Ashley is a soil scientist who has had a passion for plants since she was a small child. In the long summers as a child, she would garden alongside her grandmother and it was then that she realized her love for greenery. With years of great studying, Ashley had begun her post-secondary education at the University of Saskatchewan.
At first, her second love, animals, was the career path she chose but while doing her undergrad she realized that her education would take her elsewhere. And with that, four years later she graduated from the University of Saskatchewan with a bachelor’s degree in science and a major in Soil Science.
Some of Ashley’s interests are UA-cam, in which she posts informative videos about plants and gardening. The focus of Ashley’s UA-cam channel is to bring science to gardening in a way that is informative but also helpful to others learning to garden. She also talks about the importance of having your own garden and the joys of gardening indoors. Ashley continues to study plants in her free time and hopes to expand her UA-cam channel as well as her reach to up and coming gardeners.

The bacillus link just links back to this same video.
Thanks for letting me know ua-cam.com/video/SIwBqGt0tCY/v-deo.html
Um.. thank you? How about two videos- one called 'An in depth look at Glyphosate' (this one) and one that simply describes the process of removal including links to purchasables called 'How to Remove Glyphosate from your soil'. Because this video just irritated me. I know ABOUT it - I was looking for how to REMOVE it.
I live an hour outside Saskatoon, and ever since discovering your channel it has been my favourite for all things garden related. Great work, thank you for posting about this harmful substance I worry about it constantly. Thank you, great work, and may your success continue to lift us all as it elevates our knowledge, heals our planet, and nourishes our spirits.
That’s awesome! We are close to each other!
Saskachatoon.
So thankful for your insiteful, unbiased commentary on these touchy subjects that most UA-cam providers try and skirt around or provide slanted opinions. Where we were be without your channel???
HAHA gardening most likely
Refreshing and surprising ... to find a UA-cam site that takes an objective view on the topic of glyphosate. And what is even more surprising is that almost all of your viewers, judging by the comments, are of the same mind. Many thanks for your informative posts.
Haha yea the subscriber base on this channel is pretty analytical
I used it last year for a small food plot for deer, but it was only the one time so from how it sounds the soil there should be safe by now. Thank you so much for the summarized and easy to understand info ma'am!
Thank you!! Have no idea what is in my soil. Much appreciated.
Yea you’ll never know it’s impossible. Soil is so dang old
I'm here because you deliver science!
Thanks!
Wow really enjoyed this
I am glad!
I’d be super interested to see a video about algea in the soil if you don’t already have one. The next frontier!
It’s super interesting to get the science on this, thanks! Puts my mind at ease about reluctantly using it occasionally (and only on the greenery, not the soil) for noxious weeds like creeping bellflower and canada thistle. I’m assuming that since it is pulled down into the roots of the plant that it would still kill the plant’s localized fungal network, but hopefully not more than that!
It’s pretty darn safe and completely okay to use for the troublesome weeds. ua-cam.com/video/SHiQcgFMpMs/v-deo.html
Thank you for your unbiased facts! Still won’t use it but allows me to put the past in the past!
You are so welcome!
I've read that even the organic society, not saying what I read was correct, said it appears to be pretty harmless in the soil and is mostly not showing up after 3-5 days of it being sprayed. Yes, long term herbicides work to control weeds from germinating that are totally different. Good job, good video! Thanks
It’s essentially 72 ish hours for most herbicides
@@GardeningInCanada It seems that the biggest problem with herbicides or other chemicals is getting them on you or in your mouth.
Yea
@@GardeningInCanada @milkweed7678 for the the full glyphosate compound, but NOT it's metabolites! AMPA is actually considered both a persistent pollutant and a more harmful compound that glyphosate! Wish this video had better information.
@@milkweed7678. Wear a mask when you’re using it. (Most of us have a few Covid era masks hanging around somewhere)
Hi. I really appreciate this video. I do no dig, organic gardening and have no problem pulling weeds by the way... 😁
However, I have bindweed. For years now it has been making me crazy because there is no "pulling it". You have to dig down a good foot to get all the roots. Tilling just cuts up the roots and make thousands of new babies.
