Sooty Mold on Desert Rose?

yumtomatoes(10a/FLA)September 21, 2012

I have a desert rose that I think became infested with aphids or mealy bugs but it may have been another bug (it was at a relative's house). Whatever it was excreted honeydew (I think) and the now it is covered in sooty mold (I think).

Usually I can get the sooty mold off of plants by first killing the bugs and then using soap and fungicides (daconil) to kill the mold. I haven't tried neem oil yet, but I will try that tomorrow.

The plant is better but still quite a bit of stubborn black stuff on it. I guess it is possible that it is not sooty mold but if so, then what is it and why won't daconil or soap get rid of it?

I have rinsed the plant many times and let it dry in the sun so it is not for lack of rinsing.

I am no expert yumtomatoes, but if you where able to post a photo some of the others here might be able to have a better idea.

Here where I live we can get what is called 'wooly aphids'. They create a wooly white substance and we treat it with a Safer's soap product called End-All II , usually have to repeat 5-7 days later.
Usually wash off an hour afterwards so not to create damage to leaves and it is a contact product, so it has to contact pest to kill it.
This white that I speak of is not just level with surface like that of powder, it is 3 dimensional .

I am wondering if the alcohol treat that Karyn mentioned to me might work on this also.
Check it out before proceeding.

Thanks. The plant was covered in black, nothing white at the time I got her. I had sprayed her with acephate before I brought her home.

I looked up the Safer product; it has insecticidal soap, neem oil and pyrethrins. I have used acephate, soap and next will try neem but I can't use pyrethrins due to my cat.

Where is this alcohol treatment from karyn posted?
