Diquat is banned in the UK, EU, China and other countries. The US has resisted calls to regulate it

The herbicide ingredient used to replace glyphosate in Roundup and other weedkiller products can kill gut bacteria and damage organs in multiple ways, new research shows.

The ingredient, diquat, is widely employed in the US as a weedkiller in vineyards and orchards, and is increasingly sprayed elsewhere as the use of controversial herbicide substances such as glyphosate and paraquat drops in the US.

But the new piece of data suggests diquat is more toxic than glyphosate, and the substance is banned over its risks in the UK, EU, China and many other countries. Still, the EPA has resisted calls for a ban, and Roundup formulas with the ingredient hit the shelves last year.

    also some weeds are becoming resistant to glyphospate, they will have to keep using ever increasing toxic herbicide to combat it.

      This. The only thing outside of oil we can export in mass is our agricultural products. But years of disinformation and corporations greed even our dirt is infected with their taint.

          Culture… Whenever I go over seas I’m actually surprised how fast US culture is disappearing. Movies, music, and such was something we held a strong monopoly on. But but that’s only because we’re the most technically advanced to mass produce such things. Now. Nearly every other nation especially China’s and Russia’s “Hollywood” pumps out enough content to satisfy their demographics. American (western) content used to be the only thing on the shelves over seas. Now we’re relegated to just a corner. The world doesn’t care as much about our pop music and movies. Those have greatly decreased in quality anyways.

    Notice Canada is not listed as a country that bans diquat. It is legal and available here.

    The largest billboard on my way to work says stop punishing farmers–don’t ban glysophate. I’ve been complaining about the toxic state of the missouri river since highschool. People don’t care. For killing weeds on gravel, dillute some white vinegar and add dish soap to kill weeds. It’s a cost effective and environmentally friendly weed killer. That, and blocking light with cardboard.

    The trolls will be here claiming that it isn’t proven in 3…2…1…

    The research further scrutinizes how the substance harms the kidneys, lungs and liver. Diquat “causes irreversible structural and functional damage to the kidneys” because it can destroy kidney cells’ membranes and interfere with cell signals. The effects on the liver are similar, and the ingredient causes the production of proteins that inflame the organ.

    Meanwhile, it seems to attack the lungs by triggering inflammation that damages the organ’s tissue. More broadly, the inflammation caused by diquat may cause multiple organ dysfunction syndrome, a scenario in which organ systems begin to fail.

    Sounds like secretary brainworm will be all over this before you can say brainworm. This is the kind of thing that is right up his alley. Harmful chemicals in our food supply? He is so against that, and will certainly do something for this very very very soon. I have complete faith.

    Ah shit the grass killer I have has diquat. But the weed killer variant from the same brand doesn’t have it, which is interesting.

      Just don’t get it in your body and you’ll be fine. (This includes eating foods sprayed with it without washing. Maybe also foods grown in contaminated soil; I didn’t read the article or study thoroughly.)

      Personally I use Natria weed killer (https://www.tractorsupply.com/tsc/product/natria-grass-weed-control-with-root-killer-1-gal-707201a), active ingredients: Ammoniated soap of fatty acids, Maleic Hydrazide. I still wouldn’t get it in your body, but I’m pretty sure it’s less harmful and breaks down into harmless components much quicker.

      Of course it’s also less effective, so it might take multiple applications, but that’s to be expected.

        The problem is all that ends up in the groundwater. Obviously industrial use is the problem, but I think it is responsible to avoid any herbicide especially if it is just to make your yard “look nice”.

        Diquat bonds strongly to mineral and organic particles in soil and water, where it remains without significant degradation for years. However, bound to clays, diquat is biologically inactive at the concentrations typically observed in agricultural soils.

        Unfortunately, the “just don’t eat it” idea doesn’t work so well when it persists in the environment for so long

          I would, but that doesn’t work for stuff coming up through cracks in concrete, or through chain link fence. Most of the stuff I spray is stuff I can’t pull.

          I had some oriental bittersweet coming up, and for that I dug down and pulled as much as I can, didn’t even bother spraying. But there’s also Virginia creeper and black swallow-wort around here mixed in with other stuff, including on the property line that I can’t physically reach to pull. So that stuff I spray. (The neighbors basically let it grow wild, so they dgaf, I just keep it minimal.)

            For that sort of stuff, I recommend vinegar or propane. lMO the only reason to use a fancy commercial herbicide is when you need it to be selective, e.g. when you’re trying to get rid of broad leaf lawn weeds without killing the grass, too. (Edit: I’m not endorsing that as a good reason, BTW, as I’m more of a [email protected] sympathizer myself. I’m just saying that it’s the only one that’s even plausible.)

    So the only thing that I haven’t been able to figure out - is the danger from glyphosphate and now diquat the vapor after spraying or consumption of plants in close proximity?

      I think the study alludes more to consumption of stuff exposed to it in agriculture. But I am interested as well because the grass killer I use at home has diquat, and while I wear shades and a mask when spraying, I can still smell a hint of it.

    This is what happens when you vilify the safest weed killer ever discovered because “chemicals are bad”.

    Not to mention that the kind of anti-scientific hysteria around glyphosate led directly to Robert Kennedy Junior.

      No, this is what happens when you (a) have a “allowed until proven unsafe” regulatory framework instead of a “prohibited until proven safe” one, and perhaps more importantly (b) abjectly refuse to consider any weed control method other than ones that can be accomplished by indiscriminate use of a sprayer.

        If your proscriptions were adopted, at least 4 billion people would starve and/or die from disease.

        Kennedy doesn’t care.

          Stop growing fucking soy, canola and corn for fuel and plastic and it’s easy to feed everyone. It’s not about feeding people it’s about money.