This year I finally broke down and got some round up. Of course I will be "only" using it on the bindweed but I have been very worried about when I can plant into the soil without the plants drawing out the chemicals from the soil into the vegetables.
This was very helpful. Thank you.
you eill be totally fine
Solarization? Let it fallow for a summer with a tarp on it. I feel like I should of done that instead of round up.
Could you look into persistent herbicides. They often get sprayed on hay and can persist through the digestion of animals cuasing contamination of manure.
Long story short is I've been screwed by this. My horse gold turned out to be horse garbage that was killing my tomatoes.
Yes! Absolutely
Thanks so surprised Roundup isn't almost poison for the next generation to deal with,
As Stewart of the earth we should have these things explained as they come up.
Thanks 😊
Yea. There are pesticides out there particularly insecticides that will get passed down though.
Hi, did you do any research in to Aminomethylphosphonic acid (ampa)? It's one of glyphosates main metabolites and considered pretty resistant to further degradation and keeps accumulating. It also brings similar health concerns as glyphosate.
Thanks for the information!!!
I'm looking forward for the Rockdust and Chitin video!
I know I’m sorry I’m working on it I promise!
@@GardeningInCanada sorry wasn't trying to rush you haha. Take your time and hope you have a nice day:)
Ha ha no I know. I just don’t want you to think I forgot about you
If you use the weed wicking method, does the glyphosate leech into the soil from the plants it’s killing or remain in the plant it killed that dies and breaks down and eventually leech into the soil via the degrading plant carcass?
I’m battling quack grass that spreads via rhizomes and is hard to get all the underground roots, I’ve pulled many but many more keep coming.
Thanks for the video! Did the fungal study go into whether it's a direct effect on the fungi or a side effect of plants dying (mycorrhizal fungi losing their hosts, etc)?
It was spore damage so damage via soil contact. But there will be losses from the hypea as well once the host is gone. Great point!
Thank you for the video. Please can you send more info on the very scary pesticides.
My property borders an agricultural field in upstate ny. They use glyphosate every year. This year they planted soy beans. They sprayed the other day and killed a 2 ft strip of my lawn, I had potatoes planted on that edge and they got hit, the first 2 plants are completely dead. Nasty stuff. Thanks for the information
Spray drifts in even light winds
AND THEN TO WATERTABLE AND EVENTULLAY INTO RIVERS TO OCEAN. ITS WATER
SOLUABLE
THEN SOME EVAP. TO RAIN.😢😢😢😢😢😢
@@MrSummerbreeze01 The chemicals are still present for months after spraying, and will therefore continue to pose the risk of drift through volatilization.
Very informative
Glad it was helpful!
Thank you for this informative video!
Can you do a video aminopyralides?
Yea sure!
Ashley, i need your opinion please! My neighbour spray killex 1 m away from the fence. I want to plant caragana pea shrub along that fence to have peas as a chicken feed and peashrub flowers for tea medicinal purposes and to also protect my garden with the live fence. Do you think my shrubs will absorb it thru the roots making ut unsafe for consumption? Thanks
Do you know that garbanzos are sprayed with Roundup day of or one day before harvest? They receive 3 to 4 sessions of spray.
How can I replenish the fungi that was killed roundup has killed? I've noticed my weeping willow had a large black spot outbreak after I sprayed weeds under it. I know it was stupid now. Please help.
Any tips for getting good algae and beneficial microbes for my garden? I live in Coastal Southern California if that matters.
focus of diversity in compost, crop rotation, ensure good soil moisture.
Which herbicides do you classify as dangerous because they stick around?
I wanna know how long that new water clorine lasts..i been taking water outta the dog pool thinking it was gone.after.teo three days...it needs cleaning a lot...usually some algae looking stuff starts growing on the wall...ao figured it was gone...but maybe not.
Who paid for your studies? There can be a great influence with the result. From farm girl, Linda
Thank you so much for this information. Im really concerned about the other pesticides and herbicides out there. I would love to hear about them. I have very small amount of knowledge but do know they are all bad. I know my dad telling stories from when he was a kid and all these sales persons trying to seek synthetics to my grandfather and hidden secrets in California agricultural practices my uncle shared with my dad. Fro. The use of car oil to dip veggies and what not. My God.
