Post-harvest rots of avocados in New Zealand and their control.

The postharvest rots of avocados in New Zealand are anthracnose, caused by Colletotrichum spp., and stem-end rots caused by Botryosphaeria spp. and Phomopsis spp. The rots can be controlled by a combination of field sprays and postharvest dips. The incidence of Botryosphaeria spp. was reduced by monthly applications of copper hydroxide, that of Phomopsis spp. by pre-harvest applications of benomyl, and that of Colletotrichum spp. by postharvest dipping in prochloraz. The orchard sprays probably reduced the inoculum present in the tree canopy rather than protecting the fruits directly. The long term problems that may arise from using this schedule, and its possible replacement by alternative treatments, are discussed.
