Is Glyphosate (Monsanto’s Roundup) Used On Wheat? — 39 Comments

  1. I dove into this conversation too… same responses.. I have seen all the references you mention.. one states “facts” from USDA but I cannot find a primary source.. also the Monsanto guide is for canada which doesnt show the legality of use in the US.. if you find any better sources let me know, thanks.

    • Thanks for your comment. I have also attempted to find additional sources of information and have not found better ones than the Samsel and Seneff study I have already linked.

      None of us can be an expert on every subject, and I am certainly not on this one, but I have chosen to accept the evidence presented in this study. I have heard Dr. Seneff talk on the subject of glyphosate and find her dedication to research to be compelling. Her study with Dr. Samsel presents numerous charts and also names the person who collected and analyzed the government data on the use of glyphosate on wheat in the U.S. Since it would be very difficult for me to duplicate their research, I choose, as we all have to do sometimes, to rely and trust the results of this study. This does not mean that I automatically trust and rely on every study that is published. As far as I can learn Dr. Seneff has no conflict of interest that would distort her research into glyphosate and its effects on health.

      I appreciate your calling my attention to the Monsanto guidelines being from Canada. I could not find similar Monsanto published guidelines for the U.S.; however, I did find many more references to the use of glyphosate/Roundup for preharvest management of conventional wheat crops in the U.S. There were also implications that the U.S. had fewer regulations on the use of pesticides than Canada, but I could not verify that.

      I also found that the U.S. allows some glyphosate residues even on organic crops, and that those residues have been found on organic grains, especially barley. Buying organic may not prevent exposure to this herbicide. [source]

      If I find additional information on this issue, I will update the post.

        • Monsanto does encourage the use of Roundup (glyphosate) as a pre-harvest treatment in the Canadian guide that you referenced. (I included one chart from that guide, and a link to it, in my post above.) Apparently Roundup was approved for this use first in Canada and later in the US. The pre-harvest treatment of wheat with glyphosate is also included in several agricultural extension service online sites.

          • ABSOLUTELY, Carolyn. As you note, there are many references by mainstream agricultural agencies and organizations acknowledging this pre-harvest use of Roundup (glyphosate). For farmers and ag industry people to deny this and call your report ‘bogus’ is irresponsible or purposely misleading. Certainly not all wheat farmers use this practice, but there must be some significant number that Monsanto markets to that do.

      • Thank you for digging into this I watched an interview with dr. seneff and had many questions and I also can across the article from huff. Post truth about toxic wheat. Coming across your comments has helped a lot.

    • I can say for a fact it is being done in NE Colorado. I witnessed it in two center-pivot wheat fields bordering the South Platte river five or six miles from my own farm. The smell of Roundup was absolutely overwhelming. I at first thought there must have been a large spill. About two weeks later they harvested the wheat and it seemed like they were about a week or two ahead of the other wheat farmers who didn’t spray. This year was the first time I ever saw this around here, although I’d guess it’s been going on in places for some time.

  2. On page three of my Google search, I found references to using Roundup on wheat: University of MN (2009) and University of Illinois (1998). This info supports that it is not a new practice. Also, it is endorsed by land grant institutions, which makes me think the practice is mainstream.

    • Yes, I found those links also and agree that this is probably a mainstream practice, at least on large wheat farms. Maybe it is not necessary on smaller farms. I suspect that most processed and packaged foods that contain wheat are contaminated with glyphosate unless they are organic, and even some organic wheat may contain traces of glyphosate, although less than the non-organic wheat.

    • Thank you for your comment and the links you provided. I am glad to learn that you do not use glyphosate on your wheat crops and that many other wheat farmers also do not. Further research does seem to indicate that glyphosate is used for harvest management of wheat primarily in far northern states, such as Montana, and in Canada, where the growing season is shorter.

      One problem we have as consumers is that we usually have no way of knowing where the wheat in our bread is grown. Was the wheat grown in a far northern state where glyphosate is used or in a more southern state where it’s unlikely to be used? Until we have better insight into the source of our food, especially better labeling, buying organic is probably our best option, although glyphosate contamination has been detected even in organic wheat, probably from pesticide drift.

      It seems to me that the very significant correlation between use of glyphosate and the incidence of many diseases (see my post on the subject) warrants further study into its safety rather than increased use on any crop.

      • Carolyn, Kathleen did not say that her farm does not use Roundup on the land wheat is to be planted on. She said they do not use it in this way as a pre-harvest application to kill the crop so it dries more evenly and harvests easier.

        • Although Kathleen did not exclude the use of glyphosate on the wheat on her farm for purposes other than pre-harvest manaagement, it is probably unlikely that she would apply it to wheat except just before harvest. Conventional wheat is not yet engineered to be glyphosate resistant (Roundup Ready) and would be killed or severely damaged by application before time for harvest.

