Tobacco streak virus (TSV) causes necrosis on leaf, veins, petiole and stem in Blackgram. The sap extracted from the infected blackgram plants remains infectious upto 24 hrs at room temperature. Infectivity of TSV on cowpea progressively reduced in response to increasing in the temperature and dilution. The present investigation was carried out to test the physical properties of TSV such as longevity storage period, thermal inactivation point and dilution end point on Cowpea (CV C- 125) isolated from naturally infected Blackgram plants (CO-8).

Keywords: Tobacco streak virus, Blackgram, Necrosis, Dilution end point, Longivity, Thermal inactivation point
