Pesticide Exposure and Hazard Quotients: Understanding where pesticide hazard comes from in the landscape 

Understanding where pesticide exposure happens in the landscape is critical to implementing the best management practices that will protect bees from unintended pesticide contact. But how do we even measure pesticide risk? What models are scientists using to understand how bees are exposed to pesticides and how does that impact real world management practices? In this talk, we will explore the finer points of pesticide exposure, hazard, and risk. Finally, we will discuss how research at Oregon State focuses on understanding the pesticide exposure associated with on and off crop forage. In 2020 and 2021, we collected over 300 pollen samples to understand how pesticide hazard changes to bees throughout a pollination circuit in sweet cherry, meadowfoam, clover, and carrot seed. This presentation will examine what pesticides are found in these environments and alternative forage within these systems.
