Gene Duplication and Aneuploidy Trigger Rapid Evolution of Herbicide Resistance in Common Waterhemp [PDF]

open access: yesPlant Physiology, 2018
An increase in gene copy number is often associated with changes in the number and structure of chromosomes, as has been widely observed in yeast and eukaryotic tumors, yet little is known about stress-induced chromosomal changes in plants. Previously, we reported that the EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) gene, the molecular target ...

Management Options and Factors Affecting Control of a Common Waterhemp (Amaranthus rudis) Biotype Resistant to Protoporphyrinogen Oxidase-Inhibiting Herbicides

open access: yesInternational Journal of Agronomy, 2012
Repeated use of protox-inhibiting herbicides has resulted in a common waterhemp (Amaranthus rudis Sauer) biotype that survived lactofen applied up to 10 times the labeled rate.

Herbicide Programs for Waterhemp Control in Soybean [PDF]

open access: yes, 2021
Waterhemp is a dioecious (male and female flowers on separate plants) pigweed with a high genetic diversity. Consequently, this pigweed has a high propensity to adapt to control tactics and has evolved resistance to herbicides from as many as 6 or 7 ...

Influence of Broadcast Nozzle Design and Weed Density on Dicamba Plus Glyphosate Deposition, Coverage, and Efficacy in Dicamba-Resistant Soybean

open access: yesFrontiers in Agronomy, 2022
Dicamba injury to sensitive soybean and other broadleaf crops due to drift is a major issue. Dicamba label restrictions have been created to mitigate the off-target movement of dicamba.

Performance of Preemergence Herbicides on Waterhemp Control in Soybean [PDF]

open access: yes, 2020
The battle against waterhemp is complicated mainly because of its extended emergence period (early May until August). Preemergence (PRE) soil residual herbicides serve as a foundation for managing waterhemp, but require follow-up treatments with ...

Layered‐residual herbicide programs for waterhemp control in glufosinate‐resistant soybean

open access: yesCrop, Forage & Turfgrass Management, 2023
Core Ideas Glufosinate is an important POST herbicide for waterhemp control in glufosinate‐resistant soybean. The layered‐residual herbicide approach improved season‐long waterhemp control. Glufosinate POST combined with layered soil residual herbicides improved season‐long waterhemp control.

Managing herbicide-resistant waterhemp (Amaranthus tuberculatus) in Midwestern United States soybean systems [PDF]

open access: yes, 2023
Weed infestations, namely herbicide-resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) prevent growers from achieving optimal yields; therefore, growers are seeking tactics to reduce or prevent crop-weed competition.

Multiple Genomic Regions Govern Tolerance to Sulfentrazone in Snap Bean (Phaseolus Vulgaris L.)

open access: yesFrontiers in Agronomy, 2022
The availability of effective weed management tools against waterhemp (Amaranthus tuberculatus) is crucial to maintain profitable production of snap bean (Phaseolus vulgaris L.).

First Record of Larval Parasitism in Disonycha glabrata (F.) (Coleoptera: Chrysomelidae) by Myiopharus ancilla (Walker) (Diptera: Tachinidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The amaranth flea beetle, Disonycha glabrata (F.), is a major pest of amaranth crops (Amaranthus spp.) in the United States. Despite its economic impact, its natural enemy complex remains poorly documented. In this study, we report the first record of larval parasitism in D. glabrata by the tachinid fly Myiopharus ancilla (Walker).
