New pests and diseases: Sudden oak death syndrome fells 3 oak species
California Agriculture 55(1):9-19. DOI: 10.3733/ca.v055n01p9.
A new Phytophthora species appears to be resonsible for the death of large numbers of oak trees, a phenomenon currently called “sudden oak death.”
The authors are also indebted to the many volunteers and students who made much of this research possible. The field experiment, the in vitro fungicide tests, and some of the inoculation trials would not have been possible without the help of Mr. Ralph Zingaro. They are also grateful to Susan Frankel and the U.S. Forest Service for funding provided through a cooperative agreement between UC and the Pacific Southwestern region of the Forest Service.
