What has happened to apple leaves .i sprayed mancozeb +urea+boric acid +zinc after 2 days of hail storm so to recover hail damage . . Leaves are looking as burned spots . .plz suggest .

Suggestion… read warning labels on chemicals that you are spraying. I think you overloaded the trees and those are definitely burns. Time will tell what damage you caused, hopefully nothing that cant be repaired.

Any particular reason you are spraying that much on to them at 1 time?
