100% Apples and Pears CODDLING MOTH #277262

Asked September 10, 2015, 5:27 PM EDT

I live in lower mainland of BC. After my husband died, I engaged the local tree farmer to spray my domestic orchard of about 15 apples tress of various varieties, and several pear trees. This year he didn't spray for reasons of his own, and did not tell me. ALL of my fruit was infected with either coddling moth or apple maggot. I have picked up all the windfall and stripped what was left on the trees, and destroyed them. The trees are still in leaf, and I wonder what I can spray the trees with now, as we seem to have a third generation on the go. I will prune and spray in the spring, as aggressively as I can, since I've not done it before. Please help if you can.

Sounds like you are doing a lot of right things by removing the dropped fruit etc. Coddling moths are not an easy beast to deal with once the populations get a bit out of control, but a combination of strategies, some chemical and some not should put things right. Here is a good factsheet which describes various approaches in useful detail:

And in case there are  jurisdictional differences in what might or might be allowed in BC, here is another source put out by the BC government.
Good luck

Dear Glen N., Thank you for the information. This is the first I've read about Codling Moth infecting English walnuts. I have a large tree next to my orchar, and wondered what was infecting the nuts. More despair. I have some specific questions: 1. should I remove and burn all of the bark mulch around the base of all of the trees? 2. What can I spray the trees with now, before they enter dormancy. I have stripped all of the fruit from all of the trees, save the walnut which is very large. I will just have to get rid of the nuts when they fall. My husband put his heart and soul into the orchard, and I'd like to try and save it in his honour.. I would make him very sad to know that I have to cut and burn all of our hazelnut trees, affected by Eastern Filbert Blight. Any other suggestions you have will be greatly appreciated. Sincerely, Terry Komusi retired physician who knows nothing about plant diseases.

It sounds like you have some complex issues going on there, which really need someone who can see the context in order to give you the best advice. Online advice is good when it's something fairly straightforward, but has limits for more complex problems that involve different plants and possible pathogens. I suggest you contact the local offices of the BC Ministry of Agriculture in order to have local extension officer come out and take a look at your orchards. Here is a list of few particular contacts what may be able to put you on the right track, depending on your particular location (http://www.agf.gov.bc.ca/cropprot/contacts.htm) These are precious trees and you should get only the best advice onsite. Best of luck.
