Practical Solutions for Pesticide Safety

Handheld pesticide application takes place in farming and forestry work, and unintentional exposures can be common. Few evidence-based and practical solutions have been developed and shared across these industries.

Project Overview

PNASH works with farmers, educators, and researchers across the Northwest to test and develop solutions originally developed by growers and workers for themselves. We have expanded from our original airblast application systems, to now include handheld and greenhouse applications. Each solution is assessed for the goals:

  1. reduce exposure,
  2. are practical, compatible, and convenient,
  3. support the requirements and training for state regulations and the revised US EPA Worker Protection Standard.

Findings to Date

  • 50% interviewees have story of adoption/use in field.
  • Reviewers found the online solutions visually appealing and accurate and the curated solutions useful.


  • 21 new solutions have been published in English and Spanish on our webpage. Each solution describes how pesticide exposure is reduced and share practices to reduce the exposure including a supply list, tips, photos, setup and use instructions, and links for more WPS information and relevant regulations.
  • Developed a new remote approach to engage partners by providing a custom tablet used to gather pictures and conduct live walk-throughs and interviews.
  • Completed adoption scenarios. For example, a participant adopted the room access protocol solution, motivated by the use of less pesticide products because they would only need to treat one room instead of several rooms.
  • Developed a new PNASH e-learning course, Pesticide Learning Solutions, to demonstrate how to read a pesticide label, discuss pesticide exposure pathways and how to reduce exposure, share best practices for pesticide application, and provide pesticide safety resources from PNASH and regional and national sources.

Next Steps

In the coming year, we will be presenting solutions, developing flashcards for use in training, and evaluating grower interest and use. Our promotion plan includes social media and meetings (remote and in-person). We are partnering with Oregon State University Pesticide Safety Education Program (PSEP) and the national Pesticide Educational Resources Collaborative (PERC). In addition, we will also be participating in agricultural health and safety events in Washington and Oregon to share solutions and resources.
