Monsanto's Roundup Triggers Over 40 Plant Diseases and Endangers Human and Animal Health

The following article reveals the devastating and unprecedented impact that Monsanto's Roundup herbicide is having on the health of our soil, plants, animals, and human population.

On top of this perfect storm, the USDA now wants to approve Roundup Ready alfalfa, which will exacerbate this calamity.

While visiting a seed corn dealer's demonstration plots in Iowa last fall, Dr. Don Huber walked passed a soybean field and noticed a distinct line separating severely diseased yellowing soybeans on the right from healthy green plants on the left (see photo).

The yellow section was suffering from Sudden Death Syndrome (SDS), a serious plant disease that ravaged the Midwest in 2009 and '10, driving down yields and profits. Something had caused that area of soybeans to be highly susceptible and Don had a good idea what it was.
Don Huber spent 35 years as a plant pathologist at Purdue University and knows a lot about what causes green plants to turn yellow and die prematurely. He asked the seed dealer why the SDS was so severe in the one area of the field and not the other. "Did you plant something there last year that wasn't planted in the rest of the field?" he asked. Sure enough, precisely where the severe SDS was, the dealer had grown alfalfa, which he later killed off at the end of the season by spraying a glyphosate-based herbicide (such as Roundup). The healthy part of the field, on the other hand, had been planted to sweet corn and hadn't received glyphosate.

This was yet another confirmation that Roundup was triggering SDS. In many fields, the evidence is even more obvious. The disease was most severe at the ends of rows where the herbicide applicator looped back to make another pass (see photo). That's where extra Roundup was applied.
Don's a scientist; it takes more than a few photos for him to draw conclusions. But Don's got more--lots more. For over 20 years, Don studied Roundup's active ingredient glyphosate. He's one of the world's experts. And he can rattle off study after study that eliminate any doubt that glyphosate is contributing not only to the huge increase in SDS, but to the outbreak of numerous other diseases.

Roundup: The perfect storm for plant disease

More than 30% of all herbicides sprayed anywhere contain glyphosate--the world's bestselling weed killer. It was patented by Monsanto for use in their Roundup brand, which became more popular when they introduced "Roundup Ready" crops starting in 1996. These genetically modified (GM) plants, which now include soy, corn, cotton, canola, and sugar beets, have inserted genetic material from viruses and bacteria that allows the crops to withstand applications of normally deadly Roundup.

(Monsanto incentivizes farmers who buy Roundup Ready seeds to also use the company's Roundup brand of glyphosate. For example, they only provide warranties on the approved herbicide brands and offer discounts through their "Roundup Rewards" program. This has extended the company's grip on the glyphosate market, even after its patent expired in 2000.)

The herbicide doesn't destroy plants directly. It rather cooks up a unique perfect storm of conditions that revs up disease-causing organisms in the soil, and at the same time wipes out plant defenses against those diseases. The mechanisms are well-documented but rarely cited.
The glyphosate molecule grabs vital nutrients and doesn't let them go. This process is called chelation and was actually the original property for which glyphosate was patented in 1964. It was only 10 years later that it was patented as an herbicide. When applied to crops, it deprives them of vital minerals necessary for healthy plant function--especially for resisting serious soilborne diseases. The importance of minerals for protecting against disease is well established. In fact, mineral availability was the single most important measurement used by several famous plant breeders to identify disease-resistant varieties.

Glyphosate annihilates beneficial soil organisms, such as Pseudomonas and Bacillus bacteria that live around the roots. Since they facilitate the uptake of plant nutrients and suppress disease-causing organisms, their untimely deaths means the plant gets even weaker and the pathogens even stronger.

The herbicide can interfere with photosynthesis, reduce water use efficiency, lower lignin, damage and shorten root systems, cause plants to release important sugars, and change soil pH--all of which can negatively affect crop health.

Glyphosate itself is slightly toxic to plants. It also breaks down slowly in soil to form another chemical called AMPA (aminomethylphosphonic acid) which is also toxic. But even the combined toxic effects of glyphosate and AMPA are not sufficient on their own to kill plants. It has been demonstrated numerous times since 1984 that when glyphosate is applied in sterile soil, the plant may be slightly stunted, but it isn't killed