Subscribed.
Thanks!
Thanks for the research -- Question: I use my neighbour's grass clippings for mulch. He occasionally sprays for broad-leafed weeds but doesn't give me recently-sprayed clippings. Would residues affect soil health? My veg doesn't seem to suffer at all after laying it down. Would composting the clippings destroy any residue or would it actually do harm to the composting microbes. Thank you!
No highly unlikely. It’s 30 days max that it resides in the swell. And I would say so long as it has been sprayed in the last 14 days you’re fine. And the event has been sprayed within the last 14 days I would simply just let it sit for a small period of time and I warm moist area. Let my crows do their work and you will be just fine
I will call microbes 'my crows' for the rest of my life now. Please don't edit the comment.
@@GardeningInCanada I have heard lots of reporting of problems with amino pyrolenes, or something like that I forget the name now, which is a broad leaf killer and even contaminated hay and such. Glyphosate kills everything, I think, including grass, so not a broad leaf killer. Dowding and many other youtube gardeners have reported this. Try growing a few bean seeds in you're suspected contaminted soil as beans are supposedly vulnerable.
Hahah omg I just saw this
If you figure out what the name of it is send it my way and I can maybe shed more light on it.
8.00
I think the abbreviation, ug, must be short for microgramme and it would be better to read it as such. I think people use, ug, if they don't have the greek letter, mu, available.
Interesting information. However, as it is more than just the affects of a one time application within the context of a study I will not use it and I do my best to find products that have been grown without it and are not desiccated Thanks for sharing your perspective..
What i would like to know is how much you’ve been paid by Monsanto. You have completely bypassed what glyphosate is and how it works. Glyphosate is a kelation agent if you dont know what that is look it up in addition it is an antibiotic. So let me educate you how it works. Glyphosate when its sprayed on plants works systemically by binding with minerals in the plant and shutting down the immune system and the plant extrudes the glyphosate into the soil which in turn acts as a antibiotic that kills good microbes and promotes pathogens that ultimately give plants a terminal infection and kills it which is why when it is sprayed on a plant in steril soil the plant may stunt but wont ultimately die. The other thing is glyphosate hangs around and its effects hang around for years and completely changes soil biology which in turn affects the very food you eat. I could go on and back it up with real world data. All i know is that my wife passed away from the constant use of commercial fertilizers and pesticides, and i know of a lot of people that are sick and dying because of the constant use of glyphosate, in addition i have real world data that shows that since we stopped using glyphosate and dicamba based products our solid are flourishing with good micro biom the earth worms have returned to our farm we have more available nutrients for our crops to uptake so which means less commercial fertilizer, using cover crops and inter seeding practices to out compete noxious weeds, and i have a clear concisens knowing that i am not part of the problem but of the solution because i call out people like yourself.
I know for sure the guy who owned my house a year ago be4 us was spraying herbicides. I planted trees and new garden beds and they seem to be doing ok, i even got a harvest. I think it decomposed in 6 months.
Unfortunately this year I put down straw for mulch on most of my garden beds. I have done this for many years with never any issues. However this year I have finally figured out that the straw must have been heavily contaminated with dessicant (glyphosate and maybe other chemicals). Every bed that got it was decreased yield by at least half, some almost completely no production. Most plants just struggled to grow at all and none reached normal heights. The basil didn't germinated well and required reseeding and then still only grew a couple of inches in 2 months. The tomatoes were the key to figuring out what had happened and showed the curling, etc of herbicide damage. The beds that didn't get mulched produced normally and in abundance. Overall, it's very discouraging and disturbing. My question is. Does the fruit or vegetables uptake it at different rates? What is safe to eat or now is it all garbage? Are the root crops now all contaminated? How about the above ground fruit or cabbages? There are a lot of studies on the problems with glyphosate in the human body. If it can kill or disrupt growth just from the straw, it is disturbing to think we eat the grain that accompanied it. I'm hopeful that my soil will recover completely. Thanks for all your videos.
