White rust symptoms appeared 4days earlier and were significantly more severe when a variety of B. juncea resistant to downy mildew but highly susceptible to white rust was first inoculated with A. candida followed 10days later with H. parasitica. DNA extractions of tissues indicated H. parasitica had colonized the asymptomatic plants systemically. These are the first reports of (a) the systemic colonization by H. parasitica in a host resistant to downy mildew, and (b) the increase in susceptibility of a Brassica to white rust disease from asymptomatic colonization by H. parasitica.
