    Anyone have a clue? Had a wonderful crop last year but this year I didn't have many blooms and now what I do have are dime size and falling off the tree.

    YES!! Maintaining a regular spray application for insects and fungus:
    November 3, 2012
    Sprayed all the fruit tree’s and grape vines with the copper fungicide as prevention for peach leaf curl next season. 1 oz per gallon used 4 gallon. This is done after the leaves fall and tree’s going dormant.

    February 7, 2013
    Sprayed Bonide All Seasons Horticultural & Dormant Spray Oil (at the recommended 2.5 oz. per gallon) & Fixed copper (1 oz. per Gallon) on all the peach, apple, cherry tree’s & grape vines with good coverage. Used 6 gallon

    February 10
    Fertilized all fruit trees and grape vines with triple 10 ahead of a good rainfall forecasted.

    February 25
    Repeat application from Feb 7, Used 8 gallon really doing a complete coverage.

    April 9.
    Apples only, sprayed captan + Immunox at recommended rate while apple buds were at green tip stage; used 1 gallon.

    May 1
    With some beautiful dime size peaches and ¼ inch diameter cherries sprayed for fungus with Spectracide Immunox @ 1 oz./gal & Captan 50W @ 6.5 Tablespoons per 2 gallon for fungus & for insects with Spectracide Malathion @ 1 oz./gal. & Seven concentrate at a rate of 3 oz per gallon. Mixed all 4 together and sprayed at once, used 4 gallon.

    May 7
    With 2.5 inches of rain in the past week reapplied the May 1 application.

    May 20
    Repeat application with one exception; cutting back on captan to half rate and experimenting with leaves falling off tree’s. 13 Tablespoons/4 Gal. So 3.25/2 is 1.625 /Gal. 1.625 X 3 is 4.875 so used 5 Tablespoons to 3 Gallon. Used 3 Gallon since all that is being sprayed is peach tree’s and cherry tree’s.

    Any help appreciated but think I'm screwed for this season :cry:

    I don't know what the specific problem is, but you shouldn't be surprised that peach tree's act that way in KY. That's too far north for optimal peach growing condition's.

    Hey Kirk! I'm old school crack them open to see if there are worms. Worms do cause fruit drop. Start putting a layer of well decomposed mulch around them each year(3 inches thick)

    Nope, no worms and actually I have cracked them open to rule out frost damage. The hull looks fine so that ruled out frost being the cause.

    Strange my apple trees and other orchards here in TN are dropping fruit. Never seen it this bad. A small Granny Smith in another orchard lost all of its small apples as if they had been frostbit. There was a cool night about two weeks ago when temps dropped to 37...wonder if that might have done it. Let me know if trees have quit dropping.

    Talked to my contacted at Unv of KY yesterday. I sent him pictures of the dropped fruit cut open to see the development of the pit (seed) and it was developing fine, if it was frost it would been dark brown and dried.

    He's at a loss to what it is, said I've done well and kept a spray schedule so wasn't no peaches with sap coming out so wasn't insects either nor disease.

    He didn't mention no reports of others in the area with fruit dropping but now you got me wondering.

    Hate to see the problems Kirk.
    I am getting out my Aluminum helmet on this conundrum.

    Ask a farmer what they have been seeing.
