A comprehensive carcinogenicity study on the world's most used herbicide, glyphosate, involving scientists from Europe and the U.S., has found that low doses of the controversial weed killer cause multiple types of cancer in rats.
In this long-term study, glyphosate alone and two commercial glyphosate-based formulations, Roundup BioFlow used in the EU and Ranger Pro used in the U.S., were administered to rats via drinking water beginning in prenatal life, at doses of 0.5, 5, and 50 mg/kg body weight/day for 2 years.
These doses are currently considered safe by regulatory agencies and correspond to the EU Acceptable Daily Intake (ADI) and the EU's No Observed Adverse Effect Level (NOAEL) for glyphosate.
In all three treatment groups, increased incidences of benign and malignant tumors at multiple anatomic sites were observed compared to controls. These tumors arose in hemolymphoreticular tissues (leukemia), skin, liver, thyroid, nervous system, ovary, mammary gland, adrenal glands, kidney, urinary bladder, bone, endocrine pancreas, uterus and spleen (hemangiosarcoma).
Increased incidences occurred in both sexes. Most of these involved tumors that are rare in Sprague Dawley rats (background incidence < 1%) with 40% of leukemias deaths in the treated groups occurring in early life and increased early deaths were also observed for other solid tumors.
"We observed early onset and early mortality for a number of rare malignant cancers, including leukemia, liver, ovary and nervous system tumors. Notably, approximately half of the deaths from leukemia seen in the glyphosate and GBHs treatment groups occurred at less than one year of age, comparable to less than 35–40 years of age in humans.
"By contrast, no case of leukemia was observed in the first year of age in more than 1,600 Sprague Dawley historical controls in carcinogenicity studies conducted by the National Toxicology Program (NTP)," stated Dr. Daniele Mandrioli.

“Without glyphosate, crop yields will be a fraction of what they are now.”
At some point one of the developed countries (hopefully not the US) will do what Sri Lanka did when they converted from manufactured fertilizer to ‘organic’ fertilizer...and quickly found half their people about to starve to death, until other countries sent them emergency food shipments.
Developed societies have to make TOUGH CHOICES these days because 8 Billion people cannot be fed using ‘organic’ means...the number is closer to 2 Billion that could be handled that way.
As for myself, I just eat meat, so I don’t have to worry as much as to what’s sprayed on the crops, as the cows hopefully protect me!
We always used newspaper covered with hay
i try, but it’s very hard to avoid glyphosated foods.
—
glyphosate dissipates in 72 hours - all reputable studies [ and this is not one of them ] have found no interaction between glyphosate and humans; glyphosate targets plant genes - so as long as you do not have plant genes, it is harmless.
there is no money in using natural strategies to control weeds and whatever.
—
It not the money - there are no commercially viable natural compound that kills all varieties of weeds [ a weed bring any unwanted plant ].
Put your weeds in a barrel and light on fire and then feed the carbon back into your soil.
—
Residential use of glyphosate is a small fraction of its use.
Weeds in crop fields if not treated will significantly impact the ability of the crops to get nutrients - and so yes, without glyphosate crop yields will drop significantly.
“Soil incorporated pre-emergence weed killers do an effective job when applied to tilled soil.”
Which often contain glyphosate, when they work at all - they need years and years of application to be effective, since pre-emergence are cumulative.
Same with non organic wheat from what I have been told
On all the other days that are not hot and sunny, the weeds eat the nutrients in the soil, robbing your beneficial plants of food.
Thanks...some sanity
We have actually killed poison oak by piling leaves on it (side of road)...other places we have to spray crossbow.
I got out of farming in the winter of 2000-01, and became a truck driver, so things have changed a lot since then. However, from 2009 through 2011 I was the ‘farmer’ for a family owned corn and soybean seed company (which included being a truck driver for them).
The production manager told what the biggest genetic changes were for corn: the upright leaves, and improved drought resistance and nutrient uptake.
I asked about the fungicide usage. He said that the elimination of moldboard plow usage was leaving more trash on the surface, causing more fungus growth. That, coupled with the increased populations, shade the ground more, which increases the favorable fungus environment. (They used a disc-chisel plow on everthing, except on some of the previous year’s soybean ground, which we no-tilled.)
A study in 2019 at the Bayer test farm near Monmouth, IL, and mentioned the big reasons for increased corn yields, three of which I mentioned, but also ear plasticity allowing better kernel development. (I lived about 20 north of there until 2016)
What I fear is if the petrochemical industry gets clobbered in a war, there will be a desperate need for moldboard plows and rowcrop cultivators. But only if there is fuel still available. Only the Amish and preppers are ready for such a scenario.
I used pre-emerge weed killers, incorporated into the top 2” of the soil with a disc/harrow, for almost 30 years, none with glyphosate. I had very good results.
SEVEN milligrams per liter
—
Glyphosate is usually represented as a percentage of the volume. Not in milligrams - which is a weight measurement and has nothing to do with volume. You do not spray milligrams, you spray volume:
one liter is only 0.26 of a gallon; 7mg is 0.00025 oz; 1 gallon = 3.7 liters
1 gallon of Roundup “Ready to Use” contains 26 milligrams of glyphosate in solution. Or 0.0009 oz of glyphosate, a very weak solution - commercial spraying uses 3 oz a gallon and achieves visible results within 20 minutes. Its probably so weak because the spray nozzle is cheap and the sprayers are untrained home owners, prone to over-spray, nor aware of the wind, and may even step in the fresh spray. Which is why the label usually say not to expect results for a number of weeks.

Hummmmm? Is the lesson here not to put Round Up in your drinking water?
“Yes, glyphosate is the main active ingredient in Roundup”
“My cat ate some grass and it cost me $800 tp save her life. “\
cat livers have limited ability to metabolize pretty much anything but meat-based compounds as all cats are obligate carnivores ... aspirin, tylenlol, xylitol, and hundreds of other chemicals that humans can safely consume will kill a cat ... never let a cat outside for a few days after ANY pesticides or herbicides have been sprayed ...
“Unfortunately, there is no money in using natural strategies to control weeds and whatever.”
from a practical and economic standpoint, it’s impossible to apply “natural strategies” of weed control to billions of acres of farmland worldwide ...

“How close is Roundup to Agent Orange, chemically speaking?”
chemically speaking, they’re both organic chemicals, made up of carbon, oxygen, nitrogen, hydrogen, and an atom of phosphorous [glysophate] or an atom of chlorine (agent orange] ...
agent orange is nothing more than orange colorant mixed with the weed killer 2,4,D which has been in use since 1923 ... 2,4,D kills only broad leaf plants, and is an analog of auxin, which is a natural plant growth hormone ... 2,4,D induces a plant to grow itself to death ...
chemically speaking, no relationship between glysophate and agent orange ...
“It’s always about money.”
