Services for Common Concerns

Sudden Oak Death is thought to be caused by phytopthora ramorum, a water mold disease.  Agri-fos has been known to prevent this disease.  Once a tree shows the symptoms of Sudden Oak Death, it is not likely to recover although it may have several years before it dies.   If a tree appears not to have symptoms, an annual injection of Agri-fos is strongly recommended as a conservative preventative treatment.  Unfortunately there is no guarantee that an apparently healthy tree is not already infected.  Marin Tree Service is licensed by the California State Department of Agriculture to spray the systemic fungicide, Agri-fos.

Sudden Oak Death

The latest concern in Marin and Sonoma county is the discovery of the Painted Apple Moth, an invader from Australia and New Zealand.  This devastating defoliating pest is attracted to more than just apple trees – it can be hosted by common garden and agricultural plants.  New Zealand eradicated this pest with the use of a biological insecticide based on Bacillus thuringinsis kursraki (Btk).  Although Marin Tree Service is licensed to use this biological agent, homeowners should follow the recommendations of the Department of Agriculture to contain this pest.

Apple Moths

Bark beetles are a major problem in Marin.  There are hundreds of types of bark beetles and some may actually be beneficial.  The most important advice for homeowners is to provide regular care and maintenance for their treasured trees since oaks, pines, and birches are hosts to predators such as bark beetles when they are already slightly compromised.  A variety of EPA approved materials can be used to control these pests - either through topical treatment or root injections.  Marin Tree Service is licensed by the California State Department of Agriculture to apply these treatments.
