TLDR
A new premix applied before emergence (PRE) will effectively control GR horseweed at the labeled rate compared with POST applications made to ≥8 cm tall plants.Abstract:
A premix of atrazine, bicyclopyrone, mesotrione, and S-metolachlor has recently been commercialized for pre-emergence (PRE) and early post-emergence (POST) control of broadleaved and annual grass w...read more

Temperature Influences Efficacy, Absorption, and Translocation of 2,4-D or Glyphosate in Glyphosate-Resistant and Glyphosate-Susceptible Common Ragweed (Ambrosia artemisiifolia) and Giant Ragweed (Ambrosia trifida)
TL;DR: The efficacy of 2,4-D or glyphosate for common and giant ragweed control can be improved if applied at warm temperatures due to increased absorption and/or translocation compared with applications during cooler temperatures.

A Statewide Survey of Stakeholders to Assess the Problem Weeds and Weed Management Practices in Nebraska
Debalin Sarangi,Amit J. Jhala +1 more
TL;DR: Widespread occurrence of glyphosate-resistant weeds such as common waterhemp, horseweed, kochia, and Palmer amaranth were a serious problem in GR crop production and herbicide-resistant weed management in Nebraska.

Interaction of 2,4-D or Dicamba with Glufosinate for Control of Glyphosate-Resistant Giant Ragweed (Ambrosia trifida L.) in Glufosinate-Resistant Maize (Zea mays L.).
Zahoor A. Ganie,Amit J. Jhala +1 more
TL;DR: Tank-mixing glufosinate with 2,4-D or dicamba showed an additive effect and will be an additional tool with two effective modes of action for the management of GR giant ragweed in maize.

Comparison of a premix of atrazine, bicyclopyrone, mesotrione, and S-metolachlor with other preemergence herbicides for weed control and corn yield in no-tillage and reduced-tillage production systems in Nebraska, USA.

TL;DR: The efficacy of ABMS for broadleaf weed control and early-season grass weed control, and corn yield was the same or sometimes better than most of the PRE herbicides tested in this study; therefore, ABMS can be considered as an additional option for management of problem weeds, including Palmer amaranth in corn in the USA.

TL;DR: In this article, the authors proposed a multifaceted approach to mitigate the evolution of herbicide resistance by reducing selection through diversification of weed control techniques, minimizing the spread of resistance genes and genotypes via pollen or propagule dispersal, and eliminating additions of weed seed to the soil seedbank.

An evaluation of R2 as an inadequate measure for nonlinear models in pharmacological and biochemical research: a Monte Carlo approach
TL;DR: Researchers and reviewers should be aware that R2 is inappropriate when used for demonstrating the performance or validity of a certain nonlinear model and should ideally be removed from scientific literature dealing with nonlinear models or at least be supplemented with other methods such as AIC or BIC.

Evolved glyphosate-resistant weeds around the world: lessons to be learnt
TL;DR: Glyphosate-resistant weeds are a major risk for the continued success of glyphosate and transgenic glyphosate-resistant crops, however, lessons can be learnt and actions taken to achieve glyphosate sustainability.

Glyphosate-resistant horseweed from Delaware
TL;DR: Seeds originating from seed of one population collected in Delaware were grown in the greenhouse and exhibited 8- to 13-fold glyphosate resistance compared with a susceptible population, and there were no differences between the isopropylamine or diammonium salts of glyphosate.
