Pathogenicity

Crawford (1949) stated that downy mildew caused by Bremia lactucae is the principal and most serious disease of lettuce in New Zealand, causing in some seasons heavy crop losses. Brien, Dye, et al. (1957) stated that it is widespread throughout the country; they also recorded it from two weed species of Lactuca, which, they stated, could act as a source of infection if growing in a market-garden area.
