My clump birch tree (approx. 8 years old) is dropping a large amount of leaves. I fertilized it last fall & used a pesticide (12 mo systemic type) on it this spring. It is planted in full sun & receives water from sprinkler system 3 times per week. It has done this previous summers but this year it appears to be dropping more leaves than usual. Is there something I should/can do to prevent this?

Birch trees tend to drop some leaves throughout the season normally, and some years this is more pronounced that others. Plus, they are also known to begin fall leaf drop early.
There is nothing you can do to prevent this. It's possible that all the irrigation may be encouraging excess leaf production in spring, which in turn they shed because they don't need that many leaves.
