donut peach exudate

nelson_ny(NY, 6)June 9, 2013

A couple of years ago I planted out a doughnut peach tree. Unfortunately most of the fruit is affected early on by something that causes a kind of crystallized exudate to form, mostly at the blossom end, which dries hard, almost like pine pitch - see attached photo. My other peach, a white, doesn't have this problem. Any idea of what it is & what can be done about it?

You have some peach scab there (little brown spots). Also the ends of donut peaches are open and they exude gooey sap in rain which hardens to that black stuff. The black stuff on the side looks like injury from bird or bug or something which then oozed and hardened. You can treat the scab but the ooze is just something the flat peaches do sometimes. I had marble-sized balls of ooze on the blossom ends of some of my flat peaches after the recent rain spell.
