Abstract
Alternaria, Epicoccum and Ulocladium spp. are potential competitors to Botrytis cinerea. The persistence and survival of these saprophytic fungi on the upper and underside of kiwifruit leaves were investigated in a field trail at Motueka from January to May 1996. Spore numbers and germination were measured as indicators of persistence and survival respectively. Spore number declined significantly on both leaf surfaces with time. Although germination declined significantly over time, after 16 weeks, the germination rate remained > 50% for all three genera. No major differences in spore number and germination between leaf surface nor genus were observed. The effects of UV radiation (254 nm) on spore germination in vitro for nine saprophytic isolates in comparison with 12 B. cinerea isolates are presented.
