The natural symptoms in Summer cosmos were consisted of mosaic, yellowing, shoe-string and leaf curling along with severe stunting of the infected plants. The ailments were found to be sap transmissible. &lt;em&gt;Gomphrena globosa&lt;/em&gt; and &lt;em&gt;Chenopodium amaranticolor&lt;/em&gt; were found to be good local lesion hosts producing chlorotic local lesion in the inoculated plants. The virus isolates obtained from the infected &lt;em&gt;G. globosa&lt;/em&gt; plant had wide host range including Amaranthaceae, Chenopodiaceae, Compositae, Cucurbitaceae, Ligominosae and Solanaceae. The dilution end point, thermal inactivation point and longevity in vitro were determined as 10&lt;sup&gt;-6&lt;/sup&gt;, 65°C and 10 days, respectively. The host range test, dilution end point, thermal inactivation point and longevity in vitro suggested that the virus was identical to &lt;em&gt;Cucumber mosaic virus&lt;/em&gt; (CMV). Double Antibody Sandwich Enzyme-Linked Immuno-Sorbent Assay (DAS-ELISA) detected the virus as CMV. The results of the study revealed that the virus disease-like symptoms naturally manifested in summer cosmos plants was identified as CMV.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Key words: &lt;/strong&gt;Summer cosmos, CMV, virus identification.&lt;/p&gt; &lt;p&gt;DOI = 10.3329/jard.v5i1.1463&lt;/p&gt; &lt;p&gt;&lt;em&gt;J Agric Rural Dev &lt;strong&gt;5&lt;/strong&gt;(1&amp;2), 84-93, June 2007&lt;/em&gt;&lt;/p&gt;}, number={1}, journal={Journal of Agriculture &amp; Rural Development}, author={Parvin, MS and Akanda, AM and Rahman, AHMA}, year={2008}, month={Oct.}, pages={84–93} }
