My Ben Sarek all have their leaves, my Ben Lamonde (right next to BS) have lost all their leaves, my Red Lake (right next to BL) have all their leaves. Both species of my goosberries have their leaves. 

I recall early current defoliation in previous years - crops were not affected. 

I do not see any fruiting bodies on the leaves that do have some black spots. How about pollution with some varieties being more suscebtible?

Beat the apple thieves this year - 80% of my domestic-use crop was picked on the weekend. Loved the one Richelieu I had on my 2nd year P22 whip! Only Spies, Keepsake, Red and Yellow Delicious left - 1-2 weeks to go. One and a half large bushels were picked from an 8' Ida Red on M26 that undergoes heavy pruning in June and late August - tennis ball size and larger apples!
Figs are more than half way (Excel, a large yellow is superbly large and I believe the sweetest!) - now fighting the tree rats for the rest and some later maturing apples. (found that 'Plaster of Paris /Peanut Butter Bob-Bons' were ineffective when I tried tham a couple of years ago.
Waiting for four Siberian pommegranates to mature - moved the potted plant into my greenhouse to avoid the tree rats and raccoons.
Great crop of sweet Damsons. I have also been pruning it heavy to keep the tree dwarfed.

I gave a Turkish Red fig to my 90 yr old mother that did well the 1st year, mediocre last year (as did mine ) and is now dying with the figs shrivelling (over fertilizing?-as my mother is known to do)! I gave a another to my partner that emulated my mother's except that this year it had minimal foliage and No Figs - but it is still alive (also fertilized and possibly excessively watered). Any ideas?

The fact that ribes tend to defoliate early here in southeastern NY has never concerned me.  I question whether it's anthracnose at work although I have no specific knowledge on it- only that I assume that once anthracnose has caused defoliation the vascular system would be kaput and all affected canes would be killed, which they are not.

 

I've always assumed that the issue was only that these are cool weather plants as defoliated canes tend to send out small healthy shoots during cool spells.  Anyone with actual information to clarify my assumptions (or contradict them) would be welcome.
