Freezing of Blossoms

I live in southwest Nebraska and have a number of 8-10 year old trees that have never bore any fruit. For the past 4-5 years, they have become white with blooms about this time of year. Unfortunately, our last frost date is about May 5. Can I mimic the Florida citrus growers and sprinkle the trees with an oscillating sprinkler? At what low temperature would this be a waste of time? Any other suggestions would be appreciated.