Every corn chip you ate for the last 20 years was from a corn plant sprayed with glyphosate. The farmers typically spray it when the plant is less than a foot tall so the residue on the final crop has to be near zero. If they are spraying the wheat or oats a week before harvest to kill off the wheat / oat stalk or residue weeds then you could very well have Glyp in your straw that was not broken down yet because it had not contacted the soil. Find a Gly free source for your straw.
I purchased a couple of bales of "Just Straw," because it claims to be just what the name suggests. So far, so good.
It is almost scary the way I did gardening many years ago. I think I still have a jug of roundup in the garage. The thing is we are a society based on commercialization. Use this and all your weeds will disappear, yeah right. Glad I changed things around. Thanks for the info.
Haha yes… agriculture shows they used to drink round up when I first came out to show it’s harmless 😬😬😬
@@GardeningInCanada Drink away big AG
Hahahah RIP 🪦
Hopefully you have not allowed your herbicide to freeze.
Whats your opinion on pyralid?
So that stuff is wicked! And that’s what I mean by glyphosate being a cake walk.
This is justified a synopsis of environmental dangers described by the company:
“TOXIC to non-target terrestrial plants. Observe buffer zones specified under DIRECTIONS FOR USE.
The use of this chemical may result in contamination of groundwater particularly in areas where soils are permeable (for example, sandy soil) and/or the depth to the water table is shallow.
5
To reduce runoff from treated areas into aquatic habitats, consider the characteristics and conditions of the site before treatment. Site characteristics and conditions that may lead to runoff include, but are not limited to: heavy rainfall, moderate to steep slope, bare soil, poorly draining soil (for example, soils that are compacted or fine textured such as clay).
Avoid application of this product when heavy rain is forecast.
Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip between the treated area and the edge of the water “

When you know people who are sick from glyphosate exposure in their environment this video is so deceiving.
I’ve got a garden that has been over taken with mint. Every year I pull as many roots as I can find and it never helps by early to mid summer it’s everywhere again. Will glyphosate kill the mint and roots for good? I can deal with the consequences and re build the soil over time just need the mint gone. Thanks for any info
yes its awesome stuff. 3 ounces per gallon of the 41% solution of glyphosate in your hand sprayer. Add 1 tsp of liquid miracle gro to enhance
What about triclopyr? Do you know how it affects the soil bacteria and fungi and how long it lasts in soil?
ooh thats a systemic. i can do a video on that
@@GardeningInCanada please herbicide of pyridine group. On Hay to manure to compost to soil. What about that
glyphosate. Would you want to put poison on the soil & plant your food in it.what part of poison don't you understand?
It's the only solution for Japanese knotweed but that's all I use it for.
Yea absolutely that’s fair.
You can dab glyphosate on the foliage with a weed wick, you don't have to spray it.
Couldn't find the link for the raised garden beds.
Oh! Totally forgot! Thanks for reminding me.

Thanks for this, its been a concern of mine ever since buying a small farm with 7.5 acres which has been treated with Roundup early 2021. The main reason for treatment related to a type of grass or rush which grows almost like corn is damp climates, its near enough impossible to eradicate hence the previous owners resort to using chemicals.
Last years dead rushes are still present with new growth appearing around the dead stuff, I assume this means the Glyphosate is no longer present or active but wondered if it may linger on the dead growth,(stalks) this is not below ground where microbes are active but does benefit from UV rays, any pointers appreciated - thank you
Yea absolutely! I can see where people get scared it makes ABSOLUTE sense. You are just being smart and doing your research.
Is it likely there are any residues left on the old growth from last year as I hope to use a topped then compost the cuttings, many thanks
I actually prefer glyphosate than most 'organic' ones just due to its less caustic / toxic chemical nature. The interesting thing in this discussion is application and drift that causes most of the accidental issues in close quarters gardening. Someone shooting the ground tells me they didn't read the label. Someone shooting in windy conditions next to a tomato patch or tree likewise. Dicamba and 2,4-D might be another one to tackle which occasionally rears its ugly head (via straw/hay bales) but luckily general application isn't available without a license - but can still be an issue when someone in the neighbourhood sprays their lawn by a licensed applicator that's lax.
