White powder on apple seedlings...
 

My mother's friend's son has grown some apple seedlings from pips. They are
indoors, about 4 inches high. However the leaves have become covered with
some kind of white powder, looks like a light dusting of flour. I assume
this is some kind of bug. What is it, and how do I treat it?

Try looking with a strong magnifying glass. I think you'll find that
there are tiny aphid-like insects there.

Wash the blighters off with slightly soapy water and as soon as it
reappears, repeat the treatment. You can use a systemic insecticide as
you won't be expecting apples for a year or - ten.
