I'm amazed you dismiss oils, sulfur and copper as not in line with
organic gardening principles. Traditionally they've been favored by
proponents of organic ag, sustainable ag, Integrated Pest Management,
et.al. Rodale's *Garden Problem Solver* recommends all three noting that
hort oils 'have minimal impact on beneficial insects'. What could be more
organic than dirt dug out of the ground(i.e. sulfur and copper)?
