First report of Ceratocystis fimbriata causing dieback in Conocarpus lancifolius.
During 2017-2018, Conocarpus lancifolius dieback was observed the in Punjab, Khyber Pakhtunkhwa and Sindh provinces of Pakistan. Symptoms observed include sparse foliage, wilting of the leaves and progressive partial to complete dieback of branches, with tree mortality occurring in 1-2 years. The causal pathogen was isolated and identified as Ceratocystis fimbriata based on morphological, molecular and pathogenicity analyses. The obtained sequence was deposited in GenBank (Accession No. MK610728.1). This is thought to be the first report of Ceratocystis fimbriata causing dieback in Conocarpus lancifolius in Pakistan and worldwide.
