GC-MS metabolite profiling of Pseudocercospora fijiensis isolates resistant to thiabendazole.

ABSTRACT: Black Sigatoka is the most widespread banana disease worldwide. It is caused by Pseudocercospora fijiensis, a fungal pathogen known for developing resistance to fungicides such as thiabendazole. Despite the increasing costs associated with the use of chemicals to control this disease, the pathogen's mechanisms for fungicide resistance are not fully understood. The metabolite profiles of P. fijiensis isolates with different levels of resistance to thiabendazole were characterized by GC-MS. A total of 33 isolates were obtained from symptomatic banana plants and the sensitivity of each isolate to thiabendazole was assessed at 0, 1, 10, 100, 1000, and 10000 μg.mL-1. Then, the metabolite profile of each isolate was assessed using GC-MS. Metabolites such as hexadecanoic acid, tetradecanoic acid,
