Gary:

You can prune some now without limiting next yrs crop very much. But there is no way around the fact that either you grow apricots or you grow something else. If you are getting more apricots than you really need, then reduce the size of the tree some. It's hard to recommend how you should do this without seeing the tree. But you can cut off mostly new wood or thin out some big older limbs and allow new ones to grow back over time. Ideally you would do some of both.

At the very least, you do not need to let your tree get any bigger than it already is. Properly done, you can hold the size where it is or even reduce tree size some without missing a crop or reducing production very much.
