- Enlist E3™ Soybeans Headline One of Largest Soybean Technology System Launches Ever

- High-yield Potential Qrome® Products with Triple-stack Insect Control Available Across Corn Belt

-Technologies Authorized by China for Import

WILMINGTON,Deleware,Jan. 18,2019 --Corteva Agriscience™,Agriculture Division of DowDuPont (NYSE: DWDP),today announced plans for commercial launches of Enlist E3™ soybeans in Brazil,Canada and the United States,beginning in 2019. The Company also announced plans to expand the launch of Qrome® products across the U.S. Corn Belt.

"I am excited to announce one of the largest soybean technology system launches ever," said Corteva Agriscience Chief Executive Officer,James C. Collins,Jr. "Enlist E3™ soybeans incorporate advanced herbicide tolerance through three modes of action and enable use of our proprietary Enlist One™ and Enlist Duo® herbicides to provide more complete solutions to farmers."

"We are also announcing expanded availability of Qrome® products across a wider geography,and to more customers," said Collins. "Qrome® hybrids have earned the trust of American producers for consistent performance and have produced high yields by combining top-tier genetics,strong defensive traits and advanced seed treatments."

Enlist E3™ soybeans and Qrome® corn products are among more than 20 new technologies that Corteva Agriscience plans to launch by 20211. They are a key part of the Corteva Agriscience strategy to grow and to drive customer and shareholder value through the Company's combined seed and crop protection pipeline.

Enlist E3™ soybeans were jointly developed by Dow AgroSciences and MS Technologies. Both Enlist E3™ soybeans and grain produced from Qrome® corn products received import authorization from China in January 2019.

Enlist E3™ Soybeans

Enlist E3™ soybeans will be offered in Brazil,Canada and the U.S. across all Corteva Agriscience seed brands. Commercial sales will begin in 2019; timing will vary by country. First-half 2019 activities will focus on expanding grower experiences with Enlist E3™ soybeans through demonstration plots,field technology days and other opportunities. Second-half 2019 activities will focus on commercial sales efforts. Robust ramp-up plans and extensive seed production will ensure that Enlist E3™ soybeans are broadly available to farmers in 2020.

Corteva Agriscience is also engaged with numerous potential seed trait licensees and intends to broadly license Enlist E3™ soybean technology. This will enable farmers around the world to have broader choice and flexibility in selecting herbicide tolerance traits,genetics and crop protection solutions.

"Enlist E3™ soybeans are industry-leading triple-stack herbicide tolerant soybeans that allow Corteva Agriscience to better serve farmers with complementary seed and crop protection products," said Collins. "The fully-enabled launch of Enlist E3™ soybeans follows the successful introduction of top performing Enlist™ cotton varieties and Enlist™ corn hybrids in 2017 and 2018,respectively."

The Enlist E3™ soybean trait provides tolerance to new 2,4-D choline in Enlist Duo® and Enlist One™ herbicides,as well as glyphosate and glufosinate herbicides. Enlist Duo® herbicide is a combination of new 2,4-D choline and glyphosate,a convenient blend for control of tough broadleaf and grass weeds. Enlist One™ herbicide is a 2,4-D choline product offering the same excellent broadleaf weed control with greater tank-mix flexibility,including the ability to tank mix with qualified glufosinate products.

Growers can apply Enlist™ herbicides post-emergence to Enlist E3™ soybeans to help control glyphosate-resistant weeds; additional tolerance to glufosinate means they can utilize three post-emergence herbicide modes of action in Enlist E3™ soybean fields. With near-zero volatility and reduced potential for physical drift,Enlist™ herbicides with Colex-D® technology are designed to land and stay on target.

Qrome® Product Technology

Introductory quantities of Qrome® products will be available in the Pioneer® brand for 2019 planting across expanded geographies in the U.S. Corn Belt. For the 2020 growing season,Qrome® products are planned across a wide range of genetic platforms and maturities in Corteva Agriscience™ seed brands.Farmers who planted Pioneer® brand Qrome® products as part of limited launch in 2017 and 2018 across the Western U.S. Corn Belt reported strong performance and high yields.

"Qrome® products are the most optimized balance of insect protection and agronomic performance in the Corteva Agriscience product portfolio," said Collins.

Qrome® products feature a novel molecular stack of multiple insect protection traits and include two modes of action to control corn rootworm. Pioneer® brand Qrome® products have consistently delivered an average 5.5 bushel yield advantage over legacy triple-stack technology in multi-year research trials. In 2018 on-farm trials,Qrome® products held an average 10.2 bushel per acre advantage over all competitive products tested2.

Enlist E3™ soybeans are approved for cultivation in the U.S.,Canada and Brazil. Qrome® products are approved for cultivation in the U.S. and Canada. Both Enlist E3™ soybeans and grain produced from Qrome® corn products have received import authorization in many importing countries,most recently in China.
