Pest Losses Impact Assessments

The Pest Losses Impact Assessment surveya develop and track “real world” data on the impacts of specific pests and management practices on crop yields, production costs, and profitability. These surveys can provide evidence to support the adoption of IPM strategies, or reveal specific areas in need of improvement or rethinking. 

Critical information for the future of IPM

Regular evaluation of pest pressure, pesticide use, costs, and yield and quality losses due to pests are our most objective tools for assessing IPM status and general progress in agriculture. Oregon State University’s Crop Pest Losses Impact Assessment program (a collaboration between Oregon State University’s Oregon IPM Center, the University of Arizona’s Arizona Pest Management Center, the Western IPM Center, and industry partners) is a process that enables tracking of pest impact status and trends over time, and can focus industry-wide discussions about IPM needs. This information can ultimately be used to develop powerful impact statements for targeted IPM extension programs. These data are also valuable in priority setting and education, and for informing federal decision-making, including the US Environmental Protection Agency’s pesticide registration and review process.
 

A proven track record

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 (Katie Murray, PI), and in collaboration with colleagues at the Arizona Pest Management Center, the Oregon IPM Center 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.

Assessment Surveys

  
 

Crop pest loss assessments are not your normal survey: these are intensive, detailed worksheets designed to capture as much detailed information as possible to get a full understanding of the impacts of pests and pest management strategies on crop loss. Surveys are completed during scheduled workshops attended by crop consultants, university research and extension faculty, and growers that represent participating industries. For example, respondents are asked about acreages, to estimate price per unit of crop, maximum attainable and actual yields, loss estimates caused by specific pests, pest-by-pest information on acres infested, and costs of control. Each survey is intended to inform participants about current pest management successes and needs, and it is also intended to be part of a sequence of annual surveys that can reveal trends and responses to change over time.

Pest Impact Reports

   

Crop Pest Loss Impact Assessment reports contain an abundance of pest management data. For some examples of completed reports, please see the publications by the Arizona Pest Management Center.

This graph, adapted from a report on IPM in Cotton by Peter Ellsworth, shows a reduction in sprays per year for multiple pests. 

 

Oregon Pest impact reports for participating crop systems are currently being produced and are expected to be available in 2020. For more information, contact Katie Murray.
