Abstract:

Occurrence of anthracnose disease of Pleomele (Dracaena reflexa Lam.) is first time observed during mid-August to October, 2017, from nursery garden of Salt lake City, Kolkata, West Bengal, India. Typical small to medium sized light grey - white spots surrounded by irregular dark brown zonate margin with numerous production of concentric brown to black dot like stromatic structures are observed on the upper surface of leaves. Based on cultural, morphological, vegetative and reproductive structures, the causal pathogen of anthracnose disease is identified as Colletotrichum gloeosporioides which is being considered as new record from West Bengal. Spores of Colletotrichum gloeosporioides produced on potato dextrose agar, are hyaline, 1-celled, smooth walled, eguttulate, cylindrical with rounded ends measuring 8.2 – 16.8 (av. 12.6) x 3.0 – 5.5 (av. 4.4) μ. The hyphae produced are hyaline, thin and septate, varied from 10.5 – 14.2 (av. 13.2) μ in diameter. Acervuli are pale brown to black, 133.5 – 195.1 (av.167.2) μ in size with numerous, black to dark brown, 1 – 3 septate, unbranched, 10.1 – 13.3 (av. 12.0) x 3.0 – 3.8 (av. 3.4) μ sized pointed setae.


Keywords: Pleomele, Dracaena reflexa, Anthracnose, Colletotrichum gloeosporioides, West Bengal.
