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

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 ...

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 ...

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 ...

Targeted herbicide spraying systems: role of nozzle type, number of nozzle activation, nozzle orientation, and boom height on spray coverage and weed control. [PDF]

Pest Manag Sci
Targeted herbicide application technology performance depends on sprayer configuration. Across five studies, activation of multiple, overlapping nozzles and maintaining appropriate boom height consistently improved spray coverage and weed control, highlighting the importance of optimized sprayer setup for effective and reliable weed control.

Target-site and non-target-site mechanisms confer multiple herbicide resistance in waterhemp (Amaranthus tuberculatus) accessions from Wisconsin. [PDF]

Pest Manag Sci
The A101 accession is the first confirmed case of hydroxyphenyl pyruvate dioxygenase resistance in Amaranthus tuberculatus in Wisconsin, and the first report of P450s associated with atrazine resistance in A. tuberculatus globally. Abstract BACKGROUND A preliminary screening identified a multiple herbicide‐resistant waterhemp, Amaranthus tuberculatus ...

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.

Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism. [PDF]

Plant Direct
ABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.