          • No, wheat is not a GMO crop, however, most farmers who use glyphosate with non-GMO crops apply it prior to planting to kill all weeds growing on the land.

  4. Articles published by NIH, via PubMed are peer reviewed and thus the science is more proven and reliable. Here’s a great study on it here http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3945755/

    Here’s another one from 2005, where Roundup’s glyphosate with it’s inactive ingredients were found to be as least twice as toxic as glyphosate alone.

    …from 2005…

    This is not on NIH, however does link to NIH published studies http://www.globalresearch.ca/monsanto-roundup-the-impacts-of-glyphosate-herbicide-on-human-health-pathways-to-modern-diseases/5342520

    Additionally, another good web search is “glyphosate and Shikimate pathway”
    A great NIH published study on that as well. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC440734/

    But, hey, those worried about the next quarter profit, the government has you covered… House Passes A Bill That Restricts Scientists From Advising The EPA
    http://io9.com/house-passes-a-bill-that-restricts-scientists-from-adv-1661140635

    Honestly, in a country full over people struggling to lose weight and garbage cans full of discarded food…surrounded by nations struggling to eat once a day… it’s absolutely disgusting to squeeze a few more seeds of wheat, or beans, or fruit, by exposing the consumers to toxic chemicals that are slowly poisoning us.
    It’s illogical. And plain stupid. History would have to describe this era in a way that’s simply embarrassing to all of us alive today.

    Keep bringing us the good stuff. Thank you!

    • Thanks for the comment and the links. Those are good articles. I think we are being very short-sighted to contaminate our land, water, and air with glyphosate and other chemicals in order to increase profits.

      You might be interested in reading my later post about a new study that found a significant correlation between glyphosate use and the incidence of many chronic diseases. The researchers for that study provided some of the data that Seneff and Samsel used in their study.

  5. Carolyn,

    I’ve noticed that every farmer who has replied to you has said they do not do this, nor do they know anybody who does. As I rent out wheatland in Oregon, I checked, and our land also does not support this practice.

    Your response always seems to be you have faith in the author and styill believe it is a wide scale practice.

    I guess my question to you is have you personally heard from ANY farmer in the US that uses this practice? If not, why the faith and why not take the time to find a farmer who actually does this.

    • I’m glad to know that your farm does not use glyphosate on wheat, and no, I have not personally heard from any farmer that uses glyphosate on wheat and do not expect to, for several reasons.

      One, it should be apparent to my readers that I don’t approve of the use of glyphosate on any crop including wheat.

      Two, it is unlikely that any farmer on a farm large enough to be using glyphosate on wheat would be reading my blog.

      However, my acceptance of the data is not based on blind faith, and, although I am skeptical of the validity of many government mandates, I haven’t yet learned of a reason to suspect that government data on the use of pesticides in the US have been falsified. The data in this study about the use of glyphosate come from government sources: USDA (United States Department of Agriculture), NASS (National Agricultural Statistics Service), and CDC (Centers for Disease Control). If you have information that indicates these government data are incorrect, I would appreciate knowing about it.

      The statistics that concern you are probably skewed heavily in favor of the very large mono-cropping farms which are much more likely to be using glyphosate. As I said in answer to an earlier comment, if we could always know where the wheat in our food came from we might be able to more safely use some conventionally grown wheat; however, since we don’t, and usually cannot, know, the best way to avoid glyphosate is to buy organic foods. In the ideal situation, we would know personally the farm and the farming methods used, but that is not always possible.

    • Thank you for your reply and the observation about what Farmers are actually doing in practice. I am a bread baker and have often used wheat grown from local farmers in our state of South Carolina. After seeing Seneff’s research article, I interviewed farmers who grow wheat here and they also confirmed that none of them use the practice of applying glyphosate to wheat at any time during growth or harvest. I too noted that Farmers writing in said they did not know of other farmers using this practice. Most agreed it would simply be a waste of money and increase the cost of wheat. I think it would be wise to do more interviews with wheat farmers before concluding that it’s a widespread practice in the US.

      • As I have said earlier, I am glad to learn that many small farmers, maybe even most, do not use glyphosate on their wheat, especially those in the lower states. The research seems to indicate that the primary users of glyphosate are larger farms in the northern states and Canada where the growing season may be shorter.

        The charts showing the amount of glyphosate used on wheat in the US are not based on interviews with farmers but on government data. Do you have information that these data are incorrect?

        • Apparently OATS have been treated with glyphosate– (Roundup (R) before harvest more than wheat, from what we are hearing from US farmers. Grain Millers, a major oat buyer in Western Canada, will no longer purchase oats if the crop has been desiccated with glyphosate.

