Project Description

The Pest Losses Impact Assessment survey process was developed by our colleagues at the Arizona Pest Management Center, and is a current signature program of the Western IPM Center. With funding from a USDA Applied Research and Development Program (ARDP) grant (PI Murray), and in collaboration with colleagues at the Arizona Pest Management Center, the IPPC is now building a Pest Losses Impact Assessment program for Pacific Northwest Commodities including potato, onion, cranberry, hazelnut, sweet cherry, grass seed, mint, and pear. This will dovetail with our IPM Strategic Planning project and takes place on a regular cycle with participating industries.

Project Aims:

The Pest Losses Impact Assessment survey aims to develop and track “real world” data on the impacts of specific pests and management practices on crop yields, production costs, and profitability.

Key Activities

Hazelnut Pest Losses workshop: June 2018, Salem, OR. 9 attendees from Oregon, including 2 research and extension faculty from OSU to learn the process. Six participants completed surveys, representing over 17,000 acres of hazelnut production across Oregon. Data analysis continues.

Cherry Pest Losses workshop: March 2018, Hood River, OR. 9 attendees from Oregon and Washington, 7participants completed surveys, representing significant cherry acreage across Oregon and Washington. Data analysis continues.

Cranberry Pest Losses workshop: March 2017, Bandon, OR. Ten participants, including OSU Extension faculty interested in learning the method. Eight participants completed surveys, representing over 3,000 acres across the Oregon and Washington. Data analysis continues.

Potato Pest Losses workshop: December 2016, Hermiston, OR. 17 participants, including extension faculty from other areas. Eight participants completed surveys, representing 46,785 potato acres across Oregon and Washington. Data analysis continues.

Onion Pest Losses workshop: November 2016, Ontario, OR. 17 attendees from Oregon and Idaho, including 6 research and extension faculty from OSU and UI to learn the process. Ten participants completed surveys, representing 4,044 acres of onion production across the Treasure Valley. Data analysis continues.

IPM Impacts

Quantified measurements collected through this process of pests, pesticide use, costs, and crop yield and quality losses due to pests provide objective tools for assessing needs and impacts. These data can ultimately be used to develop powerful impact statements for targeted IPM extension programs. This process also enables tracking of pest impact status and trends over time, and can focus industry-wide discussions about IPM needs, while also providing critical data for comments to USDA/EPA as the need for these arises. Data of this quality and credibility can influence EPA registration decisions, helping growers maintain access to important pest management tools.
