Black tar-like exudate on peach tree branch ends

Asked April 21, 2013, 8:47 PM EDT

My peach tree has this strange black disease on the terminal branches.
It doesn't fit the description of "black scab". I don't know what it is or what to do about it.
Can you help?

If the shoot tips are swollen, I think it is an insect and not a disease. Oriental fruit moth is a pest of peaches that attacks the growing shoot tips early in the spring and then the fruit later in the season. If there is no fruit they will continue to lay their eggs on the shoot tips. There are 3 generations a year. Here is a link to more information.

I also attach a photo I have of the tip damage but I have seen the tip much more swollen than in this photo
