But Sundays River Citrus Company (SRCC) managing director Hannes de Waal said updated figures showed 50% of the orange variant had gone to waste.
“Navels are especially popular for export because they are available at a time when other oranges are not in season,” De Waal said.
“But now, thanks to this natural phenomenon, we will lose half the harvest at a cost of between R400-million and R600-million to the local farmers.”
This amount, though, is only from the loss in actual fruit.
De Waal estimates the amount could run close to R1-billion if the entire supply chain is taken into account.
Valencias, another orange variant grown for a different time of year, were also affected, but to a much lesser extent than the navels.
