The curious collection of a slightly mad scientist
A late-breaking study shows that genetically engineered (GE) crops have led to a 404 million pound increase in overall pesticide use from the time they were introduced in 1996 through 2011. This equates to an increase of about seven percent over the last 16 years.
The report, published in the journal Environmental Sciences Europe,1 effectively undermines the declared value of crops genetically engineered to be protected against herbicides and insects. The whole premise for GE crops was to make it easier to kill weeds and diminish crop loss to harmful pests.
But instead, these modified crops have led to resistance, both in weeds and pests, leaving farmers to struggle with an increasingly difficult situation. More than two dozen weed species are now resistant to glyphosate, the primary ingredient in Monsanto’s broad-spectrum herbicide Roundup.
Things are Rapidly Getting Worse…
According to the author, Charles Benbrook, a research professor at the Center for Sustaining Agriculture and Natural Resources at Washington State University:
“Contrary to often-repeated claims that today’s genetically-engineered crops have, and are reducing pesticide use, the spread of glyphosate-resistant weeds in herbicide-resistant weed management systems has brought about substantial increases in the number and volume of herbicides applied.
If new genetically engineered forms of corn and soybeans tolerant of 2,4-D are approved, the volume of 2,4-D sprayed could drive herbicide usage upward by another approximate 50 percent. The magnitude of increases in herbicide use on herbicide-resistant hectares has dwarfed the reduction in insecticide use on Bt crops over the past 16 years, and will continue to do so for the foreseeable future.”
According to Benbrook, rapidly increasing weed resistance is now driving up the volume of herbicide needed by about 25 percent annually. In a statement to Reuters,2 Benbrook said:
“Things are getting worse, fast. In order to deal with rapidly spreading resistant weeds, farmers are being forced to expand use of older, higher-risk herbicides. To stop corn and cotton insects from developing resistance to Bt, farmers planting Bt crops are being asked to spray the insecticides that Bt corn and cotton were designed to displace.” …
One of those higher-risk chemicals is 2,4-Dichlorophenoxyacetic acid (2,4-D) – one of the ingredients in Agent Orange, which was used to defoliate battle fields in the jungles of Vietnam, with horrendous consequences to the health of those exposed. If you want to see some of its effects on children who were exposed in the womb, you can do so on DigitalJournalist.org3 – but I warn you the photos are very graphic and upsetting.
Benbrook’s paper includes a model showing how a 2,4-D-resistant corn product, if released in 2013, would affect the use of 2,4-D on farm fields. According to his projections, which he refers to as “conservative” assumptions, use of 2,4-D could reach 103.4 million pounds annually as early as 2019 – up from the current level of 3.3 million pounds in 2010.
Due to the toxic nature of 2,4-D, the results of such a massive increase in use would raise risks of birth defects and reproductive problems in those who consume the food, not to mention the severe hazard it poses to aquatic and other ecosystems. This is valuable information indeed, considering the fact that biotech giant Dow’s new GE product, dubbed “Enlist,” is a three-gene, herbicide-tolerant soybean engineered to be resistant to not only glyphosate, but glufosinate and 2,4-D as well!
Talk about a triple whammy of trouble coming down the pike…
Ironically, Dow touts their new product as a solution to Monsanto’s failing Roundup Ready GE crops. This despite the fact that 28 species across 16 plant families have already evolved resistance to herbicides with a similar mode of action as 2,4-D, according to a 2011 article in the Proceedings of the National Academy of Sciences,4 in which the authors criticize speculation that 2,4-D would not cause resistance. Remember that Monsanto recently won a billion dollar award in their suit against Dow. …
