Mechanisms accounting for natural resistance of unripe mangoes and avocados to fungal pathogens is discussed under the headings: activity of preformed antifungal compounds; preformed antifungal compounds in mango fruits; resistance of avocado fruits to Colletotrichum gloeosporioides [Glomerella cingulata]; induction of avocado preformed antifungal compounds; concentration of the compounds and decay resistance; modulation of diene levels and practical disease control; and potential toxicity of natural compounds in food products. Antioxidant and high carbon dioxide treatments inhibit decreases of the avocado antifungal diene compound during ripening or induce the accumulation of higher levels. It is concluded that the diene is a physiologically important agent affecting resistance to G. cingulata and that treatments with antioxidants that affect levels of preformed antifungal compounds may be useful for practical disease control.
