De nombreux acteurs &ndash; producteurs, utilisateurs de pesticides et leurs alli&eacute;s &ndash; sont attach&eacute;s &agrave; d&eacute;fendre le glyphosate &agrave; tout prix et contestent depuis longtemps les &eacute;tudes qui alertent sur sa toxicit&eacute;. Pour ce faire, ils n&rsquo;h&eacute;sitent pas &agrave; lancer, encourager voire manipuler de v&eacute;ritables pol&eacute;miques afin de prendre le contr&ocirc;le sur l&rsquo;information scientifique. Il s&rsquo;agit par-l&agrave; d&rsquo;influencer les m&eacute;dias, l&rsquo;opinion publique et les d&eacute;cideurs politiques ou de faire taire les lanceurs d&rsquo;alertes. Dans cet article, nous revenons sur plus d&rsquo;une d&eacute;cennie de pol&eacute;miques qui traduisent bien des guerres <i>par</i>, <i>pour</i> et <i>contre</i> l&rsquo;information autour du glyphosate. En nous appuyant sur des travaux pr&eacute;c&eacute;dents et des &eacute;tudes nouvelles, plusieurs cas feront l&rsquo;objet d&rsquo;une analyse sp&eacute;cifique permettant de bien comprendre le contexte agonistique et la nature des strat&eacute;gies de d&eacute;sinformation, d&rsquo;influence, de manipulation et de communication sur des sujets sensibles &agrave; l&rsquo;&oelig;uvre ici.</span></span></p> <p style="text-align:justify">&nbsp;</p> <h3 style="margin-top:3px"><span style="font-size:12pt"><span style="break-after:avoid"><span style="font-family:&quot;Calibri Light&quot;, sans-serif"><span style="color:#1f3763"><span style="font-weight:normal">Abstract</span></span></span></span></span></h3> <p style="text-align:justify"><span style="font-size:12pt"><span style="font-family:Calibri, sans-serif">Considered a probable carcinogen since 2015, glyphosate is an herbicide &ndash; the active ingredient in Monsanto&#39;s Roundup &ndash; at the heart of a long-lasting scientific controversy. Many players &ndash; producers, pesticides&rsquo; users, and their allies &ndash; are committed to defend glyphosate at all costs and have long challenged studies that alert to its toxicity. To do this, they do not hesitate to launch, encourage or even manipulate real polemics in order to take control over scientific information and thereby influence the media, public opinion and political decision-makers or to silence scientific whistleblowers. In this article we look back on more than a decade of controversies that explain numerous wars <i>by</i>, <i>for</i> and <i>against</i> information around glyphosate. Based on previous works and new studies, several cases will be the subject of a specific analysis allowing a good understanding of the agonistic context and the nature of strategies of disinformation, influence, manipulation and sensitive communication at work here.</span></span></p>
