Not a disease expert, but if it is too late to spray then your only option this year is clean up.

If these are prone to apple scab every year I think you need to ask the question do I want to spray these every year or just be done with them? A chainsaw and a woodchipper will end your frustration very quickly.

i got rid of 11 apples for that reason...

and i am starting to contemplate the crabs ... but their flower show seems to offset the other problems ...

i would cut down a tree long before i would contemplate multiple yearly sprayings of chemicals ...

Search Google for 'apple scab control'. Spraying to control the disease begins with the dormant season but continues through the growing season as well. you can treat now. Good air circulation will help but not eliminate the problem. And one needs to practice very good garden sanitation as well, raking up and destroying any fallen foliage, as the fugal spores can overwinter on the ground or on old leaves.

There are many apple varieties that are resistant to scab and few that are even immune. 'Gravenstein' is my favorite apple but rather disease prone (scab, powdery mildew) -- rather than spraying with a lot of chemicals, I just let it be and it still manages to produce a great crop of apples, even if the tree itself poses some problems. So as I see it your options are 1) spray, 2) ignore but keep as healthy and 'clean' as possible, or 3) remove and replace with a resistant selection.

Dang - I should have mentioned that all of them are ornamentals. Tiny apples. Leaves are always purple. And Ken, for the same reason, I have delayed the begging to get rid of them because the show is specacular. The entire court is nothing but ornamentals that bloom white, pink, and purple for weeks (depending on the weather of course). I don't make the BIG decisions around here - if I had my way they'd come down. Cuz in addition to this mess, I pick up pine cones from Scotch Pines every day - rake, bend, rake. But all of this is really helpful, believe it or not. Thank you -
