Abstract
Oak wilt, caused by Bretziella fagacearum, is one of the most destructive diseases affecting urban and rural oak trees in the Midwest USA. The disease is difficult to control due to the systemic movement of the pathogen through the vascular system of oak trees. Primary approaches used to control oak wilt include disrupting underground spread through root cutting and the prevention of wounding during the high-risk period that the insect vectors of the oak wilt fungus are active. Preventative or therapeutic treatment of oaks using systemic injection techniques are a more recently developed control approach used by arborists and urban foresters. Systemic injection into xylem vascular elements of woody plants, however, involves physical wounding to the lower stem or root crown. The ability of a tree to compartmentalize such damage may affect tree vigor or even a tree’s ability to survive after repeated treatments. This thesis summarizes results of research on compartmentalization of damage associated with systemic injection of propiconazole fungicides in northern pin oak in Anoka County, Minnesota.
