Last year I had two varieties of peppers, Jalapeno and little, 1-1/2 cmlong
ones from seedlings that the nursery didn't have a name for; several of each
in containers. Both developed leaf miners. Through most of the season, I was
able to control them, more or less, by removing affected leaves; toward the
end of the season (in early December) I just gave up.

What to do about the leaf miners that would a) relieve me of the necessity
of destroying foliage, and b) not, if systemic, leave a poisonous compound
in the fruit?

I don't have to deal with leafminers in peppers, but have occasional problems
with other plants.

Suggestioned controls for leafminers (compatible with 'organic' methods)

-a barrier (light weight fabric) covering the plants -- will interfere with pollination

-repellant -- orange oil

-control by eliminating reservoir of pest in weedy areas, or by planting and
destroying trap crops

-use Neem extracts on plants (will kill larvae before they pupate; don't remove
infested leaves)

The University of California Integrated Pest Management Program has a fact
sheet on leafminers in peppers:
