Round-up resistant weeds

Leave a comment

The NY Times (via Cornucopia Institute) today had a story about Round-up resistant weeds:

“It is the single largest threat to production agriculture that we have ever seen,” said Andrew Wargo III, the president of the Arkansas Association of Conservation Districts.

There is one [small] positive aspect to this:

The superweeds could temper American agriculture’s enthusiasm for some genetically modified crops. Soybeans, corn and cotton that are engineered to survive spraying with Roundup have become standard in American fields. However, if Roundup doesn’t kill the weeds, farmers have little incentive to spend the extra money for the special seeds.

Fortunately for now, the problem does not appear to be widespread.  But we all know how evolution works, and our current factory-scale agriculture is contributing to a faster-than-normal evolving of weeds, bugs, and other problems that people have been dealing with for millennia.  And the main problem with that is: we’re creating problems faster than we can solve them.

Anyway, here’s the article on Round-up resistant weeds.

Update, 5 May 2010: Marion Nestle of the excellent blog Food Politics explains the science of how weeds become resistant to glyphosate (Round-up).