I guess specifically in relation to the hay/straw thing, would it be worthwhile to go over doing bioassays when dealing with new mulch providers, etc?
Yes. I love all these points
Yes so straw mulch you really need to watch on
Here in the US 2,4-D is regulated kinda funny. Without applicator license you can still buy as much as you want as long as it is in small bottles. The licensed one can buy as much as wanted but can get gallon bottles to 55 gallon drums. Same goes for glyphosate. Some stuff is highly regulated and some is supposed to be but in effect, its just regulations on size of container you can buy. With noregulation on how many can buy. Chem application can be realy touchy. I once did a roadside tree spray job. The Chem could easily kill crops 5 miles away when caught by the wind. Of course that stuff you can't get without the applicators license.
I was thinking of using a weed torch on my one garden bed before I plant As it is FULL of weeds every year . Not sure how much that will help
A tiger torch type setup? No issues with that
@@GardeningInCanada thanks!
Anthony Samsel and Don Huber have researched the effects of glyphosate on health .
Nice review.
Thanks
💚💚
❤️❤️❤️
Please cover atrazine??? PLEASE!
I’ll put it on the list!
I should maybe do a common pesticides in the garden series where I go through each one type thing
Fungal activity is so important for trees ! for anything grape and fruit trees glyphosate is bad. In the human body, while proven to be non-toxic for human cells, those are only 10% of our body composition, so imagine the rest. It puts imbalance into microbiomes of various body parts, and those micro-biomes produce things that relate to immune system, digestion of nutrients, and help our organs to filter other harmful toxins (liver pancreas thyroid kidneys). So very low doses of glyphosate are present in 100% of humans urine. It's close to impossible to be free of it, it's in bread, pasta and seed oils, and washing the vegs does not remove it. So even low doses can impair digestive processes, and it can be the small thing that make a person tip over and loose either true balance (meaning falling) make bones weaker, loose muscle with aging faster, promote various cancers, etc. Most modern human diets are mostly unhealthy, so most of the time very little is enough to tip a person into severe health issues. 6% of American people are metabolically unhealthy. vegan => back pain, lower brain health, mitochondrial dysfunction and diabetes => Alzheimer etc. Regenerative agriculture requires animals and we are omnivores. Humans dominated the planed because they were mostly plant based in the good seasons and hunters in winter, each season detoxes us from the other, it is this wonderful digestive tract that also enable days of fasting that helped establish human dominance over the Earth, and we are killing it. (sadly glyphosate is not the worst, there are antibiotics and other scary things)
Deadly to all things aquatic . And sooner or latter it finds its way to water.
'get on your damn knees and pull some weeds'. I'm hip to that. My grandma can do it, she is definitely not lazy. She has never needed 38 metric sh#ttons of wood chips to get through her gardening year. (For you Canadians I put it in metric terms)
HAHA I love the canadian conversion thank you
Going to take my kiddo to one of those “professional human bodies” people today 😂
HAHAHA
Glyphosate is benign when compared to Dicamba
Off topic: I can't help but see an old man with a white beard in the grow tent
Proper use of round up and such is key.
I've had people ask if they could till the soil and then stray the soil with roundup to make sure the weeds are killed!!!.
That's probably why round up is getting such a bad rap.
Yeah not the issue. And that goes for pretty much anything including organic fertilizers. You used too much of that you are going to have negative impact
it is the only thing that seems to kill Creeping Charlie. My garden area is repeat with Charly and bind weed, and even though I am not in favors of these types of chemicals, I am going to use Roundup on my garden early in the spring next year to stop these perennial weeds from wreaking havoc in my vege garden
Is creeping charlie and what do you do about it if you do?
That’s a pain of a plant
Try borax.
Steaming hot water does the trick just fine if you can't weed with your hands.
Yes! Or vinegar 😏
@@GardeningInCanada Wonder if boiled streaming vinegar works very well?
Oh god yes! Rip 🪦 weedd
I realize this isn't really your topic, since it's not about soil, but what I've read about glyphosate for example is - it doesn't stay (permanently), but then again it's not the same as it used to be(?).
It's more about the harm it does to the insects, meaning it kills them(?).
