How To Treat My Apple Tree

Question

There are brown/rust coloured spots on the leaves and evidence of some insect infestation through wavy lines. The fruit looks ok. I think it’s a Cox’s.

These articles should help:

The spots could be cedar apple rust which is worse for any nearby junipers.

The wavy lines are leaf miners and they are hard to control once they are inside the leaves.
