A previously elaborated capillary electrophoresis (CE) method used for the determination of glyphosate and aminomethylphosphonic acid (AMPA) was slightly modified in order to improve the sensitivity. However, detection limits attained (5 μg mL −1 for glyphosate and 4 μg mL −1 for AMPA) were still not satisfactory for analytical purposes, thus the a...

Les pesticides ionisables sont des composés polaires très solubles dans l'eau. Les méthodes conventionnelles d'extraction sont par conséquent peu adaptées à l'analyse en routine de ces composés au niveau réglementaire de 0,1 æg/l. Nous avons choisi une stratégie d'analyse in situ dans l'échantillon, en nous fondant sur l'expérience acquise pour l'a...

An uncertainty budget is presented for the results of measurements of purity of the agrochemical glyphosate using 1H and 31P quantitative nuclear magnetic resonance (QNMR) spectroscopy. The budget combines intralaboratory precision from repeated independent measurements of a batch, and other Type A and Type B effects. Consideration of correlation o...

Glyphosate is a non-selective broad-spectrum herbicide that inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), a key enzyme in the aromatic amino acid biosynthetic pathway in microorganisms and plants. We have previously reported a strategy for engineering glyphosate-resistant class I EPSPS based on staggered-PCR technology. Selected mut...

The term ‘biopesticide’ encompasses a broad array of microbial pesticides, biochemicals derived from micro-organisms and other natural sources, and processes involving the genetic incorporation of DNA into agricultural commodities that confer protection against pest damage (plant-incorporated protectants). Some microbial pesticides, such as Bacillu...
