Apple IPM Transition Project


Educational activities will occur in several different venues. The concept of the Pest Management Transition Project will be discussed at the annual WSHA meeting, WSU-Extension winter meetings, at grower meetings held by warehouses or fruit packinghouses and in association with other industry meetings. Check the Events Calendar for specific scheduled opportunities.

Implementation Units

The primary in depth educational opportunity for assisting the industry transition insect control programs to use for new insecticide technologies was through Implementation Unit (IU) meetings. The concept of an IU comes from the success of the areawide codling moth management project, which helped the apple industry adopt pheromone technologies in the late 1990s. The positive experience of growers and orchard managers in the areawide codling moth management project resulted from understanding how best to use new technology (pheromones), sharing information on successes and failures of practices, and cooperating on the management of codling moth and leafrollers on an area larger than their own orchard.

An Implementation Unit was comprised of growers and orchard managers who were interested in learning more about new insecticides and how they could best introduce them into their pest control programs and whose orchards are in close proximity though not necessarily contiguous. The number of growers and orchard managers and size of orchards comprising an IU was variable. IU meetings were be held prior to the growing season and at intervals during the growing season and included appropriate crop consultants working with the growers and orchard managers. Education included reviews of how new insecticides fit into an apple pest management program and how programs of individual growers might be designed to take advantages of the new insecticide tools in their program. The advantage of joining an IU was participation in and access to local educational events about new insecticides and focused discussions and planning on how to transition orchard pest control practices to take best advantage of new insecticide technologies.

Members of the IUs were asked to participate in a survey at the end of the project to provide feedback about the usefulness of IUs and the project in general. The survey was also used to gain insight into ways to provide information and education in the future. The results of the survey can be viewed by clicking here or by using the link under "Impact Surveys" found under "Assessment & Documentation" to the left.


The PMTP eNewsletter was produced once or twice a month throughout the spring and summer. Topics included in each issue covered a range of timely information relevant to what was currently happening in WA orchards. Example topics include: Codling moth mating disruption, Woolly apple aphid, Resistance management - just to name a few. Newsletters were initially sent out both by email and regular mail (when email not available) then only by email subscription, as well as being posted here on our web site. Back issues are are stored online and can be viewed anytime via the archive page.


Several educational outreach activities occurred with our stakeholders in the environmental community, sustainable agriculture, government and regulatory agencies and with farm labor groups. Additional outreach in the form of blogs, Facebook and Twitter will continue beyond the termination of this project and will be combined with similar outlets via the Enhanced Western Orchard Biological Control project.


Communication with growers and orchard managers participating in Implementation Units was through a combination of face-to-face meetings, through electronic means (email updates and newsletters), regular mail (when no email is available) and progress reports summarizing project activities, as well as, information made available to the public on this web site.

Communication with stakeholders was available on this web site. Progress towards objectives is provided in various reports in the Assessment and Documentation section of this web site.
