The proliferation of superweeds -- weeds that
have mutated to develop resistance to popular herbicides
like Monsanto's Roundup formula -- continues to rise.
But the individual plants' overall size and strength is
also increasing. According to a series of new studies
published in the journal Weed Science, farmers are
having more trouble than ever dealing with
out-of-control superweeds in their fields, some of which
grow up to three inches a day in size, and are so strong
and thick that they are destroying farm equipment.
The studies reveal that there are currently at
least 21 different weed species known to be resistant to
Roundup, also known generically as glyphosate. These
species include ragweed, pigweed, horseweed, waterhemp,
and ryegrass. Since 2007, the total acreage of
farmland known to be infested with superweeds has also
jumped more than 450 percent, from 2.4
million acres to 11 million acres, which means that the
problem is only going to
get exponentially worse.
"Super-strains of plants like pigweed -- which
grows three inches a day and is tough enough to damage
farm machinery -- have emerged, which may dramatically
reduce the options for farmers to control them," writes
Fast Company in a recent piece on the issue. "The
alternatives are usually more dangerous chemicals or
plowing and mulching fields, undermining many of the
environmental benefits biotech crops are supposed to
offer. It's 'the single largest threat to
production agriculture that we have ever seen,'
claims Andrew Wargo III, president of the Arkansas
Association of Conservation Districts."
