Check the label before spraying. One of them causes leaf drop on

will warn you). You can also spray the leaves heavily with white oil
to prevent leaf miner.

Yet another possibility is wind damage.

Thanks for the info. The lemon tree does not need water. I have been
spraying with whit oil, but no effect.

Nothing will fix the damaged leaves. It's just a question of figuring
out what caused it to prevent it from happening again. If you have
sprayed with white oil then you shouldn't get any more damage on
previously unaffected leaves, assuming it's leaf miner. But there is
nothing you can do for the other leaves except prune them off, like
Allan said.

No-one has mentioned Pestoil. Is that a no-no now? All the "media gurus"
seem to advise this for citrus leaf miner - if that's what Pat's plant's
problem is... Isn't it early for clm?

I think Pestoil is a variant of white oil and they can be used
interchangably. At TAFE we were told that leaf miner can start in spring
but is usually more of a problem summer/autumn, so yeah, it's early.

Pat, leaf miner makes white, curvy trails in the leaf, as well as
crinkling them. If you're not sure, take a leaf to a nursery and they
should be able to recognise leaf miner.
