Olive
A disease caused by the bacteria Pseudomonas syringae and is characterized by the formation of rough woody-like galls on branches and trunks that are approximately 1 inch thick. Defoliation and reduced yield in mature trees occurs, and young infect trees might die. The bacteria penetrates through cracks and openings in the plant’s tissues provided by freezing injuries (or pruning) and is easily spread by water splashes. The infections will likely occur during wintertime, while the development of knots will take place later on such as spring or summer. All varieties are susceptible.
