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

While visiting a seed corn dealer’s demonstration plots in Iowa last fall, Dr. Don Huber walked past 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. 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.

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.)

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.
"This is the herbicidal mode of action of glyphosate...increases susceptibility to disease, suppresses natural disease controls such as beneficial organisms, and promotes virulence of soilborne pathogens at the same time.” In fact, he points out that “If you apply certain fungicides to weeds, it destroys the herbicidal activity of glyphosate!”

By weakening plants and promoting disease, glyphosate opens the door for lots of problems in the field. According to Don, “There are more than 40 diseases of crop plants that are reported to increase with the use of glyphosate, and that number keeps growing as people recognize the association between glyphosate and disease.”

[NOTE: The point being is that farmers are adversely affecting the food chain having to use GM plants and herbicides that accompany them.]
