1. How to treat the curved leaf disease for the fruit tree? 2. Last year, my apple tree was infected with some kinds of infects who invade into the apple, and the apple finally could not mature. Please tell us how and when to prevent it? Thanks a lot.

1. The photo is peach leaf curl. Here is what you need to know and what to do: https://extension.umd.edu/hgic/topics/diseases-stone-fruit

2. There are a couple of insect pests of apple that cause fruit drop, or that tunnel into fruit: codling moth and plum curculio. In addition, apple maggot will tunnel through fruit and ruin it.
Here is our page on insect control in fruit. Follow links to the Virginia Tech Spray Schedule and read the descriptions of these pests to determine which aligns most closely with what you see in your apples: https://extension.umd.edu/hgic/topics/fruit-disease-and-insect-pest-control
