‘Roundup’ resistant weeds pose environmental threat

Jun 25th, 2010 | By | Category: Health

CHAMPAIGN, Ill. — When the weed killer Roundup was introduced in the 1970s, it proved it could kill nearly any plant while still being safer than many other herbicides, and it allowed farmers to give up harsher chemicals and reduce tilling that can contribute to erosion.

But 34 years later, a few sturdy species of weed resistant to Roundup have evolved, forcing farmers to return to some of the less environmentally safe practices they abandoned decades ago.
