Supreme Court Hears Case On How To Label Risks of Popular Weed Killer (npr.org) 74

An anonymous reader quotes a report from NPR: A divided U.S. Supreme Court on Monday heard a dispute over labels on the popular Roundup weed killer, which thousands of people blame for their cancers. How the Supreme Court rules could have implications for tens of thousands of lawsuits against Roundup maker Monsanto, which is now owned by Bayer. The case centers on who decides about warning labels on chemicals: the federal government -- or states or juries. [...] The justices will not be evaluating whether glyphosate causes cancer. Rather, they'll consider who should decide what appears on warning labels and whether states have a role to play after the EPA weighs in.

The current U.S. solicitor general backed Monsanto. Sarah Harris, his principal deputy, said the Environmental Protection Agency is in the driver's seat, not anyone in Missouri. "Missouri thus requires adding cancer warnings but federal law requires EPA to approve new warnings and tasks EPA with deciding what label changes would mitigate any health risks," Harris argued. "State law must give way." Several justices, including Brett Kavanaugh, appeared to agree with Monsanto's argument about the need for a single, uniform standard across the country.

But others, like Chief Justice John Roberts, wondered what would happen if the federal government moved more slowly than states did, who wanted to act quickly on information about new dangers. "Well, it does undermine the uniformity," Roberts said. "On the other hand, if it turns out they were right, it might have been good if they had an opportunity to do something, to call this danger to the attention of people while the federal government was going through its process," he said about states.

Justice Ketanji Brown Jackson asked about the emergence of new science, and the EPA's reviews. "There's a 15-year window between when that product has to be re-registered again and lots of things can happen in science, in terms of development about the product," she said. Bayer, which now owns Monsanto, only sells Roundup that contains glyphosate to farmers and businesses these days. Bayer has been pushing to resolve scores of the residential cases through a sweeping settlement, trying to put the costly claims behind it.

    When robots with lasers can selectively kill weeds and bugs, the need for herbicides and insecticides will disappear

    • We have robots which can do that, but they will not be cheaper than glyphosate for the foreseeable future, so they won't be used. And any time soon, they will be MASSIVELY more expensive, so it's not realistic that they will be mandated any time soon either.

      • Glyphosate is cheap enough, but are the resistant seeds?

          Weed-zapping robots are still very expensive, so yes, still cheaper.

          Another question we could ask would be whether the total cost including ecological impact is less, but then we'd get into a debate which is unfortunately irrelevant to farmers who are trying to make a profit year on year.

      I know that we're all nerds but you can't technology yourself out of human interaction. Human beings are still human beings and do human being things.

      Technology can help and sometimes because human beings suck so much we just have to hope it saves us.

      The problem with relying on it exclusively is that there's no guarantee we're going to get the technology we need fast enough and good enough to keep Pace with human beings doing bad things.

        It's probably better not to fire lasers at the explosive trees.

        Fun story, one time when I was a kid I came across some eucalyptus trees which someone had planted along a ravine and, as a good citizen, I chopped them the fuck down with a wooden stake. Well it turns out that the people who planted them saw me do it and complained. At the time I was living in a trailer park, and the person they complained to was the park manager. Well, the place they had planted those trees was on a neighboring property and wh

    • We have that today. The Carbon Robotics LaserWeeder G2 is a product you can buy right now for $1.2 million. But it requires significantly more effort to use and more frequent application than throwing roundup at the problem. Also with roundup only costing the average US farm $25000 per field application, and the average EU farm $2000 per field application, paying $1.2million is a difficult pill to swallow.

      • by flink ( 18449 )

        Does the average farmer need to own one? I imagine it must sit idle a lot of the time unless constantly in use. Could a regional services company own a few and process fields on a pay per use basis and spread the capital cost around?

        • by caseih ( 160668 )

          Possibly, much like how many small farms hire out herbicide application. The biggest issue is that the electric weeder is slow and requires multiple passes. And all farmers require weed control about at the same time. But one benefit to the electric weeder is, depending on the crop, it could be applied much later in the season to control late flushes of weeds. Herbicides will injure crops that are past a certain stage of growth. The later in the season, the more risky it is to apply herbicides.

      • by caseih ( 160668 )

        Not quite sure where your numbers come from. Glyphosate is typically between $5 and $6 CAD a litre, and a applications are anywhere from 0.3 to 0.7 l/ac (messed up units, yes i know but that's what we use). So chemical cost is extremely low, $2 to $4 per acre not counting labor and fuel. Application is extremely fast, more than 100 acres per hour.

        The electric weeder is expensive, slow and costly to operate currently. But I'm hopeful this will improve. You're right it's a prohibitively expensive pill to

  • How will this affect all the companies that just go ahead and slap California Proposition 65 labels on everything? To prophylactically prevent prosecution there?

