Q.Peach tree
My peaches are starting to exude a clear gunk that hardens and looks like a lump of amber. What could this be. Also 3 or 4 have already fallen off the tree. My tree is probably 30 years old. I hate to lose it! By the way, when I uploaded my pics, it shows several others. Sorry!

This could be Borers, Stink Bugs or Fruit Moths.
You will need to investigate further to help determine the pest involved.
