Abstract
Isolates of Puccinia helianthi Schw. collected during 1996-1997 were assessed for virulence on a set of Canadian and USA differential lines. All isolates were identified as race 4. In this work, as the sexual phase of the fungus was not found, inoculum introduction was hypothesized. Preliminary observations on field crops suggested that the South African varieties are less susceptible to P. helianthi than the domestic material.
