The California Department of Food and Agricultur<\/a>e\u2019s (CDFA\u2019s) Office of Pesticide Consultation and Analysis<\/a> (OPCA) was formed in 1992 following the formation of CalEPA\u2019s Department of Pesticide Regulation<\/a> (DPR). Prior to this time CDFA was responsible for pesticide regulation in the state. OPCA’s primary role is to provide DPR with impact analyses of proposed pesticide regulations, specifically actions detailed in Food and Agriculture Code (FAC) Section 11454.2. The consultative arrangement was established primarily to ensure that the economic impacts on California’s agricultural industry would be evaluated before the adoption of new pesticide regulations. OPCA is funded through the pesticide mill assessment collected by DPR for CDFA. <\/p>\n\n\n\n

Currently, OPCA consists of five scientists with backgrounds mainly in agricultural entomology. We work closely with UC Cooperative Extension scientists and agricultural economists while doing analyses. Despite our office being in the back of the building, we welcome stakeholder communication; we will happily talk your ear off about analytical methods, data, and regulatory frameworks.    <\/p>\n\n\n\n

Our analyses are specifically focused on assessing the immediate impact of the proposed regulation on pest management costs and effectiveness. We use pesticide use reporting data to estimate future use based on historical trends and to predict how the loss of specific active ingredients might affect those use trends. This methodology was developed by Dr. Rachael Goodhue, the chair of Agricultural Resource Economics at UC Davis, OPCA, and a host of other collaborators and published in 2017 (https:\/\/pubs.acs.org\/doi\/10.1021\/bk-2018-1283.ch020<\/a>).   <\/p>\n\n\n\n

In the past five years, OPCA has completed reports related to the withdrawal of chlorpyrifos, multiple iterations of the neonicotinoid mitigation regulations, and multiple iterations for both sets of 1,3-Dichloropropene (non-occupational bystander and occupational bystander) safety regulations. Public reports, publications, and white papers are available on our website https:\/\/www.cdfa.ca.gov\/oars\/opca\/publications.html<\/a>.   <\/p>\n\n\n\n

Since 2019, OPCA has also started running several grant programs including Biologically Integrated Farming Systems<\/a>, Proactive Integrated Pest Management<\/a>, and support for IR-4<\/a>.  <\/p>\n\n\n\n

In a world of rapidly changing pest threats, we are adapting too! Our \u201cProactive IPM Solutions<\/strong>\u201d program is now \u201cAdaptive IPM for Invasive Agricultural Pests\u201d<\/strong>, moving beyond “proactive” to a more responsive, dynamic, and inclusive approach. Our program focuses on developing and implementing adaptable IPM strategies that enable swift action against emerging invasive pests in California, whether they are newly introduced, resurging, or expanding their range. We are dedicated to refining existing methods and exploring new solutions, especially where pesticide resistance poses a challenge.  <\/p>\n","protected":false},"excerpt":{"rendered":"
