Info

Summary • In addition to X. fastidiosa strains from blueberry, strains from lupine, almond, and elderberry were pathogenic to blueberry. • Resistance to blueberry leaf scorch in greenhouse screening agreed with observed field resistance for most cultivars. The development of a quick screening test for resistance to leaf scorch is possible. • Differences in virulence or host specificity were observed in X. fastidiosa strains used in greenhouse tests. • Greenhouse tests for the biological control of leaf scorch were positive. Field tests are needed.
