The head of Bayer’s crop science division will leave the company at the end of the year following disappointing results in the division’s revenues. Reuters reports that Liam Condon has submitted his resignation, to take effect December 31st. Condon and his boss, Bayer CEO Werner Baumann, oversaw the $63-billion acquisition of Monsanto in 2018, but the German chemical giant was quickly burdened with a series of lawsuits alleging that Monsanto’s signature herbicide Roundup causes cancer. Bayer also posted disappointing earnings for its crop science division this year amid rising raw material costs, even as the company’s overall earnings increased. While Baumann received a contract extension last year, Condon will leave the company to pursue other opportunities. Chief Operating Officer Rodrigo Santos will take over as head of the crop science division.
