Problems with apple trees

Asked January 16, 2019, 8:38 PM EST

We have a Honey Crisp and Honey Gold Apple Trees. We need help figuring out how so treat the treea so the fruit is good. We treated them for apple magots last year and were still having problems. The outer skin is horrible and the insides are better than 2017. 1 out of 20 apples were actually edible. Hope you can help. Thank you so much.

The apples look more like disease rather than insect problems. Probably fly speck and sooty mold. The attached describes the disease. https://blog-yard-garden-news.extension.umn.edu/2018/10/speckled-and-spotted-but-still-tasty.html
I am also giving you a link describing insect pests. https://extension.umaine.edu/fruit/growing-fruit-trees-in-maine/insect-pests/ The only sure way to keep apples tree from pests is to bag them in zip plastic bags. Here is information: https://extension.umn.edu/yard-and-garden-insects/apple-maggot
