The Worker Protection Standard (WPS) requires you to provide safety measures and training to your agricultural workers and employees. It's time to review and update your WPS training materials at your farm or agribusiness if you haven't done so for several years. You may have posters or manuals that need to be replaced, or you may need to order new training materials. These items are part of the WPS training packets put together by the ISU Pest Management and the Environment Program staff.
