I don't get down to my allotment as often as I would like and recently have been dealing with other problems like lifting and replanting Plum trees in raised beds (it's by a pond and too moist for them so it's do or die). Today I noticed Codling Moth holes in my Cooking Apples. I've destroyed the infected apples, picked those that were a decent size (a few weeks too early I know) and left those that aren't big enough. I know I should have set up traps in Spring and sprayed in June if need be but didn't. Is there any point in spraying this late? I'm wondering if the exceptionally dry summer here (Kent) might mean conventional wisdom goes out the window?
