Syngenta, a pesticide and genetically-modified seed firm, has inked an outsourcing deal with Infosys, covering all 90 countries of its operations.
Under the deal, Infosys will standardise systems and processes at the Swiss company and operate IT under a single global shared services agreement.
Infosys will also work to plan Syngenta's future business architecture.
Martin Walker, head of business services at Syngenta - which employs 26,000 people - said IT services were "critical to our success and competitiveness" in all markets, across five continents.
Syngenta, which has faced serious controversy over its stance on genetic crop engineering, has agreed to appoint Infosys as preferred bidder on any future business transformation initiatives.
