To capitalize on Xanthomonas, the direct play is Corteva Agriscience (NYSE: CTVA), a leading crop-protection and seed company that develops bactericide and disease-management products. Another major exposure is Bayer AG (NYSE: BAYRY, or BAYN on Xetra), whose Crop Science division develops broad-spectrum plant-protection products used to control bacterial diseases; owning Bayer gives indirect access to R&D in Xanthomonas management. For broader exposure, you can pursue sector bets on agriculture inputs or biocontrol developers; entrepreneurial opportunities exist in creating rapid diagnostics, field-ready biocontrols, or farm-management services that help growers monitor and combat Xanthomonas outbreaks.
