Abstract
Phytophthora ramorum, causal agent of sudden oak death (SOD) and ramorum leaf blight, remains a persistent problem of regulatory concern within the horticultural industry. Damages to nurseries have been realized as a result of enforced quarantine and sanitation efforts designed to prevent the spread and establishment of this invasive pathogen. Additionally, the introduction of
P. ramorum to heritage gardens provides a treatment challenge when the goal to prevent local spread conflicts with the preservation of plant collections. There is a need for the development for alternative treatments that may prevent
P. ramorum infection, particularly of foliar tissues from which sporangia are produced.
