Purdue Professor Dr. Don Huber on Glyphosate and Fusarium Growth



By Lisa Petrison, Ph.D.

The many negative effects of the chemical herbicide glyphosate on the environment as well as on human and animal health were discussed in an in-depth Bulletproof interview with Professor Don Huber of Purdue University.

Dr. Huber is a professor emeritus of agriculture specializing in botany and plant pathology at Purdue. He has a large number of published peer-reviewed journal articles on the subject to his credit.

Among the topics discussed in the Dave Asprey interview was the ability of glyphosate to kill off a wide variety of beneficial microorganisms in the soil, thus allowing the toxic mold Fusarium to grow in an unchecked manner.

Like Stachybotrys mold, Fusarium makes trichothecene toxins that have a wide variety of negative effects on the health of humans and other mammals.

As a result of glyphosate usage, these toxins end up in the outdoor air (where they may negatively effect the health of mold-sensitized individuals) as well as in the food supply.

In the Bulletproof interview, Dr. Huber stated with regard to glyphosate:

“It is a very powerful natural antibiotic. The first thing that it does is eliminate your natural biological controls. A lot of organisms in the environment would suppress our toxin-forming fungi – especially your Fusarium and Aspergillus, two of the big ones. There are number of others that fit in there, but certainly when you remove those natural controls and then provide an environment physiologically for those organisms to flourish, you’ll see the toxin production greatly increase.

“When we’ve looked at the Fusarium toxins, for instance, in corn and wheat and barley, that we used to always look for – zearalenone and deoxynivalenol and the T-1 type toxins. Because in the North American environment, we didn’t have an environment that was conducive for the T-2 toxins that were used in Cambodia against the among people at the Yellow Rain type toxin.

“We could trace the source of those toxins back to regions which had the environment where they could be produced and so made it easy to distinguish between the two toxins. Now with the extensive use of glyphosate, we find a dramatic increase in T-2 toxin production.

“And not only that, in cereal grains and small grains, wheat and barley for instance, we used to only see the toxin really produced in the grain. We didn’t see it in the root system even though we had extensive root colonization.

“If you look at Andreas Tiedemann’s research, he reported at the national Fusarium head blight conference couple years ago, he said it’s not safe to even use a straw or stubble for bedding now, for our pigs and cattle because those toxins are produced in the roots and trans-located up.

“It means that you can have very healthy-looking grain that will have high concentrations of the mycotoxins in them. And then if you use the straw, that you can end up with infertility because it zearalenone is an estrogenic-type compound. So you see all of the other consequences that a very simple molecule can change.”

Dave Asprey summarized:

“What we did is we sprayed the antibiotic on the soil, we removed healthy soil bacteria that allowed the hostile soil fungus to grow out of balance and to colonize parts of the plants. So now very potent fake estrogens, xenoestrogens like zearalenone, are forming in our crops. And then the crop looks healthy but it’s full of toxins and then you eat it.”

The abundance of Fusarium toxins in the Roundup-treated soil is of particular concern to those who are hypersensitized to mycotoxins because it makes agricultural areas particularly difficult for them for them to live in or visit.