          In an April 20, 2015 memo to Canadian Prairie oat growers, Grain Millers said the new policy was “driven by functional performance attributes of finished products manufactured from oats known to have been treated with glyphosate ( they crumble) and by customer demand.”

          • Thanks for the information about glyphosate use on oats. When organic supplier Tropical Traditions tested their organic grains they found traces of glyphosate on wheat and other organic grains including barley, oats, spelt, and einkorn. That traces can even be found on organic grains seems to indicate that the process of applying glyphosate to grains is widespread.

  6. If you Google “wheat desiccation roundup” the very first article you’ll see listed is the Snopes debunking of the paper referenced and the supposed practices you’re talking about…pseudoscience does NOT serve the ends you’re working toward, which I believe to genuinely be a healthier world/diet — in fact, the more pseudoscience is trotted out in service of this end, the less credible your entire undertaking becomes.

    • Thanks for your comment. I read the Snopes report; however, it did not provide any evidence that the government data were incorrect in the amount of glyphosate being used on wheat in the US. Instead, the report presented many anecdotal reports from farmers who said they did not use glyphosate.

      The health effects of glyphosate are still being debated, but the studies showing glyphosate to be safe were conducted primarily by the biotech companies wanting to sell the product. Also, most, if not all, of those studies were conducted on glyphosate alone and not on the complete product–Roundup is one brand name–as used on agricultural crops. Apparently glyphosate in combination with its adjuvants is more harmful than glyphosate alone.

      Snopes provides an informative service; however, its reports are not always accurate.

  7. Why is Snopes being less then upfront about wheat and Monsanto? Because its number one backer George Soros has just made his second largest investment ever. Care to guess where? That is right Monsanto. He is doing this in an effort to gain control of wheat production. Best way to over throw an economy and a government is not by guns but by food markets. George your on the wrong side of the issue here. Get on the right side and do it now or do not expect credibility in the future with environmentalist. You know how badly you need us as your foot soldiers.

    • I could not find out who invests in Snopes since they are a privately held company; however, I did find support for George Soros’ heavy investment in Monsanto.

      The Wall Street Journal, in an article dated November 16, 2010, says

      The value of billionaire investor George Soros’ hedge fund increased by 31.6% to $6.7 billion at the end of the third quarter compared with the previous quarter, as he boosted his stake in blue-chip stocks AT&T Inc. and Monsanto, according to a regulatory filing late Monday.

      . . .

      Soros also purchased 897,813 shares of Monsanto–his second-largest holding on a dollar basis–during the quarter. The position is now valued at $312.6 million.

      A November 15, 2013, article on Gurufocus says that Soros purchased additional Monsanto stock: “476,170 shares of Monsanto Company (MON), representing 0.54% of his portfolio.”

      • oh….and Hillary Clinton hired a high level former Monsanto exec or paid lobbyist(I’ve forgotten which) to run her campaign. that company has so many deep political puppets it is amazing. Which is why the EPA is so willing to raise the acceptable limits on crops (even the organic ones!!!) We’re doomed. The only way to combat this is with the purse. don’t buy their GMO’s. Buy only organic. And WRITE, WRITE, WRITE (email, tweet, FB) the grocers, the food producers (kraft, frito lay, etc.) and the restaurants that you want to influence. Tell them you won’t buy/shop for their products or in their facilities if they do not make a commitment to organics and non-gmo. If the stuff rots on the shelves unbought they will stop producing it. It is the only way to succeed. Educate your neighbors. Make it one of those email distributions where you ask all recipients to send it to 5 friends. Provide the links to the studies, and write a quick paragraph at the top explaining WHY.

        1) you cannot wash it off, it is systemic in the plants.
        2) serious documented health effects (studies)
        3) GMO is not like hybridization, which is within the same genus/species. They are taking baceterium and viruses and harvesting genes from this part of the animal kingdom and putting it in plants. Bacteria and plants don’t natively cross-breed.
        4) yes labs can tell the difference in unlabeled samples of GMO and non-gmo and organic crops by fat, carb, protein mixes as well as residues.
        5) endocrine disruption happens AT VERY LOW LEVELS of exposure. Well below the acceptable limits.
        6) Europe’s acceptable limits are far below the US. Some European countries have banned the sale of roundup for retail home customers. WHY??? Not because its harmless…
        7) ask them how many kids to they know in their neighborhoods with severe allergies, gluten intolerance, IBS or colitis, migraines, hormonal issues, etc? Does it seem far more prevalent than when they were kids??? YES.
        8) note that glyphosate went off patent in 2000, which yielded huge spike in use due to generic competition, much of which is China, and reduced costs for product.
