Common Tree Diseases
Affecting Your North County, San Diego Trees
Three things are required for a disease to develop:
- A pathogen (the disease-causing agent)
- A plant's susceptibility to that particular pathogen
- An environment suitable for disease development
Plants vary in susceptibility to pathogens. Many disease-prevention programs focus on the use of pathogen-resistant plant varieties. Diseases can be classified into two broad categories:
- Infectious: transmittable diseases caused by microscopic living agents
- Non-infectious: non-transmittable diseases that are inherited or the result of non-living agents
Examples of infectious agents include fungi, protozoa, viruses, and bacteria. Non-infectious diseases, which account for the majority of plant problems in urban areas, can be caused by such factors as compacted soil, nutrient deficiencies, temperature extremes, vandalism, pollutants, and fluctuations in moisture. Non-infectious disorders often produce symptoms similar to those caused by infectious diseases; therefore, it is essential for a Certified Arborist to distinguish between the two to determine proper treatment options.
Only a Certified Arborist should assess a tree for disease, many look similar and treatment should only be done with a professional.
