    Rash on singalana Tujuh

    Hey guys,

    I've been ignoring this problem for a while now, but since it seems to have spread, I figured I'd try to get some help identifying it. Just like the title says, my singalana Tujuh has developed a strange rash, which began at the stem, and has since spread to the leaves. I'm quite nervous about it, because I have it in my rack, growing quite closely together with some rare and expensive species. Quarantine time?

    Anyway, I haven't been able to find anything quite like it on google, so I thought I'd ask.

    looks like a case of Cercospora fungi.
    Here is a excerpt I stumbled across a while back..
    "Cercospora shows up as reddish or purplish blotches on the leaf blade of
    the plants. It does not generally show up on the pitcher or stem. It may be
    mild and barely noticeable or in some cases so bad that it is fatal if left
    untreated. Some plants are affected more than others. Hairy species like N.
    stenophylla and veitchii seem readily attacked, but so do burbidgea, rajah,
    bellii, and truncata. Fortunately this is easily treatable. There is a
    systemic fungicide, Clearies 3336 Flowable, that will kill the fungus, and it
    has so far proven to be harmless to all CP, orchids, aroids, and even
    sphagnum at recommended doses. It is available through V.J. Grower's Supply,
    Apopka, FL (407) 886-5555. As with any new batch of chemicals try a 2 X or
    4 X test on a plant you can spare like an N. alata. So far I have found no
    problems with the fungicide. One the fungi is eliminated you can often see a
    dramatic jump in the leaf size of the plant, sometimes twice as large as
    before, showing what damage and loss of vigor is caused to the plant. This
    is not a once for all cure however, the fungus can re-infect your plants in
    the future. "

    Also for good measure...look along the leaf midrib and check for signs of scale. I see the tell tale red dot's lined up on the smaller, older leaf underneath the newest, fully formed leaf.

    Good luck with your diagnosis!

    I would have said it was rust fungus...but no matter, treatment for that is exactly the same...I use Captan, but Cleary's is much better if you can get it.
    Some days it just isn't worth chewing thru the restraints.

    I sprayed it with a simple sulfur-based fungicide a while back, but it clearly didn't halt it. Are Cleary's and Captan both systemics? I may run to the store and buy some right now if it'll help.

    Cleary's is a systemic. Rather expensive too.

    Hm.. haven't thought about that, Z. Maybe I should do a little trich watering.

    Got your email and decided to post here since others may be interested as well. Some plants are prone to leafspot/rust pathogens so knowing how to control it is a good thing. I would concur some sort of pathogen, rust or leaf spot. Once it gets into the leaf it does require a system fungicide. Captan or other topical fungicides may stop new infections. Good systemic fungicide that's available at most garden centers, hardware stores..Cleary's is good if you have access to it.
    Ortho max garden disease control. It may kill the sphagnum though.
    Is that a Nepenthes in your pocket or you just happy to see me?
