Sudden Oak Death (SOD) is a serious disease affecting oak trees in San Diego, caused by the pathogen Phytophthora ramorum. It spreads in wet conditions, often through California bay laurel trees, and can kill oaks quickly once symptoms appear. Since there is no cure after infection, prevention is critical. The most effective method is phosphonate treatment (Agri-Fos), along with proper tree care, pruning, and removing nearby bay laurels. Early detection and professional arborist services can help protect healthy trees and prevent the disease from spreading.
