species? [PDF]

International Journal of Agronomy, 2012
Resistance to herbicides that inhibit protoporphyrinogen oxidase (PPO) has been slow to evolve and, to date, is confirmed for only four weed species. Two of these species are members of the genus Amaranthus L. Previous research has demonstrated that PPO-

Palmer amaranth (Amaranthus palmeri S. Wats.) and waterhemp (Amaranthus tuberculatus (Moq.) J.D. Sauer) biovigilance in Canadian Agro-ecosystems [PDF]

Canadian Journal of Plant Science
The evolution and spread of herbicide-resistant weeds threatens long-term sustainability of Canadian agro-ecosystems. Herbicide-resistant weeds increase management inputs and costs, increase off-target and environmental exposure to pesticides, reduce yield quality and quantity, and impede harvest efficiency.

Evaluation of single versus multiple site of action preemergence herbicides for waterhemp and giant ragweed control in Wisconsin soybean

Agrosystems, Geosciences & Environment
The use of preemergence (PRE) herbicides with soil residual activity is recognized as an effective strategy for early‐season weed management in Midwest US soybean [Glycine max (L.) Merr.] production. The efficacy of soybean PRE herbicides with single and

Responses of waterhemp and horseweed to cereal rye cover crop termination timing in soybean

Agrosystems, Geosciences & Environment
Field 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 ...

Evaluating precision sprayers for targeted weed management in corn and soybean

Agrosystems, Geosciences & Environment
A targeted application of herbicides in commercial crop fields is desirable for reducing chemical inputs and promoting environmental sustainability. Precision sprayers, equipped with cameras and sensors, detect weeds in real‐time and apply herbicides ...

Metabolic Pathway of Topramezone in Multiple-Resistant Waterhemp (Amaranthus tuberculatus) Differs From Naturally Tolerant Maize [PDF]

Frontiers in Plant Science, 2018
Waterhemp [Amaranthus tuberculatus (Moq.) Sauer] is a problematic dicot weed in maize, soybean, and cotton production in the United States. Waterhemp has evolved resistance to several commercial herbicides that inhibit the 4-hydroxyphenylpyruvate ...

Non-triazine photosystem II inhibitors provide effective control of metabolic atrazine-resistant Amaranthus tuberculatus. [PDF]

Pest Manag Sci
Metabolism‐based atrazine‐resistant Amaranthus tuberculatus populations ACR and MCR exhibit little or no cross‐resistance to amicarbazone and metribuzin, suggesting that non‐halogenated Group 5 herbicides can be utilized to re‐establish effective control.
