“…The leaves were surface-sterilised with 70% ethanol, rinsed with double distilled water and then dried with sterile cheese cloth before inoculation. The leaves were inoculated with 0.5 mL of 105 spores/mL suspension, and incubated under sterile moisturized containers and incubated for 14 days [13].…”

This study was conducted to investigate a characteristic fungal disease, causing leaf anthracnose on B. edulis. A symptom progression from an angular-asymmetrical yellow discoloration to an ulcer-like necrosis caused death to the whole leaf. Colony pigmentations observed among the six isolates ranged from grey to white with slightly raised aerial mycelium to dense cottony mycelium. Most of the isolates showed salmon to bright orange spore-masses that were arranged in concentric rings, and with aging these orange spore-masses evenly distributed towards the culture peripheral. The conidial shapes of all of the isolates were straight and cylindrical with the average conidia length and width, ranged from 55.6-62.8 and 16.8- 24µm. Together with differential tests using fungicide and a temperature regime revealed characteristics corresponding to Colletotrichum gloeosporioides.

“…Notably, C. gloeosporioides, a known pathogen that causes anthracnose in several other plant species also exists asymptomatically as an endophyte in Barringtonia species [12]. Buyoyu P, et al [13] reported the first occurrence of C. gloeosporioides species complex on B. edulis causing anthracnose on the leaves using molecular methods.…”
