Bollgard
insect-protected cotton, first commercialized in 1996, uses Bt technology
similar to YieldGard corn to help provide growers with in-plant,
season-long protection against tobacco budworm, bollworm and pink bollworm.
Last year, Bollgard was sold commercially in the United States,
Australia, Mexico, China, Argentina and South Africa.
Following
are highlights from each country in which Bollgard was sold.
Argentina
About 10,000
hectares (24,700 acres) of Bollgard cotton were planted in Argentina
in the 1998/99 season, and, even though the trait was not yet available
in the most appropriate varieties for this country, farmer satisfaction
with the product was rated good to very good. Bollgard growers
in Argentina enjoyed an average profit advantage of $49 per hectare as
compared to conventional cotton. Bollgard increased yields by 10
to 15 percent over conventional cotton, and in some areas reached three
times as much. It's projected that Argentinean farmers possibly could
reduce their insecticide use by three million liters if Bollgard
were available throughout the country.
Australia
Monsanto's
insect-protected cotton is sold under the brand name INGARD in
Australia, where farmers planted 75,000 hectares (185,325 acres) of the
product in the 1998/99 growing season. Grower satisfaction with INGARD
was high, and its use helped to reduce insecticide use in Australia by
44 percent as compared to conventional cotton.
China
As the world's
second most populous developing county, China must increase its agricultural
production on existing acres if it is to meet the demands of its people
for food and fiber. In 1999, a survey of 2,500 growers in 25 countries
revealed that Bollgard cotton provided them an average 25 percent
yield advantage over conventional cotton - an increase worth $80 million
in U.S. currency to China's farmers. In a single province, use of
Bollgard also reduced the volume of chemical insecticides normally
applied to conventional cotton by 850,000 liters.
Mexico
About
500 farmers in Mexico planted 17,368 hectares (42,916 acres) of Bollgard
in 1999. The product helped provide all growers with excellent protection
against insect pests. In fact, 1999 results indicate the use of Bollgard
in Mexico helped to decrease overall insecticide applications in cotton
by 38 percent, while it helped provide farmers with an average 12 percent
yield increase over conventional varieties.
South
Africa
South African
farmers planted 62 percent more Bollgard cotton in 1999 than in
1998, and farmers here recorded yield increases of 7 to 21 percent for
commercial growers and 60 percent for smaller scale farmers. Here, too,
Bollgard is proving to be easy to use and profitable for large
and small farmers alike - an important characteristic of biotechnology
crops indicative of their benefit to developing countries.
United
States
In 1999,
US acres of Bollgard cotton rose from about 2.2 million in 1998
to about 3.7 million last year. Higher yield potential, greater profits
and increased protection against insect damage continue to increase
Bollgard's value for US cotton growers.
As part
of Monsanto's environmental commitment, we continue to monitor Bollgard
fields for insects resistance and have detected none. Insect Resistance
Management (IRM) programs are in place and required by Monsanto and the
Environmental Protection Agency.

Innovations
1999 marked
additional field trials, under an Experimental Use Permit, of Bollgard
II, a second generation product that features two different Bt genes
in the same seed. This combination of genes may help further reduce the
potential development of insect resistance. Field tests have shown Bollgard
II provides improved control of fall armyworm, beet armyworm, cotton
bollworm and soybean loopers. More than 200 field tests of Bollgard
II are planned in the United States, Argentina and Australia.

- 71.2% of
Bollgard growers did not spray for bollworm at all for
the whole season.
- 28.8% of
Bollgard growers sprayed only 1 to 3 times.
- Average spray
times for the Bollgard were 0.72 times.
- Average spray
times for other varieties were 14 times.
