What makes it sound more lie larvae to you? Lately I've been treating it mostly by-hand, am finding a couple more trees each day that have anywhere from 1-4 shoots affected, typically near the tips although any spots where leafs are tight/dense is susceptible....will always approach it in a way as to catch the damn caterpillar (3-10mm, typically long ~5mm), because once their area is disturbed they start trying to move and their locomotion makes them susceptible to just fall onto the substrate surface where they'd just climb back up...I kill them, thoroughly inspect all leaves near them, remove any leaves that were too-affected (unsure how small the larvae can be), and that usually saves the area ie I've got many tips that were affected a week, two weeks, etc ago and are now growing again, still having the scars of the worms but no further injury.I was thinking EXACTLY the same thing
@SU2 Daconil is an anti-fungal. Something else I was wondering about is the "worms" - sounds more like larvae of some type to me...

Then there's the ones that burrow inside the leaf and leave a waxy-filmed trail wherever they go, they're probably 20% of my worm problem, I just clip the leaves mid-petiole (as always) where affected and get those leaves bagged / into the trash away from the garden ;D
