Overview

Field survey and pathogenicity study confirms Lasiodiplodia theobromae causing leaf blight in Coffea canephora, highlighting an emerging fungal threat to Philippine coffee production.

Key Points

  • Necrotic lesions on Coffea canephora were confirmed as leaf blight caused by Lasiodiplodia theobromae, representing its first global identification on robusta coffee trees.
  • Surveys recorded 100% disease incidence across examined trees, with necrotic lesions covering 43% of leaf surface area in the surveyed robusta coffee orchard.
  • Pathogenicity test assays and rDNA ITS region sequencing confirmed the fungal identity, satisfying Koch's postulates and highlighting urgent needs for disease management.
