Agricultural adaptation in the native North American weed waterhemp, Amaranthus tuberculatus (Amaranthaceae). [PDF]
PLoS ONE, 2020 There is increasing interest in documenting adaptation of weedy plant species to agricultural ecosystems, beyond the evolution of herbicide resistance. Waterhemp (Amaranthus tuberculatus) is a native plant of the Midwestern U.S.

Automated approaches for the early stage distinguishing of Palmer amaranth from waterhemp [PDF]
Frontiers in AgronomyPalmer amaranth and waterhemp are two invasive pigweed species, which have become most troublesome to crops, especially corn and soybean. Among these two weed species, Palmer amaranth is more harmful to crops as it can grow faster, spread rapidly, and ...

Managing herbicide‐resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) seedbanks by integrating several management tactics [PDF]
Agrosystems, Geosciences & Environment, 2023 Herbicide‐resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) continues to threaten the productivity of many US crops. Thus, integrating non‐herbicidal tactics with herbicides to reduce weed seedbanks is gaining popularity.

Growth and development of multiple waterhemp (Amaranthus tuberculatus) cohorts in corn and soybeans
Frontiers in Agronomy, 2022 Waterhemp is a troublesome weed species in cropping systems throughout Wisconsin and much of the US Midwest. Coupled with extended emergence window, rapid growth, high genetic diversity, and herbicide resistance to multiple sites of action, waterhemp ...

Do Traits Travel? Multiple-Herbicide-Resistant A. tuberculatus, an Alien Weed Species in Israel [PDF]
Plants, 2023 Amaranthus tuberculatus is the most common weed in soybean and corn in the USA and Canada. In Israel, it has been a minor riverbank weed. However, in recent years, growing densities of this plant have been observed in field crops, orchards, and roadsides.

Quantifying resistance to very-long-chain fatty acid-inhibiting herbicides in Amaranthus tuberculatus using a soilless assay. [PDF]
PLoS ONE, 2023 Resistance to preemergence (PRE) soil-applied herbicides, such as inhibitors of very-long-chain fatty acid (VLCFA) elongases, was documented in two waterhemp [Amaranthus tuberculatus (Moq.) J.D. Sauer] populations (SIR and CHR) from Illinois, USA.
