Answer: Bordeaux (lime sulfur) should be applied as soon as the buds break, and reapplied until the leaves are fully expanded. Spray at prepink, pink, and after the petals have fallen. More detailed information will be included in the directions of the fungicide you purchase. If the problem with your apples is not a disease, but with insects, there is also a spray schedule for coddling moths and apple maggots. Timing is really important when dealing with these pests. Your cooperative extension office has publications to help guide you through the process. The address for the Ashland office is: 804 Us Highway 250, Ashland - (419) 281-8242. Best wishes with your apple trees.
