Q.jelly like substance on peaches
the first crop of peaches on my tree have globs of a clear jelly like substance clinging to the fruit. Some of the first peaches on my 2 year old peach tree had shriveled and dropped before fully developing. I understand the tree can drop this fruit as a ‘natural thinner.’ Now I am seeing a crystal clear gelatinous substance all over the fruit. What is causing this and how can I treat it?

That is caused by peach borer. This article will help you with that:
