We have just published a rebuttal to a recent debate article on „the cocktail effect“ that Martin Larsson (toxicologist from Bayer Crop Sciences in Denmark) published in Svenska Dagblad a couple of days back. In case you are also struggling with SvD’s anti-adblocking mechanism and/or with them pressurizing you to make you pay for viewing…
I’ve gotten involved in quite a few glyphosate debates recently, in very different contexts (online, with colleagues, regulators, industry representatives, friends, etc.). It’s certainly an interesting and relevant subject. But I wonder why the discussions derail so often. Some thoughts below. A debate can of course be held just pro forma, in order to represent…
In the wake of the recent glyphosate discussion, it became clear that there are some misconceptions on what „Maximum Residue Levels“ (MRLs) for pesticides actually are, and whether or not they have any toxicological basis (see comments to this post). So, here’s a brief overview. Europe In Europe, the setting of MRLs is regulated by…
Michael Clark and David Tilman recently compared organic and conventional agriculture (Clark & Tilman, 2017). The analysis was taken up and republished by „Our World in Data“ in a post titled „Is organic really better for the environment than conventional agriculture?“ However, both, the paper and the blog-post, miss a major point, perhaps the major…
The discussion on Glyphosate & RoundUp (or other Glyphosate containing pesticide products) on Twitter continues. A quite interesting one, actually. I would like to take the opportunity to reply to a few comments made. I’m aware that it is a bit unfair to use the space provided by a blog to answer comments and critique…
I have recently complained about the use of LD50 values (the amount of a compound that kills half the exposed organisms after a short exposure) to compare and rank the toxicity of glyphosate. Maybe it’s pure coincidence, or maybe I just wanted to avoid some of the manuscripts waiting for me. But I came across…
For some reason, I recently managed to get into a discussion on glyphosate (the active ingredient of Roundup and other herbicidal products) on twitter. 140 characters might be sufficient for exchanging quick comments (and, obviously, for discussing US politics). But they are certainly not sufficient for exchanging any real arguments. So, here’s the story and…
Ok, after deleting all old posts, let’s start with a blank slate… The major content has been moved to the different sections of the site (see the entries in the menu above). Thomas
