Postharvest rots of hand-harvested blueberries increased when infected spore-bearing fruits were introduced into simulated hopper-fed pint (551 ml) filling lines. Infection of Bluechip blueberries (Vaccinium corymbosum) handled on surfaces contaminated with conidia of Colletotrichum ranged from 3.6 (for dry-handled fruits) to 63.5% (when fruits were handled wet). Similar results were obtained with Alternaria tenuissima. Added moisture, added inoculum and stem scar size/wetness all contributed to increased rots. Ripe rot of Blue Ridge southern highbush blueberries (V. corymbosum) caused by Colletotrichum increased from 2.3 (in clean buckets) to 26.2% (in infected buckets). Ripe rot significantly increased in Tifblue rabbiteye (V. ashei) fruits when wet fruits were packed in infected picking containers. The introduction of a single spore-bearing fruit/half-pint (170 g) container significantly increased ripe rot in wet-handled Tifblue rabbiteye fruits.
