Can anyone recommend a homemade, organic and safe alternative to Confidor?

I have a major sooty mould problem which has spread to three somewhat concealed plants during winter.

They are located in a somewhat damp spot which does not have all day sun and are shaded by some older gums (very tall).

I am reluctant to simply cut them out due to privacy concerns and would prefer to try treating them first.

If you are able to suggest a homemade product, could you say how to make it or where I might find the recipe!

I am in western Sydney, Australia.

Thanks so much!

    Sooty mold is a mold that grows on the honeydew of sap sucking insects like aphids, mealybugs, scale, and whiteflies. Control the insects and you control the sooty mold. The honeydew drops from the insects to the leaves and twigs. Wind-blown sooty mold spores that stick to the honeydew then have a suitable medium for growth. When spores germinate, they send out black fungal strands (mycelial threads) that cover the plant tissue and cause the discoloration.

    You can wash the sooty mold off plants with water, but unless the insects are controlled, it will reappear. If they are aphids, a direct spray of water will often times remove them. Insecticdal soaps can also control most soft bodied insects. Liquid dish soaps can work, but some soaps can be phytotoxic to plants. Test any dish soap you use first on a couple of leaves before general use. Here in the US, dish soaps like Palmolive, Ivory, Joy, & Dove have some effectiveness when applied at a 1-2% solution.
