Interest in alternatives to has grown quickly since concerns emerged over the herbicide’s safety. Its active ingredient, glyphosate, is branded as a probable cause of cancer by the United Nation’s International Agency for Research on Cancer.
But regulators in the United States have said glyphosate does not pose a risk to people’s health or the environment.At the same time, more than 13,000 claiming the pesticide caused non-Hodgkin lymphoma or other cancers have been filed in courts around the United States.Everyday consumers may be in a better position than farmers to adopt alternatives to Roundup. Large farms or landscaping operations may have a harder — and more expensive — time giving up glyphosate-based herbicides. Putting down a 2- to 3-inch layer of mulch will cut off the sunlight weeds need to sprout. Any weeds that manage to germinate will suffocate under the weight of the mulch.A handful of iron-based weed killers have been approved by the Environmental Protection Agency.
Broadleaf weeds absorb iron more easily and in higher amounts than the grass in your lawn. As the iron oxidizes, it kills weeds within just hours after applying it.Manually digging up weeds by the root may be the most effective way to get rid of them. It is also the most labor intensive. Organic Alternatives to Glyphosate.
Several brands of organic herbicides are available in the United States. They tend to use naturally occurring oils or acids to kill weeds. These products typically work on weeds after they’ve sprouted. However, they are not usually effective against perennial weeds.Organic options include herbicidal soaps that use fatty acids to kill weeds and industrial vinegar, which contains much higher levels of acetic acid than what you have in your kitchen. Acid-based herbicides burn down some young weeds.Corn gluten meal can kill grass weeds and broadleaf weeds. To use it, spread 20 pounds for every 1,000 square feet of garden. Wait five days to water the area if it hasn’t rained.
It should kill weeds for up to six weeks.Organic herbicides are most effective when weeds are still small and less effective as weeds get older, according to a study by the University of California Division of Agriculture and Natural Resources. Researchers at North Dakota State University tested a popular vinegar, salt and soap homemade herbicide formula in 2014. They found it was effective at killing small annual weeds.
It didn’t work very well on large annual weeds or perennials. Annuals are plants that only live a year. Perennials are those that live two years or more, coming back each year.The researchers found glyphosate was cheaper, but the homemade mix, using store brand ingredients, was still less than $3 a gallon. That made it practical for home use against certain weeds.The mixture can still be toxic to humans and animals if swallowed. Based on animal tests, the researchers estimated that a gallon of the salt and vinegar concoction was nearly 10 times more toxic than the store brand glyphosate they tested it against.
So it should be stored away from children and pets. You should also be aware that vinegar may contain glyphosate.
That’s because most vinegar is made with corn and most corn in the United States is grown from Roundup Ready seed. Those are crops genetically modified so farmers can continue using Roundup as the crop matures.“So the vinegar you are using to spray your weeds is probably made from corn that was sprayed with glyphosate: the very herbicide you were trying to avoid,” the researchers wrote.You might get around this problem by using certified organic vinegar. Farming Techniques, Other Herbicides and Robots as Alternatives. A study in 2008 in the journal called glyphosate “a once-in-a-century herbicide.” Despite the rise of Roundup resistant weeds, it’s been difficult for researchers to find anything that works as well as glyphosate at controlling weeds.But Bayer AG, the drug and chemical giant that makes Roundup, promised in June 2019 to spend $5.6 billion over the next 10 years on herbicide research.One alternative may be biopesticides, a staple of organic farming. They’re made of naturally occurring substances found in plants, animals, minerals, fungi and bacteria. The Environmental Protection Agency reported more than 18 million acres were being treated with biopesticides in 2015.Some farmers have switched to an older pesticide called. It can be sprayed on crops that have been genetically modified to be resistant to it while killing the weeds around them.
But it’s been blamed for drifting and destroying 3.6 million acres of unprotected crops in 2017 alone. Alternative Farming Techniques. New agriculture robots may soon take over mechanical weeding chores or reduce the amount of sprayed on crops.French company Naio Technologies has been testing its Dino weeding robot in the Unites States. Its operator types in instructions, such as field and crop row dimensions, on the four-wheeled robot’s controls. It then uses GPS and cameras to move through the field using cultivator blades to rip up weeds.The company says the electric robot can cover 12 acres in eight hours on its own. And it could potentially cut labor costs.
The New Food Economy, a nonprofit news organization, quoted a farm production engineer as saying one person could manage a fleet of 10 such robots, eliminating the need for 10 people to man a tractor each. Coupling robots with organic herbicides could be an economically and environmentally friendly combination.“We see these herbicides eventually being used commercially with camera-based precision applicators that ‘see’ weeds and deliver herbicides only to the weeds, not to the crop or bare ground,” W. Thomas Lanini of the University of California wrote in a report on research into organic herbicides.The solar-powered ecoRobotix does just that using artificial intelligence and cameras to navigate and to identify weeds as it passes over. Two robotic arms spray pesticide precisely on weeds. And it uses 20 times less herbicide than conventional sprayers. Why Is Roundup Still So Widely Used? Roundup became the first glyphosate-based herbicide when it hit the market in the 1970s.