The company/owner, Bayer (Monsanto) is behind so many more toxic(?) pesticides and also had some sort of idea of owning the rights to handeling with seeds (selling and buying somehow), however that was? But kind of like - in the end me and my friends wouldn't be able to swap seeds with each other (or rather me and my neighbor, small garden societies, and such couldn't sell seeds between each other) 'cause the company would somehow own the management of seeds.......?
As you can see I havn't got a clue what's right, rumers or pure falsehood? But kind of like - therefore meaning you wouldn't want to place your money in that company... But whether that was a continuation of "this is a bad company" I have no idea!?
But it feels good knowing that it's not a pure disaster if the neighbor starts weeding the gravel path with roundup (phew!)...even though I still wont do it myself...... 😄
Thanks for another good topic! 👌🌱
So most research has shown it’s dangerous to insects when it’s misused. Which unfortunately happens often in unregulated/hobby industries forestinfo.ca/faqs/do-glyphosate-based-herbicides-affect-honeybees-or-other-beneficial-insects/
the roundup formulation makes glyphosate more harmful, and after the glyphosate breaks down, the metabolites sadly accumulate. It's true that monsanto does patent seeds, and it also means the farmer has to buy new seeds every season and can't reuse from their own crop. I don't think glyphosate should be allowed for home/hobby use, but misuse also happens with the development of glyphosate-resistant crops, that allow you to use more glyphosate to kill everything else without harming your crop 😳
@@GardeningInCanada Thanks for the link! Yes, whatever we're using I have to admit it scares the living sh*t out of me what we're doing to the insects and environment
So basically 30 days...i would of thought 10 years..
Simple I never used it.
Yea we don’t use it either but if you just purchased a house you really have no way of knowing right
Use a paint brush! It’s more effective!
I've also put on rubber gloves then cloth gloves over them and get some on the cloth glove.
Now that’s ingenious! Bruce this is why you are one of my favourite subscribers
Oh yes!
Second this. This is how I do spot application on japanese knotweed (argh).
I'm not sure if the spellcheck is playing with you or not. Blink twice if you think use as a desiccant is bad.😬
😂 I don’t use any sort of pesticide at all I kind of just let things run their course. If it works out it works out 🤷♀️
Okay I lied! I use a tiger torch sometimes on my brick pad 🙄
@@GardeningInCanada I'm not sure we are on the same page. I mean pre-harvest application on cereals, like wheat and oats to speed up maturation. No need to answer because I know these topics can be sensitive, but the spellcheck in the info bar makes me laugh.
Oh on the farm we do a pre pass all the time you basically have to in a lot of cases. If there is a type it’s my dang voice to text/being in a rush this morning 😂 I’ll take a look
gravel site and glyphosate are the same thing right 😂
Milk weed:the weeds are 100% safer than glyphosphsate.
And your Monarch butterflies will thank you.
while i appreciate your input, i am not going to be handling or purchasing and thereby supporting this business, nope, not for me. not roundup and cancer.....
I really appreciate this comment! Most people just get vicious about having a polar opposite thought. The fact that you said you appreciate the commentary but prefer not to use it for valid reasons is beautiful!
I am reading this comment after getting some personal attack ones for disagreeing with me. So this comment means a lot in the moment.
I got farty for two days after drinking it.
Personally I don’t like herbicide you think it would be possible to do commercial farming without these products
yup! lots do. Sometimes it involves things like tillage or burning.
What about using vinegar does it distory the good bacteria in the soil
Farming, maybe; environmental conservation, definitely not!
2 minutes of facts 20 minutes of useless chatter
Let me simplify it.
*Let me really put it into perspective for you using science and math:*
Caffeine has an LD50 of approx 195 mg/kg compared to glyphosate at approx 5000 mg/kg ingested and approx 10,000 mg/kg dermal which is even lower than table salt with a dermal LD50 of approx 3000 mg/kg!!!! Yes caffiene is more toxic than glyphosate according to the LD50 method not mine. But, hey, its what we have to use right?
