Bt cotton
The letters "Bt" stand for Bacillus thuringiensis, a toxin-producing bacterium found naturally in soils. Scientists have isolated certain genes responsible for the production of these toxins and have then used genetic engineering techniques to insert them into cotton. The resulting cotton plants produce the Bt toxins and susceptible pests die when they eat them. In 2002, Bt cotton was cultivated on 4.6 million hectares around the world, roughly 13% of the total cotton acreage. Almost the entire global acreage of Bt cotton is currently sown to Monsanto's "Bollgard" variety. This company has developed a second Bt cotton variety, "Bollgard II", which produces two different toxins. In 2004, Dow Agro-sciences plans to introduce "Widestrike", another Bt cotton producing two toxins, while Syngenta is trying to introduce its Bt cotton, "VIP Cotton". Bt cotton is a critical technology in the biotech industry's efforts to push GM agriculture around the world.

Tarnishing Silver Bullets: Bt Technology Adoption, Bounded Rationality and the Outbreak of Secondary Pest Infestations in China
"Seven years after the initial commercialization of Bt
cotton in China, we show that total pesticide expenditure
for Bt cotton farmers in China is nearly equal to that of
their conventional counterparts, about $101 per hectare. Bt
farmers in 2004 on the average, have to spray pesticide
18.22 times, which are more than 3 times higher compared
with 6 times pesticide spray in 1999. Detailed information
on pesticide expenditures reveals that, though Bt farmers
saved 46% Bollworm pesticide relative to non-Bt farmers,
they spend 40% more on pesticides designed to kill an
emerging secondary pest. These secondary pests (one example
is Mirid) was rarely found in the field prior to the
adoption of Bt cotton, presumably kept in check by bollworm
populations and regular pesticide spraying. The extra
expenditure needed to control secondary pests nearly offsets
the savings on primary pesticide frequently cited in the
current literature."

Bruce Bond: High Cotton Winner
This award winning US cotton farmer is not satisfied with Bt
cotton and plans to plant more of his acreage to non-Bt
varieties in the future. According to farmer Bruce Bond:
"Secondary pests — plant bugs and stink bugs — are
eating our lunch. I probably have $90 an acre in insecticide
costs on Bt cotton. I think that’s too much, especially when
I pay $32 right up front. Next year, I’d like to bump the
non-Bt cotton acreage up a bit. I planted my refuge cotton
on the worst ground I have, and one 23-acre field of it was
some of the best cotton I picked this year.”
