摘要
Leaf spot disease of Aloe vera (Aloe barbadensis Mill.) was prevalent year-round, peaking in February, with symptoms of reddish-brown to dark-brown sunken spots on leaves. The pathogen, isolated in February 2022–2023 in Kalyani, West Bengal, was identified as Colletotrichum siamense through morphological and phylogenetic characterisation. This is the first report of C. siamense causing leaf spot on Aloe vera in India.