    If the US Supreme Court is going to attempt bringing everyone in line to follow uniform regulations and eliminate Cali's interference with the Commerce Clause, they really have their work cut out for them. It is a noble undertaking to be sure, but I fear a bit too late.

    I'm a medicinal chemist and have been for 45 years. I also tend to vote fairly liberally, though the leftists thought police were beginning to get on my nerves. Anyhow, my feeling is that glyphosate is probably a lot safer than anything that we try to replace it with, that works as well. When anything has been used as much a glyphosate and the only people sure of it's toxicity are lawyers, then you've got a pretty safe agent. Go to Lowe's hardware and get a container of new Roundup and read the label. The new stuff in there is surely more toxic than glyphosate and is more chemically kin to Agent Orange and paraquat. Be careful what you ask for here. Oh yeah, I kind of feel the same way about methylene chloride.

      The intelligent thing to replace it with is zero-tilth regenerative agriculture, which doesn't require weed killer.

      Glyphosate is underlabeled thanks to lots of money applied to government by Monsanto, still the world's largest producer of it.

    • Anyhow, my feeling is that glyphosate is probably a lot safer than anything that we try to replace it with, that works as well.

      Safer than mechanical alternatives? You can buy an automated laser-weed-killer today. A product that doesn't cause cancer for farmers and has no chemical interaction with their product. So I question where you get your ideas from since the use of chemicals is objectively less safer than the use of no chemicals, even without the guesswork.

        Walks out to shed and grabs Roundup Brush Killer concentrate purchased at Lowe's last week... looks like the label claims active ingredients of triclopyr triethylamine salt 2.5%, fluazifop-P-butyl 2.0%, diquat dibromide 1.5%. That's what I purchased here in the Bay Area; interestingly enough Home Depot doesn't carry the brush killer and claims it is not available in California but I've always been able to purchase it at Lowe's.

          As a farmer who uses pesticides it boggles my mind that Bayer is selling diquat to consumers! Diquat is a lot more toxic than glyphosate (but a lot safer than paraquat).

          But diquat is safer to use it around trees as it won't kill them. It's a contact chemical that burns leaves (quickly). It's not translocated into the plant's roots, so if the roots continue to grow it won't kill the plant. If defoliating the poison oak will kill it, then diquat will work well. Be sure to wear PPE and don't let it on your s

          • Ironically, given Bayer is a European country, Roundup does not contain diquat dibromide in the EU. That was banned 6 years ago.

        • I'd love to use goats but they are really quite expensive.

          Have you considered using sheep instead? I've read about them being used, but I don't know how expensive they are. And, if you do use goats, be careful about using them near fruit trees if you plan on harvesting the fruit because goats are very good tree climbers. As an example, I once ran across a short video of a goat working its way up a palm tree to get at the dates, so regular trees wouldn't be a bit of difficulty.
        • Indeed your "Roundup" (which is a brand covering a group of products, not a specific product) does not contain Glyphosate isopropylamine salt at 18% which is what is strongly linked to farmers getting lymphoma. Residential products replaced it with triclopyr triethylamine salt, and let's face it, they don't work as well.

      • Which formulations? That it matters at all suggests glyphosate wasn't the problem, but the other stuff in the formula.

        And do you think that not selling it to consumers is because of health risks or because of legal risks, like being sued?

        • by caseih ( 160668 )

          Definitely adjuvants and surfactants are a big health unknown. Glyphosate itself seems quite safe. Three generations of farmers have used it and have been exposed in far higher amounts than many of these sick people blaming their cancer on glyphosate. But although pesticide active ingredients are highly regulated and tested for safety, adjuvants and surfactants are not. Many of them contain organic solvents that could be carcinogenic. Manufacturers need not tell you anything about their formulation. It

        • That it matters at all suggests glyphosate wasn't the problem, but the other stuff in the formula.

          Literally glyphosate was what was removed from what you get on the shelf. Go down to Lowes right now and check the ingredients list, the main active ingredient is triclopyr triethylamine. Bayer hasn't sold roundup containing glyphosate to consumers in the US for 4 years now.

          And do you think that not selling it to consumers is because of health risks or because of legal risks, like being sued?

          Now why would someone sue? Because the feel like losing money to a mega corporation worth 35billion EUR? If you're concerned about getting sued it's because you're concerned about the suit being valid.

        Acetylene torch works too. Problem is it doesn't kill the roots, so the weeds come back.

  • Montesano wrote the studies, and the most cited study by the EPA and other departments, that found that the chemical didn't cause any cancer.

    Meanwhile, studies by labs not linked to Montesano found that the chemical was a probable cause of cancers.

    This is what isn't being discussed in this Supreme Court case. Whether or not the label is accurate, and it is. Sad that they get caught up in the procedural, and on the company side rather than with science, and on the consumer side.
