Over the years I've tried almost everything that those above have suggested.
But where I am in NYState foliage infections are almost entirely fungal so what has worked best for me is Daconil,not the premixed stuff, the concentrate you dilute, and do NOT put anything else in the sprayer other than the Daconil for reasons I've posted about here before.
Info from both Ortho and Bonide who both make the correct Daconil .
And yes,I have a two gallon Solo sprayer which has lasted a long time, just be sure to wash it out each time it's used and flush out the sprayer lines with water.
