Abstract: Postharvest fruit rot diseases of avocado caused by Colletotrichum gloeosporioides and Diplodia natalensis were reduced significantly by treatment with an antioxidant, butylated hydroxy anisole (BHA) (commercial name, Xedaphen-20). Experiments were carried out in the USA on cv. 'Hass' and in Israel on cv. 'Fuerte'. There was a significant reduction of decay by a single treatment of Xedaphen-20 at 1200 µg a.i./ml; the mixture of the antioxidant with up to 250 µg a.i./ml prochloraz further reduced decay development. It is suggested that the antioxidant might reduce decay development in avocado by modulating the natural fruit resistance. The results obtained in semicommercial trials in the last three harvesting seasons were discussed.
