Monsanto (NYSE: MON) Chief Operating Officer Brett Begemann said the company is considering whether to begin another attempt to buy Syngenta (NYSE: SYT).

“Monsanto could launch a takeover offer at any point” for Syngenta, Martin Schreiber, analyst at Zuercher Kantonalbank, told Bloomberg. “A merger between Dow and DuPont could put Syngenta in a bind.”

Monsanto shares were 0.4% lower Tuesday while Syngenta shares advanced 7.3%.
