Overview

Observational analysis reveals 100% anthracnose incidence in banana plants, indicating a significant threat to local production.

Key Points

  • Necrotic lesions indicative of anthracnose were observed on Dwarf Cavendish bananas, affecting nearly all leaves and rendering some fruits unmarketable.
  • Disease incidence reached 100%, with over 50% leaf infection per plant in Dwarf Cavendish varieties.
  • Isolates were identified as C. siamense through gene sequencing and phylogenetic analysis, fulfilling Koch’s postulates during pathogenicity testing.
  • This finding highlights an urgent need for an integrated management approach to mitigate this threat to banana production in Mauritius.
