Postharvest dipping of kiwifruit in iprodione to control stem-end rot caused by Botrytis cinerea.

ABSTRACT

Kiwifruit cv. Hayward from 4 orchards in New Zealand were tested with iprodione, applied as a preharvest spray or a postharvest dip, to control stem-end rot caused by B. cinerea. Differences in the incidence of stem-end rot existed between orchards but in each orchard only low levels of infection were found. The incidence of stem-end rot was lower in the fungicide dipped fruit than in fruit from the control or preharvest sprayed treatments. The proportion of dicarboximide tolerance in B. cinerea isolates from fruit rots was highest in the fruit that were dipped. There were no consistent differences between orchards in the proportions of dicarboximide tolerance. Iprodione residue levels were higher on the dipped than on the sprayed fruit.
