Apple Tree Pests
I forgot to spray a fungicide on my two apple trees. They have both already put out tiny apples. Is it too late to spray to avoid the worm infestation I had last year (when I also forgot to spray in Spring)?

Hi, it sounds like you forgot an insecticide as opposed to a fungicide. The worms you mention are most likely codling moth. They have already started laying eggs and attacking fruit. You could try to protect fruit that have not yet been attacked with fruit sox: https://www.homeorchardsociety.org/fruit-sox/. If you have not done any fruit thinning you could probably pick the attacked fruits after late June and set your sites on spraying in time for the second codling moth generation, currently forecast to occur around the first week of August.
