Transgenic
insect-protected corn is enabling farmers in Spain to
successfully manage against the damage from the European
corn borer, which causes annual yield losses of 5 to 15
percent. The corn borer feeds on all above-ground corn
tissue and tunnels into the tassel, ear, shank and stalk
of the corn plant, interfering with plant growth and
causing stalks to break and ears to drop.
More than half of the
corn grown in Spain is produced in regions with medium
or high annual corn borer pressure. "When the corn borer
attacked strongly … as happened two years ago, the
losses were up to 40 or 50 percent," says Miguel Arazo,
who has farmed for more than 28 years and currently
grows corn and barley on 300 acres (120 hectares).
"In a few hectares, we
collected 34 metric tons of fallen corncobs by hand.
That is unacceptable. So last year, I planted 80 percent
transgenic," comments Arazo in an
exclusive video and podcast available at the
Conversations about Plant Biotechnology Web
site:
www.monsanto.com/biotech-gmo/. "Even when
there are no borer attacks you get 7 or 8 percent higher
yields with transgenics. That's an increase of many
kilos."
Lepidopteran pests such as the corn borer are a major
constraint to increased productivity, and are of
economic importance in most maize-growing countries
throughout the world. Insect-protected transgenic corn
produces a protein from Bacillus thuringiensis (Bt),
which protects plants from specific lepidopteron insect
pests. In 2005, farmers in five European Union countries
grew modest areas of transgenic corn including the Czech
Republic, France, Germany, Portugal and Spain.
"I believe Bt
corn is better for the environment," continues Arazo.
"In this region, non- Bt traditional corn has
to be sprayed with insecticide two or three times, but
there is no need to spray Bt corn at all." In
addition to Arazo's video, visitors to the
Conversations about Plant Biotechnology Web site
can view conversations with two of his fellow Spanish
farmers —
Pedro Lerín and
Ismael Purroy.
Conversations about
Plant Biotechnology is designed to give a voice and
a face to the
farmers and families
who grow biotech crops and the
experts who research
and study the technology. The Web site
contains more than 40, two- to three-minute, extremely
candid, straightforward and compelling video segments
with the people who know the technology best. The Web
site is hosted by Monsanto Company — a leading global
provider of technology-based solutions and agricultural
products that improve farm productivity and food
quality.
