    Arrgg....brown copper patches on new plant

    I received my first Wistuba order about 2 weeks ago and the plants are having problems. The hamata katopasa had stem rot and probably will not make it. I contacted AW and he issued a replacement for this one (next spring). However, now the tenuis and another hamata have these brown copper patches that are getting larger. The patches on the leaves were smaller when it arrived but in the two weeks that I have had them, the patches have been spreading. Does anyone know what I should do?

    And on a separate note, I have these tiny white insects that crawl really fast in the peat which my live sphag grow. There are webs some times. Are these spider mites? I have not been able to catch one since they run like speed demons. There are a few plants in that terrarium so I am afraid they might spread. They run around when I spray my plants, that is how I know they are there. I usually spray isopropanol to fix them if the infection is localized. However, I would rather not kill all my live sphag in the process if there is another means to solve the problem. I have read mixed reviews of using bayer 3 in 1 as an insecticide. Any suggestions?

    Thanks,
    Jen

    Have you experienced any ill effects with neem oil? Seems as if neem oil has mixed reviews. However, I do have a bottle at home that I bought to treat the hamata with. What is the diagnosis?

    Neem shouldn't negatively affect anything. Just don't breathe it in directly.

    The new growth just started to open yesterday. From my brief perusal, it seems to not have any but the leaf has yet to open fully.

    Corky, are you talking about submerging the pots that have the rust spots or the white insect problem?

    Oh, and I do have other fungicides. I just received some Thiomyl that I am going to spray on my seeds. I don't know if I should use this on the plants. I see Rob used this in his study with Edwardsiana on ICPS. I also have a whole collection of fungicides that we use in the lab - generic and some newer generation ones. But I am reluctant to use it on them. I am trying to be conservative here which is not my style.
