Project Happy Apples

The OSU Extension Service in Central Oregon has a program to assist local residents with control of codling moth. Informative timely emails are sent out to interested residents with advice on when and how to treat fruit trees to reduce or prevent infestation. If you would like to be added to the contact list to get this information, please contact Amy Jo Detweiler. If you have specific questions that are not answered in the updates below, please call your local county Extension office or our office in Deschutes County at 541-548-6088.
