Warning: plague nepenthes fungus

Recommended Posts

For those of you not on facebook, please be aware.

There seems to be evidence that many nepenthes collections are infested with a fungus from the Cryphonectriaceae family which can kill many Nepenthes, it seems to strike hardest when the neps are dormant over winter and apparently lowland neps kept actively growing all year seem to be less at risk.

It is spread easily by spores.

if you are not allready infected, it might be worth avoiding swapping cuttings with other growers and sticking to buying tc plants.

Trying to find out more info, but lumpy leaves, rotted stems and small orange lumps (fruiting bodies).

Corky, theres some discussion in the Highland Nepenthes Group, look for Bill Sherrens recent posts.  Seems its been around for a while and rumour has it some big nurseries are infected.

Thats basically all i know based on what ive recently read on fb.  Until the truth of it is known and more widespread i would caution too much swapping of plants.

Hopefully someone with more knowledge will post here and give us some better information.  To be honest i'm somewhat shocked that it seems to have heen a well kept 'secret' for quite a while.  It's the sort of thing we should all be informed about.

Did you get it recently?
It does that to my plants when I don't take my time to make them aclimatize properly in shadowed positions

It was recently indeed, but the rest of Nepenthes has been correctly acclimated. The thing is that these black dots make me think of fungus more than lack of humidity.

One of mine died like this after I had just bought it, I think it is simply too much light too soon (in combination with possibly lack of proper humidity) , it may recover though, it will just take time (at least a month looking at the picture but could be even three or not recover at all, unfortunately) I wouldn't worry about infestation
