Amazonian cocoa has a new edge: Two standout cultivars could change how growers fight witches' broom

Phys · · 838 words · By FAPESP

A study published in Scientific Reports identifies two cocoa cultivars, EEOP 63 and EEOP 65, that show higher productivity and resistance to witches' broom disease in the Amazon. The research suggests that combining genetic improvement with balanced nutritional management can reduce the reliance on fungicides and fertilizers.
