First report of Sclerotinia sclerotiorum on Mimosa pudica in India.

Abstract

Between November 2016 and February 2017, defoliation and stem rot was observed on Mimosa pudica in Medziphema, Nagaland, India. Initial symptoms included paleness of the leaves which gradually drooped, wilted and fell. The fungus attacked the plants from leaves to twigs close to the soil. Occasionally, white mycelia and sclerotia were present on infected tissue of twigs and stems. Approximately 20-50% plants in 3 locations were infected. The causal pathogen was isolated and identified as Sclerotinia sclerotiorum based on morphological, molecular and pathogenicity analyses. The obtained sequences were deposited in GenBank as accession number MF563996 (ITS). This is thought to be the first report of leaf and stem rot caused by S. sclerotiorum on M. pudica in Nagaland, India.
