AP: ‘Mounting Evidence’ of Bug-Resistant
Corn Seen by EPA
The EPA is finding mounting evidence that Monsanto's GMO-corn strains, designed to produce the pesticide Bt, are producing "superweeds" and
"superworms" that have developed immunity to the pesticide.
“There is mounting evidence raising concerns that insect resistance is developing in parts of the corn belt,” the EPA said Aug. 31 in an
Root worms exposed to the GMO-corn's Bt toxin have become immune to it, breeding colonies of superworms that will spread throughout the Midwest.
“EPA is concerned about the reported resistance to Cry3bB1 in corn rootworm populations in some parts of the country, as are others in the
agricultural community,” the agency said.
Monsanto’s worst resistance problem is with crops engineered to tolerate its Roundup herbicide. “Superweeds” that Roundup no longer kills
have invaded as many as 20 million acres (8.1 million hectares) of corn and soybeans, according to a Dow study. As many as 28 million acres of cotton,
soybean and corn may host Roundup-resistant weeds by 2015, according to Basel, Switzerland-based Syngenta.
The EPA requires farmers of Bt corn to plant a so-called refuge, an area of non-modified corn that grows near the modified crop. The agency reasons
that bugs not exposed to the toxin will then mate with any resistant rootworms, creating a new generation of insects that is once again susceptible to
Well good luck with that strategy - you know you can't mess with Mother Nature like this and have it all go as planned.
Some background information on Bt toxins;
Bt: Miracle Organic Pesticide or Potential Environmental Disaster?
Remember, Monsanto has now released a new sweet corn variety containing the Bt pesticide for sale in groceries, marketed as fresh produce for human
consumption. Monsanto has also fought and won against any labeling laws that would have forced them to disclose GMO crops, so consumers will not know
whether they are buying is GMO or not.
- Increasingly, the types of Bt being used are rare strains that are performance-enhanced or sometimes genetically engineered. The use of Bt
pesticides has spread from farms and occasional homeowner use to the spraying of millions of acres every year around the world, often over large
tracts of forest land or areas with large urban populations.
- The Bt strains being used are applied at rates up to one billion times the natural levels. Often, they wipe out entire families of insects in the
sprayed areas. For instance, Btk, a strain used to control moth pests such as tussock and gypsy moth, kills all insects in the Lepidoptera family
(moths and butterflies). Soil biota is also affected – there is evidence to show that nematodes and predator insects (that would naturally control
the pest population) are depressed also.
- Despite Bt’s purported safety for humans, no long term testing has ever been done to assure its safety. Why should you worry?
- Bt is extremely similar (so much so it is difficult to distinguish without sophisticated testing) to two other bacteria, B. cereus, which
causes food poisoning, and B. anthracis, which causes anthrax.
- Bt secretes many of the same toxins B. cereus does when it is growing. There is mounting evidence that spores germinate in humans and can live for
extended periods of time in the respiratory and gastrointestinal tract. The effect of these low level infections is unknown, but there have been
isolated reports of disease caused by Bt. One of the reasons Bt may not be seen as a common cause of sickness is that it is very hard to test for its
presence – many cases diagnosed as B. cereus gastroenteritis (a fairly common form of food poisoning) may in fact be caused by Bt.
- People with sensitive immune systems could be affected in ways we do not yet know, but immune responses are seen when Bt infections establish in
- DDT was used for thirty years and was claimed to be extremely safe for humans. The same sort of testing done to arrive at that conclusion has been
done with Bt.
- Unfortunately, when Bt pesticides are formulated, a number of “inert” ingredients are added as preservatives, enhancers, and flow and wetting
agents. These inerts are never revealed by manufacturers or tested for safety, and some may be toxic. For instance, Foray 48B, a common moth
insecticide, probably contains the chemical BIT (1,2-benzisothiazolin-3-one) that was recently prohibited for environmental releases in the
In the foolish attempt to tame nature, man will unleash biotoxins that have never been tested on humans, who's long range affects in the natural
environment can scarcely be imagined. 'Superweeds' and 'superworms' will only be the tip of the iceberg.
