Descriptions
Phytophthora citricola Sawada 1927
Phytophthora citricola was recorded from New Zealand by Waterhouse (1957) from cultures sent to the Commonwealth Mycological Institute, Kew, England. Christie (1956) showed that of the hop varieties grown in New Zealand, `Fuggle', `Burford', and `Golding' were resistant to black crown rot. In antirrhinum and petunia P. citricola was associated with seedling root rot. Newhook (1959) showed that P. citricola was associated with death of pines in shelter hedges in the North Auckland area.
