Kauri dieback is a forest dieback disease of the native kauri trees (Agathis australis) of New Zealand that is suspected to be caused by the oomycete Phytophthora agathidicida.[1] Symptoms can include root rot and associated rot in a collar around the base of the tree, bleeding resin, yellowing and chlorosis of the leaves followed by extensive defoliation, and finally, death.[2][3]
