Can I second this. I know that some fungi may be immune to it, but
Benlate is really quite affective if used at full strength and liberally
sprayed onto the leaves. It is also systemic, so spray it all over the
leaves, not just the part affected. This could also influence the
effectiveness of the fungicide.

Secondly, about S.purpurea colour, I have a Sarracenia purpurea subspecies
venosa which goes bright red in full sun. I believe that the colour is
influenced chiefly by the amount of SUNLIGHT (I'm not so sure about artificial
light), although obviously the individual genetics of your plant also effects
the colour, also different forms (I.e Sarracenia purpurea sst. purpurea f.
heterophylla).

Right, I'll get off my soap box and crawl under my stone,

Bye for now
