Why Monsanto Thought Weeds Would Never Defeat Roundup
EDITED

Why didn't Monsanto's scientists foresee that weeds would become 
resistant to glyphosate, the weed-killing chemical in their Roundup?

In 1993, when Monsanto asked the USDA to approve RR soybeans, it 
dispensed with the issue of potential resistant weeds. It told the 
agency that "glyphosate is considered to be a herbicide with low risk 
for weed resistance."
The company also wrote that several scientists agreed "that it is 
highly unlikely that weed resistance to glyphosate will become a 
problem as a result of the commercialization of glyphosate-tolerant 
soybeans."

Oops. Since then, resistance to glyphosate has emerged in 20 
different weed species.

I called up several Monsanto. Why didn't people there think 
resistance would happen?
The company's scientists had just spent more than a decade, and many 
millions of dollars, trying to create the RR plants that they 
desperately wanted - soybeans and cotton and corn.  Considering how 
hard it had been to create those crops, "the thinking was, it would 
be really difficult for weeds to become tolerant" to Roundup.
