Citrus growers in the Murray Valley have been advised to leave the smaller fruits on the trees this year to ensure that they maximise their returns.
Larger fruits are demanded by most export markets and, as the currency is still so high, it could be unprofitable to pick the fruits that are not in demand overseas.
Mary Cannard, from the Murray Valley Citrus Board, says it will still be a difficult year for growers, despite an average large fruit size.
"You've nurtured your crop all season long and to leave it hanging on the tree just to watch it drop on the ground would be a very difficult thing for growers," she said.
"For your profitability, you really need to make that decision."
