I've been using strong vinegar for weed control on my property for a few years now. You do have to be careful about applying it and watch the over-spray because it is not a targeted herbicide like Roundup, it's going to kill grass and broadleaf plants alike. Sometimes I lay down a tarp to mask off the grass border, for example. But if you have a general weedy area that just needs to be knocked down, or a gravel path/driveway to keep clear, I have found it is just as effective, quick-acting, and long-lasting as the synthetic herbicides, with the side effect of smelling like salad dressing, instead of smelling like cancer.

I buy 30-45% concentrate depending on what is on sale, and dilute to around 10% for new weeds and 20% for full grown weeds. A little dish soap in there helps it wet down the leaves. For lawn weeds, once they are under control, I've been able to keep up with a 1/4 acre lawn with just manual weeding. Good tools help, I have tried a lot of weed pulling gadgets. Using a push mower means I go slow enough to spot them, and if they get too big they jam the mower so I am motivated to pull them while they are still small.

    I've used the same, and it seems just as, if not more, effective than the roundup available from the garden centre.

    The only problem is that vinegar destroys spray machines. Even though I rinse through after every use.

My long-departed grandmother lived her entire life in Grodno, a city in western Belarus on Nieman river. It is a lovely and fertile region with well defined seasons of the year. All kinds of things grow there, mostly temperate weather crops, potatoes, tomatoes, peas, cucumbers, carrots, radishes, cabbages, apples, pears etc. Grandmother was a big believer in child labor so my summer was spent weeding every day. Her herbicide/pesticide were little children hands. I think vinegar was involved too. I think though if she could afford chemicals she would have. Ugh, if I never have to squish colorado potato beetle larvae from the potato leaf, I'll be happy.

I have an acre of forest and I spend time removing invasive species like buckthorn and wild mustard to keep the forest healthy. It can be really challenging to discriminate between native and invasive plants without a lot of experience and plant identifying apps like iNaturalist. I would love to be able to sweep my phone around and have it highlight invasive plants live. Is anyone working on something like this? The technology already works in images of a single plant, I just need to identify multiple plants in one frame, and ideally live video.

Wondering whether glyphosate-resistant plants will keep their resistance after glyphosate is no longer being used. Will that vestigial trait become a liability due to some extra energy costs, and eventually fall back out of the gene pool?

  • bell-cot 36 minutes ago

    Yes - eventually. The selective pressure to acquire resistance to a widely used herbicide is enormous. The "takes tiny a bit more energy" pressure to lose a useless trait is minimal.

Weeds have a function which does run opposite to the objectives of monoculture, but I'd probably put my money on millions of years of evolution over the needs of industrial farmers. Permaculture and "food forest" methodologies are not as good for anyone's profit margin, but they are more resilient and lean on natural processes of ecological niche development instead of fighting them.

The weeds discussed in this article, Amaranthus tuberculatus and Amaranthus palmeri, are exactly the kind of plants that early human cultivators would have selected as a seed crop - fast-growing robust plants that could be continually selected for maximal seed size and minimal toxin production generation after generation (which is how crops like maize were developed). Indeed members of this genus were used by Aztecs and others for just that purpose:

As far as maintaining fields, area spraying of pesticides and herbicides will be replaced with robots wielding lasers and using AI image recognition to catch pest infestations before they take over entire fields.

  • fuzztester an hour ago

    Some Amaranthus species are used in India too, as foods. The grains are used to make laddus (sweet balls made by mixing the grains which sugar or jaggery) and the leaves are eaten as cooked greens with spices, masala, onions, etc. Both are quite tasty.

      Aside from these not currently existing, they also have far worse failure modes than robots with lasers. Introducing species for biological control methods have a long and storied history of becoming a problem as bad as or worse than the original problem.

> Monsanto claimed it was “highly unlikely” that glyphosate-resistant weeds would become a problem. There were, of course, those who correctly predicted that such a thing was inevitable

I've started noticing that this happens all the time, across all fields. Experts disagree, the expert with the most positive outlook is the one whose opinion wins out, and we find ourselves in trouble years/decades later.

