Pesticides are a cornerstone of agriculture in America. They are also chemicals designed to kill living organisms.

In this series of STPP reports, we use case studies to examine tradeoffs created when decisions are made to use and regulate pesticides.

Risk and Decision reviews the approval of one pesticide, methyl iodide, and determines there were serious shortcomings in the registration process.

Exposure and Interaction assesses the potential interactive effects of three commonly co-applied pesticides. It demonstrates that California Department of Pesticide Regulation (DPR) is required under existing law to assess these potential interactive effects.

STPP's pesticide research is made possible by support from the Clarence E. Heller Charitable Foundation.
