Abstract

<jats:title>Summary</jats:title><jats:p><jats:italic>Melia dubia</jats:italic>, a multipurpose tree species, is gaining importance to meet the demand supply gap of timber, plywood and pulpwood<jats:bold>.</jats:bold> In June 2016, a serious outbreak of wilt disease was observed in <jats:italic>M. dubia</jats:italic> seedlings planted in the Central Nursery of Forest Research Institute (<jats:styled-content style="fixed-case">FRI</jats:styled-content>), Dehradun, India. The disease led to the destruction of one hundred thousand (100,000) seedlings. Earlier in June 2012, serious wilting of <jats:italic>M. dubia</jats:italic> seedlings was observed in Haryana, India. The pathogen was identified as <jats:italic>Fusarium solani</jats:italic> following standard laboratory procedures and sequence analysis of the internal transcribed spacer (<jats:styled-content style="fixed-case">ITS</jats:styled-content>) region of the ribosomal <jats:styled-content style="fixed-case">DNA</jats:styled-content> (<jats:styled-content style="fixed-case">rDNA</jats:styled-content>). The pathogenicity of three isolates has been proved under greenhouse conditions. This is the first report of <jats:italic>F. solani</jats:italic> causing wilt of <jats:italic>M. dubia</jats:italic>.</jats:p>
