Abstract
The effects of various host and pathogen factors on disease incidence of Botrytis cinerea (Persoon: Fries) in kiwifruit (Actinidia deliciosa var. deliciosa 'Hayward' (A.Chev.) C. F. Liang et A. R. Ferguson) wer e studied in artificial inoculation trials. High inoculum levels (grea ter than or equal to 25 000 spores/stem scar) and addition of yeast ex tract to spore suspensions significantly increased infection. There wa s no effect of fruit water potential on disease incidence, but total i nfection decreased when fruits were harvested later in the season or e xposed to a curing treatment (6-24 h at 20 degrees C).
