Brazil is the only country in the Americas prepared to face the most severe form of Fusarium wilt, tropical race 4 (TR4). The confirmation came from research by Embrapa conducted in Colombia that proved the resistance of the cultivars BRS Princesa and BRS Platina to this pathogen. The discovery paves the way for the use of these varieties as natural barriers against the spread of the disease on a global scale. Endemic in all banana-producing regions, Fusarium wilt causes billions of dollars in losses by contaminating crops and imposing restrictions on exports.
