                    Assessing Exposure and Risk to Pollinators and Plants: The 2017 Fall EMPM will provide a forum for presentations on methods for assessing pesticide exposure and risk to pollinators and plants. Potential pollinator topics include novel risk assessment approaches and advances in model development. In regard to terrestrial and wetland plants, potential topics include the status of the EPA's new exposure model and investigations of variability inherent in seedling emergence and vegetative vigor toxicity studies. Updates on ongoing topics will also be provided,                     *e.g.,*                     synergy, fumigant guidance, seed exposure modeling for terrestrial vertebrates, the Spatial Aquatic Model (SAM), and methods for interpreting pesticide surface water monitoring data.
