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

Bill is probably right about the Lady Beetles and Neem Oil, but it's probably not going to harm them unless you hit them directly with the spray. If you don't have any aphids on your tomato plants you are not likely to find many Lady Beetles hanging around anyway.
I agree also that Neem Oil alone is not going to impact Septoria much.

To use potassium bicarbonate, is there a brand made for gardens? If not, how do you use it?

It might be OK to mix Excel LG with those things, I don't know, but why? Phosphourous Acid is not something you should be applying regularly since it's systemic in the plant. I also know applying too much of it will cause leaf burn. I know because I did it!
Greencure is the commercial potassium bicarbonate fungicide product for gardeners. Or you can just buy potassium bicarbonate and make your own formula.
