Answer: Bordeaux (lime sulfur) is the most commonly used preventative spray for fruit trees. The first spray should be when the leaves are the size of your small fingernail.
The second spray should be just before bloom.
The third spray should be when at least 90 percent of the blossoms have fallen.
The fourth spray should be 7-10 days later.
Subsequent sprays should be every two weeks throughout the growing season. Stop spraying 2 weeks before harvesting your fruit. Best wishes with your trees.
