A Gardeners Forum Forums General Discussion Plant pests and problems Dying curry tree

One of my small curry trees (Murraya koenigii) is dying =( At the top of its trunk is what looks like very thin cobwebs, along with some small brown bumps and other brown bits caught in the webbing. Many of the leaves are dropping off.

Here's a photo of the problem:

What can I do to help my poor little plant?

Again, scales and probably spider mites.
