Abstract
Thinning by reducing the number of fruits carried by each spur led to the production of bigger fruit than either removing whole clusters from all over the tree or removing all the fruitlets from part of the tree. Ethephon applied at the balloon stage of flowering reduced the number of fruits and increased fruit size. Carbaryl was the most effective fruitlet thinner, applied when the average fruitlet diameter was between 9 and 13 mm.
