This UC Davis study investigates an alternative regulatory approach to lowering pesticide volatile organic compound (VOC) emissions. The study was funded by CDFA's Office of Pesticide Consultation & Analysis.
The following UC Davis report, "Costs of Methyl Iodide Non-Registration: Economic Analysis," was produced under contract to CDFA's Office of Pesticide Consultation & Analysis. CDFA provided a preliminary version of the report to the Department of Pesticide Regulation (DPR) in December 2009, pursuant to the statutorily-mandated Memorandum of Agreement that governs the consultative relationship between the two agencies. The May 2010 final report differs from the preliminary version only by having used an improved method for estimating indirect impacts.
Biocontrol Efforts Against Avocado Pests in California: A Review and Recommendations for Future Proactive Programs for Identifiable Invasion Threats
UC Riverside entomologist, Mark Hoddle, reviews introduced avocado pests and their biological control agents. Hoddle also surveys native avocado regions to document potential new invasive pests and their natural enemies. The project was funded by CDFA's Office of Pesticide Consultation & Analysis.
Under contract to CDFA's Office of Pesticide Consultation & Analysis (OPCA), fifteen UC Cooperative Extension specialists contributed to a study of alternatives to emulsifiable concentrate (EC) pesticides that produce high levels of volatile organic compound (VOC) emissions. It is hoped that the study, which focused on eight key crops, will assist the Department of Pesticide Regulation (DPR) in their effort to satisfy their mandated VOC emission-reduction goals in a manner that minimizes costs to California growers.
The Decline of Public Interest Agricultural Science and the Dubious Future of Crop Biological Control in California
As part of CDFA's ongoing study (funded by the Office of Pesticide Consultation and Analysis) of the future prospects for utilizing biological control methods to manage arthropod pests in California production agriculture, this paper analyzes historical trends in institutional support for biological control research and implementation.
In 2009, the Division used the strategic planning process to enhance program activities and identify future program direction. Representatives from industry as well as local, state, and federal government officials provided input to this process. This process allowed for operational clarity and transparency for all programs. As a result, each of the Division’s branches has begun the process of restructuring at both the branch and program levels.
Two University of California entomologists survey control methods for this key pest, with special emphasis on biological control. This research was partially funded by CDFA's Office of Pesticide Consultation & Analysis.
The California Department of Food and Agriculture’s Plant Health and Pest Prevention Services Division's (PHPPS) mission is legislatively mandated and clearly articulated within the California Food and Agricultural Code, as follows:
Mission — To protect California from the damage caused by the introduction or spread of harmful plant pests.
The California Legislature, enacting this mandate, also recognizes that pest prevention is uniquely positioned to protect California’s urban and natural environments as well as its agriculture. It specifically instructs the Department to protect ornamental and native plantings as well as agricultural crops from the harm caused by exotic pest invasions.
Effects of the January, 2008 CDPR Field Fumigation Regulations: Ventura County Case Study (April, 2009)
Funded by CDFA's Pesticide Consultation office, the following study by the UC Davis Department of Agricultural and Resource Economics examines potential impacts from DPR's fumigant VOC emissions cap in Ventura County.
UC Berkeley entomologist Kent Daane and others review vineyard mealybug pests and their natural enemies, discussing current trends in biological control and potential new research. The project was partially funded by CDFA’s Office of Pesticide Consultation & Analysis.
Funded by the Pesticide Consultation office, this milestone UC Davis report provides the first systematic recalibration in a generation of demand and supply elasticities for the principal California crops. Elasticity measurements are the essential starting point for regulatory impact analysis, since they gauge the responsiveness of consumers and producers to price changes which regulations often impose through unavoidable production cost increases.
Evaluating Scientific Institutional Capacity For Biological Control: A California Study As A Model Regional Network Assessment
Partially funded by CDFA's Pesticide Consultation office, this paper discusses staffing and research emphasis trends in eight institutions engaged in arthropod biological control in California from 1962-2006. The paper was published in the Proceedings of the Third International Symposium on Biological Control of Arthropods, Christchurch, New Zealand, February 8-13, 2009 (pp. 536-543).
This is the final report of a multi-year USDA/ARS study (funded by the Office of Pesticide Consultation and Analysis) examining the feasibility of reducing airborne fumigant emissions through the employment of tarps, water seals, and organic soil amendments.
Socio-Economic Analysis of the North American Commercial Natural Enemy Industry and Implications for Augmentative Biological Control
California growers practicing augmentative biological control rely on the commercial insectary business for natural enemies. Researchers at Santa Clara University and UC Berkeley report on their analysis of this industry as part of the CDFA Office of Pesticide Consultation and Analysis biological control project.

Researchers at UC Berkeley and Santa Clara University have produced a preliminary overview of the current status and future potential of biological control techniques in managing arthropod pests in California agriculture, a topic of rising importance due to persistent regulatory pressure on conventional insecticides. This ongoing study is being funded by CDFA's Pesticide Consultation office.
This directory presents the most recent information and data on the performance and output of agriculture in California. As the statistics and figures demonstrate, California's farmers and ranchers are real visionaries who have succeeded in developing new and better ways to produce food and fiber of the highest quality and with the greatest care for the environment.
The scientists in the Plant Pest Diagnostics Branch perform active research programs. This site features the publications of the current scientific staff, historical publications out of the Branch, databases served from these programs, interactive identification tools, pest sheets, Branch Annual Reports, and the California Plant Pest and Disease Report.
As part of a larger, ongoing CDFA-funded study of the role of biological control in arthropod pest management, University of California experts report on the status of IPM in organic vineyards.
Two UC Berkeley entomologists employ a literature review to assess the feasibility of augmentative biological control as an alternative to conventional, insecticide-based pest control. The project was funded by CDFA's Office of Pesticide Consultation & Analysis.
One of the world's most destructive pests affecting the food supply is the Mediterranean fruit fly, or Medfly (Ceratitis capitata). Given the high societal costs of responding to Medfly infestations in California, significant efforts go towards combating this special threat. CDFA's Medfly Exclusion Program focuses on the Los Angeles Basin because its many ports of entry receive millions of international visitors and products from infested nations. The area is also home to periodic produce smuggling operations.
Economic and Pest Management Evaluation of the Withdrawal of Chlorpyrifos: Six Major California Commodities
In this report, CDFA’s Office of Pesticide Consultation & Analysis and UC research scientists jointly analyze the economic and pest management implications resulting from the loss of chlorpyrifos in six major California crops.
CDFA offers to interested readers this University of California, Berkeley, report analyzing the economic importance of organophosphate (OP) insecticides in California agriculture.