Today, glyphosate is the most widely used weed killer in the world. Much of its appeal is that it is cheap and effective, according to researchers at North Carolina State University.In a 2018 Extension Service publication, weed scientists Joel Neal and Andrew Senesac wrote that glyphosate has several advantages over other weed-killing options. It kills a wide variety of weeds, doesn’t get into the soil and kill other plants, and it’s less expensive than other herbicides. The scientists said there are effective alternatives to glyphosate, but each tends to have a drawback.
They wrote that alternatives “will be, in some way, less effective, less convenient, and/or more expensive.”State transportation departments have looked at alternatives for controlling weeds along thousands of miles of highway right of way. A 2008 report for Massachusetts’ transportation department found the same problems the North Carolina State researchers found.“In general, the results suggested that, compared to conventional herbicides, the alternative methods chosen for research were less effective and more costly,” researchers wrote in their report.

I’ve tried my fair share of natural weed killers. From organic weed control recipes to weed blockers, here’s what worked (and what’s been less than stellar) at keeping weeds at bay.Here in the islands, some edibles grow like weeds. Avocados, liliko‘i, and papaya sprout in my compost heap all the time.
Want to know what else grows like weeds? And since I dislike spraying poison, I’ve done my fair share of experimenting with natural weed killers and other weed control methods. This is what our orchard space looked like when we moved in:This is what the same area looks like today:The photo angle is a bit different, but the tangerine tree in each photo (it’s at the center of the bottom image) will give you an idea just how much weed management we had to do when we moved in.I’ll be honest.
It would be soooo much easier to fill a sprayer with poison that would kill noxious weeds right down to the root. But it’s just not worth it to me to put my family’s health — and that of our planet — at risk. I’m pretty committed to organic gardening, both for my family’s health and that of the planet.The organic weed control methods I use around here vary, depending upon the location and type of weed. What is a weed?As someone once famously said, a weed is just a plant growing in the wrong place. The wrong place usually means that a human has decided they don’t want that particular plant in that particular place. Pulling weeds is an option, of course, but that’s time intensive. Mow the weedsAs evidenced in the top image, when we moved into this place the entire yard was overrun with elephant grass. It’s horrid, horrid stuff.
Elephant grass grows ten feet tall and the stems can be 1/2″ thick. When it can no longer hold itself upright, it falls over and easily roots into moist soil. It’s itchy and nasty and we didn’t want it here.Initially, we had to remove it by hand, but once we’d reduced it to short clumps we discovered that after a couple months of mowing it low to the ground, the clump just died. Obviously, this only works in wide areas that allow access with a lawn mower. For areas the we can’t reach with a mower, we’re using a Japanese sickle to cut them down by hand. (It’s my new favorite hand tool.)Mowing regularly prevents weed seeds from forming, which reduces weeds, too.Smother the weeds for organic weed controlI use this method around trees, shrubs, and perennials to create a weed barrier; essentially, areas where I won’t be trying to dig.Every that makes its way into my house goes into the yard and garden.
As you can see above, I flatten the boxes, remove any plastic tape, and spread them around the base of trees and plants to smother weeds. This greatly reduces the weed population, but its ugly. I generally cover the cardboard with wood chips or mulch. See below.As the cardboard and newspaper breaks down, the weeds will eventually start to come back. When I notice this, I just repeat the process. The benefit here is that the layers of mulch eventually break down and improve the soil.Burn the weedsFence lines and edges are the areas where a lot of people fall back on poisonous weedkillers.
Weeds Control Without Poisons Pdf Editor Software
I’ve found that using a weed burner works beautifully to knock down weeds at the edge of my garden beds. For the most effective weed killing action, repeat the burning soon after you see weeds starting to sprout again.I don’t recommend this method if you live in a dry region. You do not want to be the person who started the forest fire.Our place is pretty much green year round, though, so there’s not much risk of starting a fire if I’m cautious.Let the chickens scratchI’ve talked before about. Chickens are natural weed killers.
Weeds Control Without Poisons Pdf Editor Windows 7
A moveable chicken tractor will allow you to shift them around your yard into weedy areas without putting your garden at risk.Another trick? To get the hens to work specific areas — the fence line, say — and keep weeds down, I scatter scratch in those areas.Solarizing as a natural weed killerYou can use the power of the sun as a natural weed killer. It’s not a quick fix, though. Spread a dark tarp on the area where you want to kill weeds. Set a few rocks on the tarp to hold it in place, then walk away. Depending on the sun, it can take two weeks to a month or more to kill the weeds under the tarp, but it’s definitely a low-effort organic weed control method. From Tanya at Lovely Greens.
