SUMMARY Acute infection of Chamaecyparis lawsoniana var. ellwoodii by Phytophthora cinnamomi occurred when many zoospores were present and the roots were growing actively. Active root growth occurred during periods of long day‐length. It is suggested that chronic infection results when few zoospores are present or if infection takes, place when the majority of the root tips are dormant.
