Acute infection of C. lawsoniana var. ellwoodii by P. cinnamomi occurred when many zoospores were present and the roots were growing actively. Active root growth occurred during periods of long day length. Chronic infection probably results when few zoospores are present or if infection takes place when the majority of the root tips are dormant.