*Here is a hypothetical:*
If you were to calculate consumption of a 12 ounce can with a 3% solution of a 41% glyposate concentrate (about an average spray solution) compared to the consumption of a regular can of cola with the toxic ingredient, caffeine, for a 200 pound male. Here we go:
First, let's calculate how much glyphosate is in a 12-ounce can with a 3% solution of a 41% glyphosate concentrate.
Convert the 12-ounce can to milliliters:
12 fluid ounces * 29.5735 mL/fluid ounce ≈ 354.882 mL
Calculate the volume of the 3% glyphosate solution:
3% of 354.882 mL ≈ 0.03 * 354.882 mL ≈ 10.646 mL
Calculate the amount of glyphosate in the 3% solution, using the 41% concentrate:
41% of 10.646 mL ≈ 0.41 * 10.646 mL ≈ 4.365 mg/mL of glyphosate
Now, we have already calculated the LD50 of glyphosate to be 5,000 mg/kg for rats, and the weight of the 200-pound person to be 90.72 kg. The total amount of glyphosate needed to reach the LD50 is 453,600 mg.
Calculate the number of cans needed to reach the LD50:
number of cans = total glyphosate amount (453,600 mg) / glyphosate per can (4.365 mg/mL)
number of cans = 453,600 mg / 4.365 mg/mL ≈ 103,921.7 mL / 10.646 mL ≈ 9,765 cans
So, a 200-pound person would need to consume approximately 9,765 cans of a hypothetical beverage containing a 3% solution of a 41% glyphosate concentrate to reach the LD50 level of glyphosate toxicity. *Keep in mind that this calculation is purely hypothetical, as glyphosate is not an ingredient in any beverage and should not be consumed.*
*Now:*
The average amount of caffeine in a 12-ounce can of cola is around 34 mg. Using this value, we can calculate the number of cans required to reach the LD50 of caffeine, which is approximately 195 mg/kg for rats (note that the exact value for humans may vary).
Calculating the number of cans required to reach the LD50 of caffeine toxicity for a 200-pound (90.72 kg) person, we can use an average LD50 value of 195 mg/kg:
LD50 (195 mg/kg) * weight (90.72 kg) = 17,690.4 mg of caffeine
We know that the average amount of caffeine in a 12-ounce can of cola is around 34 mg:
number of cans = total caffeine amount (17,690.4 mg) / caffeine per can (34 mg)
number of cans = 17,690.4 mg / 34 mg ≈ 520.3
So, a 200-pound person would need to drink approximately 521 cans of cola (rounded up) to reach the LD50 level of caffeine toxicity, based on the accurate LD50 value of 195 mg/kg. Keep in mind that this is a hypothetical calculation, and individual reactions to caffeine may vary. It is important to consume caffeinated beverages in moderation and be aware of the potential health risks associated with excessive caffeine consumption.
*In conclusion*
The consumption amounts to kill 50% of a population of 200 pound persons:
9,765 12 oz cans of 3% glyposate 41% concentrate
VS
521 12 oz cans of cola with 34mg of caffeine
*Stunning isn't it, especially when you do the math!* Also, keep in mind that glyphosate is not meant/used for consumption. People are usually only exposed to glyphosate dermally or inhaled. Ingestion can occur but someone would have to really be thirsty to do that. Maybe (according to studies) glyphosate residue remains in the soil to kill the bacteria as you state, but I would like to see the studies that prove new crop plants are uptaking the glyphosate so that it is somehow passing onto grazers or humans via crop consumption. Please enlighten me.
*Furthermore*
The LD50 rating is the acute (short term) toxic effect. There are no scientific studies that can accurately measure the long term effects. Read the method of the LD50 studies if you don't beleive me. So the claim about glyposate in the body is a stretch to say the least. But I bet you can find a good amount of caffeine in your every day Starbucks/Dutch Bro/Dunkin/Coca Cola connoisseur. Lets drink them toxins! wohoo! Yet, I don't hear Ms. Ingham trying to shut them down any time soon!
Elaine Ingham is simply pushing a narrative for notoriety and a Monsanto hater. And she needs to make a good living to pay for her alphabet soup credentials. Haha!
For Ms. Ingham: Man turning any dirt into soil is not a natural event.
