Abstract
Copper sprays were applied at monthly intervals in a staggered-type sprays experiment in order to determine the optimum period for control of pre-and post-harvest diseases in Fuerte and Hass avocado cultivare. The critical periods for black spot on Fuerte appear to be later at Everdon Estate, KwaZulu-Natal than generally accepted for the rest of the industry. Anthracnose, Dothiorella / Colletotrichum fruit rot complex and stem-end rot were readily controlled with copper sprays on both cultivars. Copper sprays applied from November onwards should therefore be efficient for the control of post-harvest diseases. Neither production of Hass and Fuerte, nor fruit size distribution of Hass were significantly influenced by any amount of copper sprays.
