Project Description

The Crop Pest Losses Impact Assessment (CPLIA) 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 CPLIA program for Pacific Northwest Commodities including potato, onion, cranberry, hazelnut, sweet cherry, grass seed, mint, and pear. This will dovetail with our Integrated Pest Management Strategic Planning (IPMSP) project and takes place on a biennial cycle with participating industries.

Project Aims:

The CPLIA 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

Onion Pest Losses survey workshop: November 9th 2016, Ontario, OR. Local coordination from Stuart Reitz, OSU Extension): Seventeen representatives of the Treasure Valley onion industry (from Oregon and Idaho) participated in the workshop, including 6 research and extension faculty from OSU and UI. Ten participants completed surveys, representing 4,044 acres of onion production across the Treasure Valley. 25 people participated in the pre-IPMSP consultation following the workshop, where pest management challenges and critical needs were identified and documented (very soon we’ll have a link to the onion IPMSP).

Evaluation data: 100% of participants agreed (78%) or strongly agreed (22%) that they gained a better understanding of onion pest and pest management impacts, and 66% responded that they would be likely (44%) or very likely (22%) to participate in a future CPLIA workshop.

Potato Pest Losses survey workshop: December 1st 2016, Hermiston, OR. Local coordination from Sylvia Rondon and Ken Frost, OSU Extension. Seventeen people came to the workshop, including extension faculty from other areas and OSU’s new pollinator expert, Andony Melathopoulos. Eight participants completed the survey, representing 46,785 potato acres across Oregon and Washington.

Evaluation data: 75% of participants reported learning “a little” to “a great deal” about potato pest management, economic impacts of pests, and factors affecting yield losses. 100% reported being likely (75%) or very likely (25%) to participate again in the future.

Cranberry Pest Losses survey workshop, March 1st 2017, Bandon, OR. Local coordination from Cassie Bouska, OSU Extension, and Kim Patten, Washington State University Extension. Ten people came to the workshop, including OSU Extension faculty interested in learning the method. Eight participants completed surveys, representing over 3,000 acres across the Oregon and Washington. The same group participated in the pre-IPMSP consultation following completion of the survey, where pest management challenges and critical needs were identified and documented.

Evaluation data: 86% agreed (72%) or strongly agreed (14%) that they gained a better understanding of cranberry pest and pest management impacts. 86% responded that they would be likely (14%) or very likely (72%) to participate in a future workshop.

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.
