Carnivorous Plants - sarracenia flava fungus


Expert: Sarracenia Northwest - 6/18/2005

Question
Hi,

my flava have recently developed what looks like a white fungus.  It looks like a very fine white soot or baking flour that rubs off easily and appears mottled-fashion across the whole tuber. One one of the plants there's a very small patch of the tuber where the green chlorophyll seems to have been "burned away" like a scald and I can see the grey cellular layer beneath and a red vein.

The plants are growing in full sun and are watered with some rain water every evening.

Do you know what might be causing this and should I cut off the affected tubers?

Answer
Hi Steve,

Definitely cut away affected areas of the rhizome, and any dead leaves.  This sounds like botrytis.  I would also spray the plant and rhizome with a systemic fungicide such as chorothanil.  Check a garden center for fungicides.  Just avoid any that are based on copper, or copper sulfate.  Also I would transplant the plant into fresh media.  That will help get rid of fungal spores.  Lastly, if the plant has any dead sphagnum as a top dressing on the pot, remove it.  It tends to harbor spores.

I would act quickly on this.  Once the fungus invades the rhizome it can kill the plant rather quickly.  It's odd that this is happening on a Sarracenia flava.  We usually have this problem on S. purpurea or S. rubra because of their dense pitchers.

Good  Growing!
