Having several fruit trees in my yard, I may be able to offer some advice. Your fruit is done for the year. Apples and pears are the last fruits to ripen. For now, water the trees well since they were neglected for so long, they are probably verry stressed. Continue to water every three days for an hour each ( by sprinkler, that is). Next, you need a couple of good books on pruning and care of fruit trees. See if you can take an extension course on pruning from your local college. Some people like to prune in the late fall ( end of October in your area), but I recently took a mini horticulture course that stressed pruning in the very early spring ( late February). At any rate, all major pruning should be done when the trees are in their dormant stage and the sap is not running. That stage happens during winter. Trees begin dormancy when the really cold weather hits and resume running sap when spring begins. Some minor pruning is done in late summer to remove watersprouts and trim off dead or diseased branches. Re spraying; I find it best to contact a yard care company and ask them about their rates and schedules of spraying and what they use. You can ask to have the last schedule of spray ommited, since you want to be able to eat the fruit without risk of poisoning from the sprays. The local garden center can give you a list of sprays and the times they should be applied as well as what they're for, although a good book on care of fruit trees should have that in them. However it may not be germane to your local regulations. I don't like the idea of having to use chemicals at all, but this year my bent towards no poisons and no chemicals has led to bad infestations of aphids, leaf miners, leaf rollres, coddling moth, and those horrible little worms that you find inside cherries, yuck ( shiver)! I lost most of my cherry crop, and all of my crabapple crop. Hope all this helps.
