Bioaffinity-based Concept for Glyphosate Detection
… between acetylcholinesterase (AChE) and glyphosate, specifically its potential suppression. The study optimizes parameters such as pH levels, enzyme concentrations, and substrate concentrations using the Ellman enzymatic assay. AChE activity is best maintained at 50 mU with 3 mM DTNB and …

Glyphosate Resistance in Plant Cell Cultures
… in order to identify the mechanism underlying glyphosate resistance. Uptake experiments, using radiolabelled glyphosate, showed higher or similar absorption levels in the resistant lines compared to the unselected control. Such results exclude uptake as a mechanism of glyphosate resistance. …

Weed resistance risk management in glyphosate-resistant cotton
The introduction of glyphosate resistance into Australian cotton systems will have an effect on conventional weed management practices, the weed species present and the risk of glyphosate resistance evolving in weed species. Therefore, it is important that the effects of these management practices, …

Sorption and leaching of glyphosate on partly sealed urban areas
Anlass für die Untersuchungen war der Einsatz des Herbizids Glyphosat zur Unkrautbekämpfung auf Gehwegen. Da das für den Gehwegbau eingesetzte Material, geringere Sorptionskapazitäten für Glyphosat als landwirtschaftliche Böden aufweist, war das Ziel dieser Arbeit abzuschätzen, ob nach Applikation …

Composite poly(dimethoxyaniline) electrochemical nanobiosensor for glufosinate and glyphosate herbicides
… determination of the herbicides glufosinate, glyphosate and its metabolite aminomethylphosphonic acid (AMPA). Firstly, the nanostructured poly(2,5-dimethoxyaniline) (PDMA) materials were synthesized on gold electrode by the electrochemical "template"method using poly(4-styrenesulfonic acid) …

Bioavailability of metolachlor and glyphosate in aerobic and anaerobic soils
Metolachlor and glyphosate are two extensively used herbicides in the USA and throughout the globe. Despite the prevalence of anaerobic wet situations in the soil, the predictive capability for the environmental fate and bioavailability of these herbicides is based primarily on well-drained soil …

Regional whole plant and molecular response of Kochia scoparia to glyphosate
Globally, glyphosate (Roundup®) resistant weeds pose a serious challenge to modern agricultural practices that utilize glyphosate for weed control, including Roundup Ready® cropping regimes. Locally, glyphosate resistant Kochia scoparia have been identified throughout the central Great Plains, and …

Response of Grapes to 2,4-D, Dicamba, and Glyphosate Simulated Drift
… modified crops such as Roundup Ready® (glyphosate-resistant) corn and soybean, herbicides that normally would have killed a crop can be used for weed control. Over years of use, some weed species have developed resistance to glyphosate and require novel approaches to management. New …

Alternative Herbicide Control Options for Glyphosate-Resistant Palmer Amaranth (Amaranthus Palmeri)
<p>The occurrence of glyphosate-resistant (GR) Palmer amaranth has prompted a shift in weed management strategies worldwide. Studies were conducted with the aim to (1) establish and compare the degree of tolerance of GR Palmer amaranth populations; (2) assess the efficacy of glufosinate, …

Activity Enhancement and the Mechanism of Glyphosate Action in Common Cocklebur
… tips were used to investigate the mechanism of glyphosate {N-(phosphonomethyl)glycine} action. The incorporation but not the uptake of ('14)C-leucine was significantly decreased by 2 h after treatment. The incorporation declined steadily over a 32 h time course. The uptake of ('33)P by the roots …

Comparative studies on the modes of action of SC-0224 and glyphosate
… carboxymethylaminomethylphosphonate) and glyphosate [N-(phosphonomethyl)glycine] (PMG) were compared. In each study trimethylsulfonium iodide (TMS-I) was included as a treatment because the trimethylsulfonium ion is a constituent of the SC-0224 molecular structure. In inflated duckweed …

Conyza bonariensis glyphosate tolerance as affected by origin temperature and growth stage
Glyphosate was patented as a broad-spectrum, non-selective, systemic herbicide in 1974. In 1996, glyphosate-resistant Lolium rigidum (rigid ryegrass) was reported in Australia. Since then 34 other weeds the world over have evolved resistance to this herbicide. The first case of glyphosate …

Differential Response of a Virginia Common Lambsquarters (Chenopodium album) Collection to Glyphosate
… which exhibited a differential response to glyphosate treatments as compared to most other common lambsquarters. Plants from this site that survived glyphosate applications were collected in both 2002 and 2004. Greenhouse studies were conducted on F1, F2, and F3 progeny from this collection …

Development of plasmonic sensor using gold nanobipyramids for detection of glyphosate based pesticide
… (GNBPs) as sensing material for detection of glyphosate based pesticide (GBP) has been performed. The GNBPs was synthesised using seed-mediated growth method (SMGM). In the synthesis process, the effect of three different additive acid types which are chloric, sulfuric, and fluoric acid, and …

Examination of target-site-based mechanisms of glyphosate resistance in waterhemp (Amaranthus tuberculatus)
Glyphosate is one of the most important and widely used herbicide in the world. While few weed species had evolved resistance in the two decades after glyphosate’s commercialization in 1974, an overreliance on glyphosate and lack of diversity in weed control methods following the introduction of …
