Detached Vitis vinifera (Cabernet Sauvignon) berries (12.5 ° Bé) were inoculated either singularly or in combination with spore suspensions of Botrytis cinerea, Colletotrichum acutatum and Greeneria uvicola and the degree of disease expression examined at either 20 or 27 °C. Berries were more susceptible to B. cinerea at 20 °C and to G. uvicola at 27 °C but were highly susceptible to C. acutatum at either temperature. In experiments involving inoculation of berries with mixtures of fungal organisms, B. cinerea infection was diminished at 27 °C by either C. acutatum or G. uvicola but only by C. acutatum at 20 °C. G. uvicola infection was diminished by C. acutatum at both temperatures investigated. B. cinerea reduced the level of infection of both C. acutatum and G. uvicola at 20 °C. The findings have implications for seasonal bunch rot management of grapes in relation to predicted changes in global temperature.
