Reasons for the Separation and Distribution, page 52

3.       You state here reasons for the separation include, among other
reasons, creating a focused
         business, tailored growth strategies, sharper focus on core business,
and the ability of
         management to implement strategies tailored to each company's specific
business
         characteristics. Please describe the most significant differences in
strategy, operating
         priorities, and business focus between Corteva and DowDuPont prior to
the separation.
4.       In the first bullet point on page 53, please briefly discuss Corteva's
capital allocation
         needs and how its capital structure will facilitate meeting these
needs.

Operations
Recent Developments, page 91

5.       We note your disclosure that certain events and circumstances in 2018
along with a
         reduction in cash flow projections caused a triggering event that
required Historical
         DuPont to perform an impairment analysis of its agriculture reporting
unit's goodwill and
         indefinite-lived intangible assets as of September 30, 2018, and that
as a result, Historical
         DuPont recorded pre-tax (and after-tax), non-cash impairment charges
of about $4.5
         billion for goodwill and $0.1 billion for certain indefinite-lived
assets associated with its
         agriculture reporting unit. Please tell us the significant assumptions
Historical DuPont
         used to determine the estimated fair value of its agriculture
reporting unit during the
         quarter ended September 30, 2018 and more fully explain the facts and
circumstances that
         resulted in these impairments to be recorded during this interim
period.
DowDuPont Cost Synergy Program, page 93

6.       Please provide context for the Cost Synergy Program by discussing and
quantifying, to the
         extent you are able, the potential loss of synergies and one-time
costs associated with the
         separation.
7.       In the second paragraph of this subsection, please disclose the amount
of the cost synergy
         commitment attributable to Historical DuPont.
