Abstract

Experimental data on the host, range and physical properties are recorded of cassia mosaic, a previously undescribed virus disease of Cassia occidentalis L. in New Guinea.The virus is readily transmissible to Cassia occidentalis, C. tora L. and Crotalaria anagyroides H.B. et K. The dilution end point lies between 1:1,000 and 1:2,000, thermal inactivation point between 60 and 62 degrees C. for an exposure of ten minutes and longevity in vitro less than 168 hours.
