    I have several coontie palms that have what looks to be scale (little round brown things) and black soot on the fronds. I've used soapy water and a tooth brush to clean it up, but it keeps coming back. I'm not sure what else I can do. Is there something that can rid this for good?

    I usually have this happen on citrus trees at my place in Boca Raton. It appears to be the results of bugs on the upper leaves pooping/tinkling on the tops of the lower leaves and this fairly thick layer of black sooty mold grows in the poop/tinkle/whatever. After the tree has bloomed and the fruit is set I give it a spray of citrus insecticide and the problem goes away with the bugs.

    I realize I'm not speaking at a high level of sophistication but I don't think you want a doctoral thesis, just a way to get rid of the black crud.

    Good luck. Let us know what you do and whether it is successful.

    I have bought the Organocide and will use it this weekend. I've uploaded a picture of one of the plants....maybe it will help. I haven't found anything on the internet like this.

    It looks like some type of scale or even eggs of a moth. I have searched and searched and discovered that the Zamia is the larval food for the echo moth. I can't seem to find pictures of the eggs of this moth. Seen anything like this around?

    Another view of the moth.

    I also found this info on your Zamia. It says that it is prone to Florida red scale.

    Scroll down for Florida red scale.

    This site is supposed to have pics of the eggs of the echo moth, but I can't get the photos to show.

    Since the coonties are in my screened area, I wouldn't miss seeing moths. And that I haven't seen. However the red scale looks like it could be it. I'll clean them up as best I can and then spray.

    Thanks,
    Lynne

    Lynne, you are very welcome. I'd love to know if the Organocide works for you.
