Detection of Phytophthora cinnamomi in Soils

Abstract
Detached, six-week old cotyledons of silvertop (Eucalyptus sieberi F.Muell.) floated over samples of eucalypt forest soil were used for baiting P. cinnamomi. The fungus could be identified either directly on the cotyledons or by plating cotyledon pieces on antibiotic agar. The method proved sensitive, reliable and easy to use, especially for broad scale surveys.
