Has anyone bothered to record which formulation of glyphosate is being anecdotally reported as killing bees?
i.e. What salt? Potassium, isopropylamine, monoammonium etc.
I doubt it, it would also be nice to confirm that it was in fact glyphosate. Plenty of people just assume that is a farmer is spraying then it has to be roundup that is being used.
There are hundreds if not thousands of chemicals used around farms and the majority are known and have been shown to be more harmful to bees than glyphosate yet people seem to want to blame it for anything and everything.
In Aus at least if you see a farmer spraying you can bee 99% sure that what is being applied isn't straight roundup. At the very least it will almost certainly being applied along with a surfactant. Add a surfactant to water and spray bees and in ideal conditions there is a very good chance you will kill bees. The surfactant doesn't kill them the water does because they are properly wet.
Glyphosate is often applied along with other herbicides and pesticides, they are mixed and applied in the one application, chances are the other chemical being applied at the same time are more harmful to bees and a combination of chemicals can be harmful even when individually applied they are not.
I'm sorry but I don't buy the anecdotal reports of glyphosate killing bees, sure bees dying after spraying maybe even after spraying with glyphosate but I would be 99.99% certain they haven't died from glyphosate poisoning.
