Abstract
Two major post-harvest diseases have been found in New Zealand avocados (Persea americana Miller): anthracnose, associated with Colletotrichum species, and stem-end rots, associated with Botryosphaeria and Phomopsis species. Several Fusarium species have been also isolated from fruit rots. Scab (Sphaceloma perseae Jenkins) is recorded for the first time on New Zealand avocados.
