Automated approaches for the early stage distinguishing of Palmer amaranth from waterhemp

Frontiers in Agronomy
Palmer 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 ...

Influence of glufosinate mixtures on waterhemp control and soybean canopy and yield

Weed Technology
Glufosinate serves as both a primary herbicide option and a complement to glyphosate and other postemergence herbicides for managing herbicide-resistant weed species.

Mapping of flumioxazin tolerance in a snap bean diversity panel leads to the discovery of a master genomic region controlling multiple stress resistance genes [PDF]

Frontiers in Plant Science
IntroductionEffective weed management tools are crucial for maintaining the profitable production of snap bean (Phaseolus vulgaris L.). Preemergence herbicides help the crop to gain a size advantage over the weeds, but the few preemergence herbicides ...

Carfentrazone-ethyl resistance in an Amaranthus tuberculatus population is not mediated by amino acid alterations in the PPO2 protein. [PDF]

PLoS ONE, 2019
To date, the only known mechanism conferring protoporphyrinogen IX oxidase (PPO)-inhibitor resistance in waterhemp (Amaranthus tuberculatus) is a glycine deletion in PPO2 (ΔG210), which results in cross-resistance to foliar PPO-inhibiting herbicides ...

Changing Landscape of Waterhemp Herbicide Resistance in Wisconsin: A Comparative Analysis Over Time

Weed Technology
A comprehensive assessment of herbicide resistance in waterhemp accessions to commonly used corn and soybean herbicides over time is crucial for documenting shifts in herbicide resistance patterns and identifying effective management options.

Studying the Effects of Waterhemp Competition on Yield and Phytochemical Content of High-cannabidiol Hemp in Plasticulture

HortTechnology, 2022
The impacts of weed interference on hemp (Cannabis sativa) yield are largely unstudied despite causing serious economic losses in most cropping systems.

Managing herbicide‐resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) seedbanks by integrating several management tactics

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.

Investigating the Efficacy of Selected Very-Long-Chain Fatty Acid-Inhibiting Herbicides on Iowa Waterhemp (Amaranthus tuberculatus) Populations with Evolved Multiple Herbicide Resistances

Agronomy, 2021
Very long chain fatty acid (VLCFA)-inhibiting herbicides (Herbicide group (HG) 15) have been applied to corn and soybean fields in Iowa since the 1960s.

Evaluation of foliar‐applied post‐emergence corn–soybean herbicides on giant ragweed and waterhemp control in Wisconsin

Agrosystems, Geosciences & Environment, 2023
Giant ragweed (Ambrosia trifida L.) and waterhemp (Amaranthus tuberculatus [Moq.] J.D.Sauer) are highly competitive and the most troublesome weeds in corn (Zea mays L.) and soybean (Glycine max Merr.) cropping systems in Wisconsin. Field experiments were
