Summary<br />

• In addition to X. fastidiosa strains from blueberry,<br />

strains from lupine, almond, and elderberry were<br />

pathogenic to blueberry.<br />

• Resistance to blueberry leaf scorch in greenhouse<br />

screening agreed with observed field resistance for<br />

most cultivars. <strong>The</strong> development <strong>of</strong> a quick<br />

screening test for resistance to leaf scorch is<br />

possible.<br />

• Differences in virulence or host specificity were<br />

observed in X. fastidiosa strains used in greenhouse<br />

tests.<br />

• Greenhouse tests for the biological control <strong>of</strong> leaf<br />

scorch were positive. Field tests are needed.
