I'm sure there aren't many who believe Billo when he advocates using
glyphosate as table salt, nor nearly as apt to believe safety statistics
generated by people hired away from Philip Morris to whitewash glyphosate
as tidily as they previously whitewashed cigarettes

I'm not sure it really matters. At the rate that resistance in weeds is
increasing the use of glypohosate may become meaningless in the near future.

"Since genetic engineers devised herbicide-resistant crops in the mid-1990s,
weed killers such as Roundup have become the wonder drugs of the farming
industry, clearing out pest plants while leaving corn and soybeans intact.
But weeds are developing resistance as well. Weed specialist Ian Heap and
his colleagues at the International Survey for Herbicide Resistant Weeds in
Corvallis, Oregon, have found that more than 50 species of
herbicide-tolerant weeds have popped up just since 1995-a trend fueled by
the 2 billion pounds of herbicide farmers dump on their crops every year.
"We're very concerned, because so many soy and corn farmers rely solely on
Roundup for weed control," he says. He is urging farmers to use different
herbicides each year and to invest in old-fashioned methods of weed control,
such as tilling the soil. "
