A Technical Report from The Bartlett Tree Research Laboratories

Phytophthora root rot is a widespread disease of landscape plants. The name Phytophthora is a Greek work literally meaning “plant destroyer”. These pathogens grow in the cambium and sapwood causing death of the tissue. Loss of water and nutrient absorbing capacity and stored carbohydrate reserves in the root cause a gradual, or sometimes-rapid decline of the above ground portion of a tree.
