We had a record number of apple blooms on our Honeycrisp trees this year and were looking forward to great year. However, we noticed that early in the year the leaves were somewhat curled but not really damaged. Then it seemed like we lost most of our early marble sized apples. What apples are left seem to have been attacked by worms? On top of this, we had an aggressive year with additional japanese beetle attack. What is the best course of action for our apple tree?
It seems like our crab apple tree nearby is also very thin.

The first photo shows Honeycrisp apple leaves affected by a physiological condition specific to this variety called Honeycrisp leaf mottle disorder or leaf zonal chlorosis.

The middle photo shows a fruit damaged by weevil-like insects called curculios.
Spring controls are needed to prevent this. Note information and compare your fruit with that shown in the last photo at this website:

The leaf in the photo at right appears to have been damaged by Japanese beetles. The damage seems to be limited so it's probably of little or no consequence.
