The leaf browning could a variety of thins... chemicals... excessive dryness... insects.. But the growths... Cedar Apple Rust?

i am not much impressed with deciduous trees.. that get ugly leaves by late august ... its natures way ...

then they fall off... and it all starts next season ...

IMHO... there is nothing to be done ...between now and leaf fall ...

you ought to discuss prevention in the fruit forum ... if you really want to grow pretty apples.. like you see in the store.. it usually takes a regimen of 4 to 5 sprayings.. of various things.. starting in dormancy in late winter ... and that is why i gave up on that hobby ...

Thanks everyone for the replies. @ken_adrian that is the thing that had me alarmed this particular apple tree usually does not shed its leaves until around mid-September. So I knew there was something wrong with it. After some consideration I think the brown spots was my doing :/ I tried to spray the tree with some "natural" bug killer since there was an unusual amount of wasps circling it, and I think I might have sprayed a little too much. @i_like_pi it does look like it has Cedar Apple Rust. The neighbors have a crab apple tree in the back, and it looks like that tree has the same growths. So I think that tree might have passed the cedar rust on to mine. I plucked off all of the leaves with the growths and so far I have not seen any more growths pop up. So I think I caught it in time. Once again thanks for the help.
