Is this a good time to spray my fruit trees for insects and diseases?

Last year my peaches had the brown rot fungus. All the peaches were lost to it. What can I do now to prevent that from happening again? We also have two apple trees about 50 feet away.

    Taken from eHow The first spray is the most important: The first spray should be when the leaves are the size of your small fingernail. The second spray should be just before bloomThe 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.

    You do not want to spray while the trees are in full bloom, but you definitely need a spray program to prevent this disease (cleanup is also very important for the control of brown spot). The University of Georgia has a lot to say on this matter here: http://www.ent.uga.edu/pmh/Hm_Home_Orchard.pdf

    You are late! Need to do it when they are dormant. Don't spray with trees in bud or blooming!

    Thanks everyone for your responses. @Mikell Paulson you are right with me being late. The flowers are gone and now the little green peaches are all over the trees. I read on the internet that I can make an organic remedy and spray that at any time. If I see any sign of the disease I'll try spraying.

      @Donna J Copper sulfate is the most commonly used organic pesticide for fruit trees. Just use good sense, don't spray if it's windy and do protect yourself with long sleeves and pants. This is an effective spray, I use it on our pear, apple and cherry trees regularly.
