|The most common cause of brown spots on citrus fruit is the citrus bud mite. You can control these pests with a miticide. I'd remove the affected fruit and destroy it and pick up the fallen oranges as they occur. With any luck you'll still get an edible crop. It's difficult to diagnose a problem without seeing it so you may want to take a sample of the affected fruit to your local cooperative extension office for positive diagnosis. Helpful folks there can suggest control strategies. Orange trees often set more fruit than they can possibly develop to maturity so they drop the excess fruit, sometimes throughout the growing season. It's generally nothing to worry about - it's a natural thinning process.
