New GMO Crops Tolerant to Monsanto’s Roundup Ready Herbicide Create Conditions for the Development of “Superweeds” | Global Research

New GMO Crops Tolerant to Monsanto’s Roundup Ready Herbicide Create Conditions for the Development of “Superweeds” | Global Research

The crops under consideration were engineered
by Dow AgroSciences, a Dow Chemical Company subsidiary. They’re part of
what Dow calls the Enlist Weed Control System: Enlist, a proprietary
mixture of glyphosate and 2,4-D herbicides, and the plants onto which Enlist can be sprayed without causing them harm as it kills surrounding weeds.


When Roundup Ready crops were first introduced in the 1990s, some
scientists warned that weeds would eventually evolve tolerance to
glyphosate: After all, any herbicide-hardy weed would have an enormous
reproductive advantage. Monsanto said that wouldn’t happen. It did,
sooner rather than later. Such weeds are now an enormous problem,
infesting roughly 75 million acres of fields, an area roughly equivalent
to the size of Arizona.