I've adopted a "treat every expert as a lawyer" mindset now that has helped illuminate some of this for me. I prefer to listen to podcasts where people in the field talk to each other, rather than someone presenting the information to the layperson. There's a lot of jargon but you can very easily get a sense of (1) what issues does everyone agree on (2) what issues are they bickering on, and what their reasons are

  • cyberax 3 hours ago

    The emergence of resistance to glyphosate was a given. Monsanto itself sells glyphosate-resistant plants, so we know exactly how it can evolve.

    The resistant gene was isolated from an Agrobacterium strain. And these bacteria have been doing gene editing in plants for hundreds of millions of years, completely naturally. So it was just a matter of time until weeds gained the resistant genes from it. Or evolved them via a different mechanism.

    Still, glyphosate bought us at least six decades of relatively weed-free agriculture for staple crops. Resistance is still not universal, so glyphosate will continue working for a while, helping to lower the price of food.

      • analog31 3 hours ago

        Devil's advocate: I've asked a couple of farmers about this. The conventional wisdom is that glyphosate reduced the carbon footprint of farming.

          • adrian_b 2 hours ago

            Despite the very large recent decreases in the price of lab-grown meat (I have just seen an announce about a company that claims that they "can now produce 100 percent cultivated chicken (85 percent muscle and 15 percent fat) at $11.79 per pound on a large scale"), it is not yet proven that lab-grown meat can be produced at a lower price and by consuming less resources than traditional meat.

            On the other hand, it is pretty certain that it is possible to produce high-quality animal proteins, like whey protein or egg white protein, in a sustainable way and at a lower cost, by cultures of genetically-modified fungi, which can be fed with cheap carbohydrates from cereals and with minerals, unlike the animal cells which require a very complex food.

            The company that has achieved the low price quoted above has done this by replacing the animal food that was given previously by everybody to the cultivated cells (e.g. serum and albumin) with some mixture of substances extracted from various vegetables.

            It is unlikely that it will be ever possible for the food given to cell cultures to be cheaper than the food given to real chicken. The only chance for lab-grown meat to become cheaper than real chicken meat is given by the fact that only the edible part of a chicken is grown, i.e. the equivalent of a breast or thigh, instead of growing the entire chicken body with many parts that have a low value.

            While fungal cultures would be much more efficient than any lab-grown meat, they could provide only protein powder, which could enrich in proteins any vegetable food, but from which it would not be easy to make something resembling a steak.

          • tmitchel2 2 hours ago

            Could you pinpoint what exactly is not sustainable about eating meet though? In the UK (where I live) we eat meet produced mostly within the country, the livestock here are generally mostly fed a grass diet. Yes we should eat meet in moderation like anything, yes chopping down rainforests and building feeding lots is obvs horrific. But otherwise, the cattle eat the grass, they turn that into meet and farts, which fairly quickly come full circle back into the ground. No fossil fuels here. Hard to think of something more sustainable to me.

          • analog31 3 hours ago

            Indeed, our current dietary "normalcy" is an engineered phenomenon to begin with, and a new one can be engineered just as well.

          • mrguyorama 2 hours ago

            Lab grown meat is an economical dead end. Way too many large scale meat eaters in the US think it's fucking identity politics somehow, and will willingly pay more for "real" meat even if lab grown meat could magically become cheaper, which it has shown no ability to so far.

            The people like me, willing to eat lab grown meat, already are willing to pay more for more carefully grown meat and just eat less meat in general. We are the minority.

            The fake meat industry is currently failing. Probably because their products were hyper processed trash that was usually less palatable than a comparable meat replacement, not healthier in general, and somehow STILL more expensive than real meat.

          The EPA says that glyphosate isn't carcinogenic in humans. The WHO says that it is.

          The EPA says it's not an endocrine disruptor. Numerous studies and experts suggest that it is, although I can't find any major government or NGO that agrees.

          I'm not a doctor or molecular biologist. How should I decide which experts to trust? I can easily afford food grown without glyphosate, so that's what I eat.

          EDIT: I'm not religious about this, presumably all the restaurant food I eat is grown with glyphosate. But my local grocery store only has organic produce, I usually buy that since it's convenient and the cost difference is not a big deal.

          • nonameiguess 2 hours ago

            You're presumably thinking of the IARC monograph. You can read how the classifications work in their own preamble: https://monographs.iarc.who.int/wp-content/uploads/2019/07/P...

