Septoria is pretty bad in the area, seems like every blade of grass has rusty spots and every weed too, whatever they are.

Neem oil might run your ladybugs off or even kill some of them. I wouldn't do anything that would run off my ladybugs because they really do a job on aphids which spread diseases. I don't think Neem oil will do much to stop Septoria either. Copper sprays seem to work better on Septoria for me and if it is already a problem then I use the bleach spray followed by copper. Neither of these sprays seems to bother ladybugs.
