Pesticide Applicators License Recertification Update

We understand that some applicators may need credits for the end of their five-year certification before the end of this calendar year. (40 credit hours by the end of the 5-year certification period. Maximum accumulation per year is 15 hours). Below are links online recertification classes approved by the ODA that will help applicators satisfy this requirement, and step-by-step information on how to register for these courses. For classes offered through the University extensions, please sign up and complete the courses as soon as possible as their staff will be unavailable for help during their winter break.

If you have any questions I will be happy to walk you through the signup process. Thank you for your patience and understanding.

Nichole Linehan, Integrated Pest Management Coordinator

Pests in Portland parks may be noxious weeds, invasive plants, problem insects, plant diseases, rodents or other organisms that cause problems in the landscapes under our care. Our trained and licensed PP&R employees respond to these pests by using the modern principles of integrated pest management (IPM) and invasive plant control.

An Integrated Pest Management program for Portland parks has been in place since the late 1980s. The policies in this program direct every aspect of pest management in our parks, and they serve as rules for all pest management personnel. Updated continuously to respond to new information and new challenges, our program has been hailed as a model of progressive methods and practices by other municipalities and agencies throughout the region. The PP&R program meets or exceeds local, state, and federal requirements.
