Help all Mr Wizards!
My nectarine twig-end leaves are just shriveling up. No swelling like leaf curl. And this clear gel is near the leaves. Any ideas for me?
And Ms Wizards too! Here's a shot of the gel blob. It's white because I lime sulfured at the first sign of leaf stress.
The first thing that comes to mind is peach twig borer. The larvae eat into the new growing tips and tunnel down a couple inches. This causes the tip to wilt. It occurs on both peach and nectarine. You will find a tunnel and possibly the larvae.
There are other possibilities since I'm not sure what I'm seeing in your picture. Could be brown rot and several other things.
