Pioneer annouces Canadian approval of new insecticide

Jan. 5, 2012, Chatham, ON – Pioneer Hi-Bred, a DuPont business, has received
Canadian Food Inspection Agency (CFIA) approval of Optimum AcreMax
XTreme insect protection, which integrates all of a corn grower’s above- and
below-ground insect control and refuge needs in a single bag. Optimum AcreMax
XTreme products will be introduced into the Canadian market in the 2013
planting season.

“Pioneer brand seed corn is planted on twice as
many acres than any other brand in Canada. With Optimum AcreMax XTreme products
we are expanding upon our leadership position in the corn market,” says Ian
Grant, president and business director of Pioneer Hi-Bred Ltd. “Optimum AcreMax
XTreme products incorporate above-and below-ground insect protection with
required refuge, maximizing productivity and yields for corn growers with these
needs.”

Optimum AcreMax XTreme products integrate 95
percent of a trusted Pioneer brand corn hybrid containing Herculex XTRA
(HXX) insect protection pyramided with YieldGard Corn Borer (YGCB) insect
protection and the AgriSure® RW (ASRW) trait and 5 percent of a similar non-Bt
hybrid with herbicide tolerance to serve as the integrated refuge.  All Optimum AcreMax XTreme products
offer built-in glyphosate and Liberty herbicide resistance.

This season, Pioneer will strategically plant
Optimum AcreMax XTreme product research trials across a wide geographic region
so that farmers can assess product performance firsthand and in advance of the
2013 growing season.

Optimum AcreMax XTreme products will be offered in
addition to the already available single-bag Optimum AcreMax above-ground
insect protection and refuge product line. Pioneer launched a wide-scale of
maturities of Optimum AcreMax products for the 2012 planting season covering
most of the corn-growing regions across Eastern Canada.

Growers who plant Optimum AcreMax and Optimum
AcreMax XTreme products will be in compliance with refuge requirements as set
forth by the CFIA.

Registration documents for
Optimum AcreMax XTreme products are currently under review at the U.S.
Environmental Protection Agency (EPA).
Pioneer anticipates a decision regarding Optimum AcreMax XTreme products
from the U.S. EPA in time for 2013 spring planting.
