| Sumario: | An optimal control framework is designed inwhich the use of clean plantingmaterials, debudding, disinfection of tools, and roguing
are considered as control measures of Banana Xanthomonas Wilt (BXW) within a plantation of multiple cultivars. A model for a
special case of two cultivars (AAA- and ABB-genome cultivars) was analyzed. By Pontryagin’sMaximumPrinciple, we characterized
and discussed possible control strategies that substantially reduce the infection levels of BXW within a plantation of ABB- and
AAA-genome cultivars. A combination of both prevention and containment controls yielded the greatest decline in the infection
levels in both cultivars. Additionally, for effective BXW management, it is important to assess the endemic level of the plantation
before application of controls, and once implemented, this should bemaintained even when the disease is undetectable to eliminate
possible resurgence