MulchI have adopted in my vegetable beds. I regularly top off my beds with a thick layer of grass clippings, adding more as young weeds emerge.The exception here is one horrible, creeping grass that I don’t know by name. It does manage to wend its way through the thick mulch. The mulch makes it easier to pull, though, so it’s at least a small step in the right direction.
Bonus:This method works well, but it does require a lot of mulch. Beware of bringing hay into your garden beds; you might.
I invested in a lawn mower bag to collect clippings rather than letting them drop. (Thanks for that suggestion, Angela!) We use those cuttings around the base of trees, but not in the veggie garden where they might root and become a problem. Shade the weedsMany common weeds don’t like the shade. You can take advantage of this and plant accordingly. This is more of a natural weed suppression method than a natural weed killer, but I’ve found it to be quite effective.Tighten up the spacing between your vegetable plants to shade and crowd out the weeds.
I have comfrey planted at the edge of my garden beds and I allow plantain to take root there, too. These plants both grow wide and close to the ground.
The shade they cast prevents weeds from taking root there. Can be used to hold down weeds in a vegetable garden. It’s a short-lived annual and will die down and become mulch for your veggies.is a hardy ground cover for use in warm climates; it will out-compete many weeds.
Just be mindful that it is deeply rooted and may creep into nearby cultivated areas. Boiling water is an indiscriminate natural weed killerThis isn’t practical for a big project, but when I have water boiling in the kitchen — from cooking pasta or, say — I take it outside and pour it on weeds. I usually reserve this natural weed killer method for weeds in the driveway or growing in cracks in concrete. Don’t pour it near any plants that you want to keep. The hot water could damage their roots, too.Salt is another indiscriminate weed killerFighting weeds in the cracks of your patio? Sprinkle them with salt.
Just don’t do it right before a rainstorm when the salt might be washed into the surrounding landscape. You can also use salt directly on weeds, so long as it’s not close to important landscape plants. You can see in the image above where I’ve used this technique to take out a very aggressive clumping grass. I cut the grass to the ground and covered the clump with about four cups of rock salt. In just a few days, the grass was completely brown in a sea of green.
Note that the surrounding green is not something I was concerned about damaging.Rototilling as natural weed controlTilling is a good way to knock down weeds and loosen the soil for manual weed removal. A can be very handy for weed control, even if you tend toward a no-till garden. Goats as a natural weed killerDisclaimer: I don’t have goats. But I’ve seen goats in action, most impressively at my friend Gary’s place. His property was steep and brushy, and in dry California, a fire hazard.
He brought in goats and the time it took for them to completely clear the area was nothing short of amazing. Here are some things to consider if you want to raise.Goats as natural weed killers are definitely not an option for, but if you’ve got a large area to clear and you can contain the goats, it’s something I’d look into. They offer natural weed control to the nth degree.
Natural herbicidesI’ve tried a couple of different “alternative” natural weed control products that I could spray on, in part, because wouldn’t it be awesome if they worked? And they do work, to a point.I’ve tried the vinegar potion that’s all over the internet as well as a. These herbicides are contact killers and will kill the leaves that are sprayed. They are not that will travel through the plant to kill the roots. Natural weed killers just don’t have the “oomph” of the poisonous sprays.I imagine that repeat applications of these natural weed killers could shift this into the “successful” column, but with our abundance of weeds and their invasive root systems, it’s just not a great organic weed control option here. Dealing with poison ivyWhen I talk about weed eradication with people, invariably someone will ask about poison oak or poison ivy. I’ve lived on properties with poison oak (not poison ivy), but thankfully it wasn’t too close to the well-trafficked areas of the property.
Our organic weed control for this nuisance amounted to “maintaining” it by cutting it to the ground every year.You should definitely head on over to Tenth Acre Farm, though, where Amy give a. (It’s a slightly different plant, but I’d expect this to work on poison oak as well.) Another way to deal with weeds?
Eat them.Originally published September 2016; this post has been updated.Click to save or share! If you have an area of newly-cleared forest which you want to turn into garden, an excellent way to clear it is with a few pigs.
Borrow or buy some pigs and set them up in the area with a proper shelter and good source of clean water. Securely fence off the area as well. The pigs will eat all of the vegetation, and dig up and eat the tree roots. When they’ve finished and there is more land to clear, just move the fence and let them start over again. The soil remaining, having passed through the pigs’ guts, will be seed-free, grub-free and ready to grow your veggies.
