Sudden Oak Death Syndrome – SF Bay Area Tree Diseases
Posted on 08. Dec, 2008 by admin in Bay Area Tree Care, Oak Tree Care, Pest Control Blog, Tree Spraying Service
In 1995, a new disease of tan oaks, black oaks and coast live oaks appeared in Mill Valley, Marin County, California. Hundreds of trees appeared to be dying suddenly across the landscape, both in woodlands and in suburban properties around the San Francisco Bay Area, but most especially in cities in the Bay Area foothills, such as Palo Alto, Atherton, Menlo Park, Los Altos, Cupertino, Saratoga, Monte Sereno, Los Gatos.
The essentials about Sudden Oak Death:
1. The entire San Francisco Bay Area is at risk for Sudden Oak Death.
2. Black oaks, tan oaks, and coast live oaks are the susceptible trees.
3. Sudden Oak Death is entirely preventable according to the most current research.
What makes Sudden Oak Death sudden? Usually diseases that kill oak trees take ten or fifteen years of progress to kill a large, well established tree. Sudden Oak Death can kill a tree completely within a year. Infections by Phytophthora ramorum (the pathogen which corelates to Sudden Oak Death) on oaks were originally called “Sudden Oak Death” because of the rapid (2 to 4 weeks) browning of leaves without an obvious prolonged period of visible decline.
Sudden Oak Death may be the most serious threat to California Coast Live Oaks, Black Oaks, and Tan Oaks in the history of the state. But, it can be prevented and controlled by chemical methods. We recommend regular bark applications for all of these three kinds of oaks. If the trees are treated with the appropriate chemical, they are very, very unlikely to be affected by Sudden Oak Death. It is possible to control the progress of Sudden Oak Death and perhaps to keep a tree from dying when it has been infected, but prevention is much more effective. If you have any of the above kinds of oak trees, call us to obtain regular spray service. We’ll help you save your trees!
Sudden Oak Death has been found killing oak trees widely in Santa Clara and San Mateo counties as well as in the rest of the San Francisco Bay Area.
This video from UCTelevision explains the discover of Sudden Oak Death and includes an interview with UC horticulturist Pavel Svihra who discovered and named Sudden Oak Death, UC Davis plant pathologist David Rizzo who discovered the pathogen responsible, and Forester Kent Julin of the Marin County Fire Dept. who discusses the fire danger associated with dead and dying trees.
