Sooty Mold and Citrus Whitefly problem
What are the best natural solutions for a citrus whitefly infestation and sooty mold all over the leaves (due to the citrus fly, I know) on my lemon tree? What is an alternative to using Liquid Gold Copper for the sooty mold, which I can't get a hold of here in Argentina?

I would recommend neem oil. It will take care of both the pests as well as the sooty mold. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
