Abstract:
<p>Triangle palm [Dypsis decaryi (Jum.) Beentje &amp; Dansf.] is an important ornamental plant in many palm gardens of the<br>world. Recently, a leaf spot disease on triangle palm was observed in Jinnah Garden, Lahore, Pakistan. Alternaria<br>brassicicola (Schwein.) Wiltshire was isolated, purified and identified on the basis of morphological observations, analysing the Internal Transcribe Spacer (ITS) nucleotide sequence and phylogeny. Pathogenecity testing of the causal<br>organism fulfilled the Koch&rsquo;s postulates. To our knowledge, this is the first leaf spot disease report of triangle palm by A. brassicicola from Pakistan that needs attention for its proper control.</p>
