MONSANTO AND SUMITOMO CHEMICAL ENTER NEW GLOBAL CROP PROTECTION
COLLABORATION FOR NEXT GENERATION PPO TECHNOLOGIES

ST. LOUIS (June 27, 2016) – Monsanto Company and Sumitomo Chemical Company, Ltd. today
announced a new global agreement that will focus on developing and delivering next-generation weed
control solutions to further help growers manage tough-to-control weeds.
Monsanto has a robust pipeline of multi-generational herbicide trait upgrades in its research anddevelopment pipeline that are designed to provide multiple and additional modes of action for weed
control well into the future. This includes PPO-herbicide tolerance traits, which are in the early phases ofresearch and development and are expected to be included in Monsanto’s future generation multiherbicide tolerant trait stacks. In addition to its existing portfolio, Sumitomo Chemical has beendeveloping a new generation PPO chemistry that has shown broader spectrum control with application
flexibility that has the potential to enhance current and future weed control systems.
Under the new global agreement, Monsanto and Sumitomo Chemical will work together and inparallel to create an integrated system of germplasm, biotechnology and crop protection that willrepresent this new generation of weed control solutions. As part of this, Monsanto and Sumitomo
Chemical will collaborate in the development, registration and commercialization of Sumitomo
Chemical’s key PPO chemistries including its new generation PPO herbicide for over-the-top andconventional herbicide application use in Monsanto’s future generation weed management systems, aswell as conventional applications for certain other crop uses. The new generation PPO herbicide isexpected to be available within brands offered by both companies. By working in parallel to develop
multiple aspects of this enhanced weed control solutions that has the potential to benefit all major global
field crops, the agreement will leverage both companies’ capabilities, including Monsanto's strength inintegrated field testing and development. The next-generation herbicide is expected to be commerciallyavailable early in the next decade, pending regulatory approvals. Additional details of the agreement werenot disclosed.
“I’m really excited about Sumitomo Chemical’s next generation weed control technology,” said
Robb Fraley, Monsanto Executive Vice President and Chief Technology Officer. “This next-generation
PPO herbicide has remarkable broad spectrum effect against both grass and broadleaf weeds, which will
make it an excellent, complementary addition to the Roundup Ready® platform. The product’s low use

rate, together with a unique mode of action effective against resistant PPO weeds, will be valuable to corn,
soy and cotton growers.”
Ray Nishimoto, Sumitomo Chemical Representative Director & Senior Managing ExecutiveOfficer, President of Health & Crop Sciences Sector, said, “This collaboration combines the strength ofMonsanto to discover and develop herbicide tolerance traits with Sumitomo Chemical's world-classdiscovery program for new crop protection products that are highly effective for sustainable weedmanagement.”
This announcement builds on the strong collaboration the two companies have had for many
years through the Roundup Ready PLUS® Crop Management platform to bring farmers the bestperforming herbicide solutions to manage tough and resistant weeds.
