U.S. Pesticide Policy is Influenced by Stakeholder Comments Managed by the Western IPM Center

Publication (PDF, 2.2MB)

Authors: Alfred J Fournier, Alexa M Brown, Matt, Baur, Danielle Lightle, Katie Murray, Natalie Hein-Ferris, Marion Murray, Steve Elliot, Wayne Dixon, Petter C. Ellsworth

Comments submitted in response to pesticide registration review issues influence federal pesticide policy. An analysis of 95 comments from the Western U.S. submitted in coordination with the Western IPM Center, including 48 comments from University of Arizona, showed that 92% of comments provided substantive data that informed EPA registration review. In 22% of cases, comments had a direct influence on the outcomes, supporting productive and efficient agriculture while protecting human health and the environment.

Insecticide Usage on Conventional and Organic Lettuce in the Desert, 2005-2024

Publication

Authors: John C. Palumbo

The development of accurate data on insecticide usage is important to the assessment of IPM programs in Arizona. A reliable estimate of insecticide use patterns is one of our most objective tools for assessing changes in management practices. This information allows us to build relevant databases for measuring user behaviors and adoption of new IPM technologies. For PCAs, it can translate their efforts into economic terms for their clientele and confirms their value to the lettuce industry by showing the importance of their cost-effective management in desert lettuce production. This summary provides estimates of insecticide use during the 2023-24 growing season and trends on lettuce IPM over the past 20 years.

Trends in Insect Losses and Management on Desert Lettuce: A 19-Year Summary

Publication

Authors: John C. Palumbo

The development of accurate data on lettuce yield losses is important to the assessment of IPM programs in Arizona. Reliable estimates of yield losses caused by key insect pests occurring in lettuce is our most objective tools for assessing change in management practices. This information allows us to build relevant databases for measuring the pest status of important insect species found on desert lettuce, as well as the economic impacts they are responsible for. This information also serves as a resource to assist applied scientists in prioritizing research projects in developing IPM programs for desert lettuce. For PCAs, this data can demonstrate their efforts into economic terms for their growers, and justifies their value to the lettuce industry by showing the importance of insect pests in desert lettuce production. This summary over the past nineteen growing seasons (2004-2023) provides real world data on the pest status of key insect species, economics of insect management, and estimates of yield losses in lettuce.
