Roundup Weed Killer Could Be Linked To Widespread Bee Deaths, Study Finds (npr.org)

An anonymous reader quotes a report from NPR: A new study [published in the Proceedings of the National Academy of Sciences] by scientists at the University of Texas at Austin posit that glyphosate -- the active ingredient in the herbicide -- destroys specialized gut bacteria in bees, leaving them more susceptible to infection and death from harmful bacteria. Researchers Nancy Moran, Erick Motta and Kasie Raymann suggest their findings are evidence that glyphosate might be contributing to colony collapse disorder, a phenomenon that has been wreaking havoc on honey bees and native bees for more than a decade. They hope their results will convince farmers, landscapers and homeowners to stop spraying glyphosate-based herbicides on flowering plants that are likely to be pollinated by bees.

"No large-scale study has ever found a link between glyphosate and honey bee health issues," Bayer said in a statement, adding that the new study "does not change that." Bayer noted the study relied on a small sample of individual bees and that it does not meet regulatory research criteria on pesticides stipulated by international guidelines developed by the Organization of Economic Cooperation and Development and other international organizations. Additionally, the company suggested it is "questionable whether the concentrations of the substance tested could at all be absorbed by bee populations in the open over a relevant period of time." According to the report in the journal, the researchers focused on honey bees and used "hundreds of adult worker bees from a single hive" and treated them with varying levels of glyphosate.
Editor's note: In June, Germany's pharmaceutical giant Bayer purchased Monsanto, the company that developed Roundup.

    I know we are not supposed to kill wasps, as they are pollinators and help to control insects

    Actually, most wasps in North America - especially more northern states - are not pollinators. They are predators but they don't pollinate anything. And being as they are not limited in their ability to sting (as most bees are) they can be a much more significant threat to humans. In other words, fire away. Get the wasp killer from your local big-box store and go to town. Generally the sites where wasps (especially the exceptionally common paper wasp) build their nests are not attractive nesting sites for any kind of bee, so the collateral damage is generally pretty low.

    The exception to the non-pollinating wasps are the wasps that pollinate figs (this is actually why figs are never vegetarian - you can't eat a fig without eating wasp eggs). If you live someplace where figs cannot grow, there is almost no chance that the wasps in your area pollinate anything.

    It doesn't necessarily follow.

    I know more about mosquito control, since I worked in that industry for decades, but in that field the common pesticides are chosen because they have low toxicity for non-target species and low potential for bioaccumulation because once deployed in the environment they break down rapidly into non-toxic byproducts. I assume that herbicides are approved using similar criteria.

    Now herbicides are targeted at the plant kingdoom, and bees are in the animal kingdom. Glycophosphate in particular targets a metabolic pathway that is found in plants and fungi, but not animals. That tells you exactly zero about whether it's harmless to animals; it might kill animals in a completely different way. You have to conduct tests.

    Tests show that glycophosphates have a high LD50 (i.e., low toxicity) for animals, but that's acute toxicity. It takes a lot of Roundup to kill an animal outright, but that doesn't mean it can't affect the animals behavior and reproduction in ecologically disruptive ways. If you exposed all humans to a drug which was harmless but made men impotent, human populations would crash even if the drug had an infinitely high LD50.

    If this sounds complicated, that's because it is. But that's no reason to throw our hands up in the air and assume everything will be OK. At this point nobody's in any position to state anything definitive about the impact of glycophosphates on bees; this study has successfully opened a question we don't have an answer for yet. But if we study this problem, we'll get a definitive answer. Either way some people might not like that answer, but at least it's a rational basis for making policy.

    This headline and the comments it has created have me scratching my head. I and other farmers use a fair amount of glyphosate but I can't think of any time I'v seen it used on flowering plants. Glyphosate use is fairly staggering in quantity but nearly all of that is used on glyphosate-resistant crops to control weeds, and this by definition must be done when the crop and weeds are very small. In other words, weeks or months before flowering. If glyphosate were sprayed on a crop that was flowering it would abort flowers and destroy yield, if not making the plants very sick. So it wouldn't make any sense for a farmer to use glyphosate in this way to begin with. Something smells funny.

    By the way we also have our own bees that we use for pollinating a glyphosate-tolerant crop.

    In yards and around homes also, glyphosate is typically not sprayed on glowering plants. Why would it be? You wouldn't use glyphosate to remove dandelions from your lawn for example (if you do, you're in for a very dead lawn).

    This study is highly problematic for this reason. The findings may well be true about toxicity to bees, but if glyphosate isn't used typically on flowering plants or weeds, then the study is somewhat pointless, if interesting. Certainly it cannot inform any policies over the use of glyphosate, except to urge that it not be used on flowering plants, which it already isn't.

    In the end, however, those calling for the end of glyphosate will probably get their wish as over-use of glyphosate is rapidly ending the effectiveness of that chemical. And everyone will end up paying for that in increased food costs.

The data actually argues that we should give bees more glyphosphate in order to neutralize any effects.

What they wrote is literally the equivalent of writing re. humans "If you take some antibiotics that kill only a fraction of your gut bacteria, you're going to wander off in confusion and die".

Bees are not going to have any interest whatsoever hanging around a field that's been sprayed with glyphosphate. Glyphosphate also does not stay on the surface; it's highly soluble and washes into the soil, where it binds tightly with soil particles.

    But of course, the study said something negative about glyphosphate, so of course everyone covered it, in as apocalyptic terms as possible.