            Specifically,

            > A cancer hazard is an agent that is capable of causing cancer, whereas a cancer risk is an estimate of the probability that cancer will occur given some level of exposure to a cancer hazard. The Monographs assess the strength of evidence that an agent is a cancer hazard. The distinction between hazard and risk is fundamental.

            > The identification of a cancer hazard should trigger some action to protect public health, either directly as a result of the hazard identification or through the conduct of a risk assessment.

            The key thing to recognize here is they are making preliminary assessments of existing lines of research, looking for studies into whether an agent has been associated with cancer in humans, animals, or mechanistically, and characterizing the strength of such evidence, as to whether or not something can cause cancer.

            The purpose of doing this is so that other standards bodies can assess the actual dose/response relationship and your probability of getting cancer from levels of exposure. Glyphosate in in group 2A, along with things like being a barber, night shift work, hot beverages, red meat. Lots of things the EPA does not ban.

            Why? Because as the organization itself says, hazard does not mean risk. The fact that studies show a robust association between one thing and some increase in cancer incidence, at any dose, does not mean the level of exposure any regular person experiences raises their probability of getting cancer by any meaningful amount we should care about or regulate.

            The problem here is you're almost certainly not actually reading the publications of either IARC or the EPA, which are not in conflict with each other. You're reading science journalism, which almost universally presents this in the most misleading, fear-mongering fashion possible to attract eyeballs.

            • hollerith 2 hours ago

              The IARC monograph restricts its inquiry to carcinogenicity whereas I am more worried about glyphosate's potential to impair my gut microbiome, i.e., decrease the total number of microbes or decrease the ratio of beneficial microbes to harmful ones.

            • titanomachy 2 hours ago

              Thanks, this is helpful context.

              Basically they conclude that the chemical has the potential to increase cancer incidence in some dose. But they are not making any statement about whether glyphosate as used in agriculture increases cancer risk?

          • cyberax 2 hours ago

            > The WHO says that it is.

                Did you read that link? Group 2 is pretty poorly explained to laypeople, Aloe Vera is listed as "Possibly carcinogenic", 2B.

                High concentration and quantity and long term exposure to glyphosate is probably bad for the farmers spraying, but their listing of glyphosate is completely irrelevant for the consumer buying a crop that was sprayed with it. They never once mention any danger to consumers in that entire article.

                Even in that limited case (occupational hazard), the data is mixed, and the IARC says that the US AHS study of 50k pesticide applicators did not find a correlation between cancer and glyphosate. They say that doesn't overrule the other findings.

                They are being hyperconservative for the safety of workers. That literally doesn't apply to you, the consumer.

        Of course it's easier for it to happen in nature than for them to do it in a lab. The way nature does this is that when you kill untold numbers of the ones that aren't resistant, you're left with the ones that are. If you used that method with our actual crops, you would nearly wipe out the crops and cause massive food crises.

        But not productively. In monoculture agriculture, all but a single planted crop is a weed by definition, and we have no way of making use of it at scale. Sure, you can eat dandelion greens from your yard, but that does not scale.

          You don't need to grow anything. You can just eat the plants. Just be careful in how you decide what plants to eat.

          My cats eat plants that somehow seem to grow out of concrete. I have no idea how a plant can even grow out of concrete at all, but it totally works.

          It probably has some minerals in it. Is it very nutritious? Probably not.

          You can also just eat stinging nettle. Make soup out of it. Free meal. One of the most nutritious plants that is available in almost all western countries, and probably grows outside of western countries too.

          It's... I dunno why people don't trust nature or the wisdom in their bodies anymore.

          Another example. Eat an apple. You're fine.

          Dig seeds out of the apple, crush them and turn them into a paste. If you eat that paste, you will die.

          Yet we eat apples all day. We trust apples. If something looks, feels and smells edible? Probably fine. Maybe ask a few locals like some birds, cats and dogs because they know nature a little bit better than you do probably.

There is no such thing as "herbicides" they are semi targeted biocides and are not maintaing there effectivness or targeted enough to prevent unacceptable "collateral" damage. Biology supports this as there are very few parallels to be found in nature for this kind of defence/offencive use of chemicals in multi cellular life.Which is a great big hint as to the true cost benifit equation over, reproductive time scales Many single celled life does of course use chemical deffensive/offensive products, yeast and various algae capable of powerfull effects on many life forms.
