Preharvest Detection and Postharvest Incidence of on 'Cripps Pink' Apples in South Africa.

is responsible for significant postharvest losses in 'Cripps Pink' apples in South Africa. The first objective of this study was to determine the presence and incidence of on stored commercial 'Cripps Pink' apple in five major pome fruit growing regions in the Western Cape. As the fungus remains latent until postharvest, the second objective was to develop a rapid molecular detection tool to determine the presence of on asymptomatic 'Cripps Pink' apples from two commercial orchards.
