While there is no cure for Sudden Oak Death or other P. ramorum-associated diseases, there are preventive measures that may protect plants.

The publication “Protecting Trees from Sudden Oak Death Before Infection” provides helpful treatment information for areas not currently infested but at risk.

Guidance for application and use of phosphonate chemical treatments (such as Agri-fos® ) is available at the UC Berkeley Forest Pathology and Mycology laboratory. Be sure to see the 2016 updated treatments for sudden oak death.

More information about removing bay trees that are growing near susceptible oaks is available at the Phytosphere Research website.
