It is not too late, however, I would advise having caution when eating anything from these sprayed trees.
Alternatively, I have a method that I use to control these types of issues that is much less toxic, and as long as you wash the fruit will be completely safe to consume. Use one or more of these ingredients to make the spray, and don't worry if you don't have everything, although it helps. Don't skimp on the ground preparation, though. The recipe is as follows:
First, you will want to prime the ground with dolomitic lime, then spread wettable sulfur to Kill off any infection in the soil. I Also like to spray the plant itself. Mix a few drops of one or more of these ingredients into warm water with a spoonful of coconut oil: Rosemary oil, lavender oil, neem oil, garlic oil, cinnamon extract/oil and for really bad cases, also add clove oil.
