So, I sprayed the leaves down with a pesticide soap last weekend. I don't think that it worked, since all of the leaves still have their spider friends hanging around. I might try some Ortho Home pest spray that I have left over. The one leaf's brown spot seems to be growing. Now, a Third leaf has a quarter-sized brown spot developing. These spots all have yellow borders around the dried brown leaf material. I can see other small black marks along the leaf as well. This is what I thought that bug damage was. The black spots are tiny, and erratic in shape, so It doesn't look like the native fungal damage to my area, or either of the Sigatokas. They look like little scratches that have scarred over.
