Friday Mar 01, 2024

The following links will take you to some of the best online resources for potato pest and disease management.


Potato Decision Aid System: Welcome to our new website. It features spatial models of insect pests using data from potato pest monitoring networks in the Pacific Northwest. It also includes developmental models for important insects. Potato DAS was launched in 2021 to provide time-sensitive information to assist with potato crop management. There is no subscription fee and you can register for an account here, to use the system.

NW Potato Research Consortium: This website presents a great overview of potato pests (insects, nematodes, and more) and diseases. There are insect pest trapping guides and potato pest management guides available for download. There is also information about beneficial organisms that help to control pests.

The IPM Guidelines for Insects and Mites in Idaho, Oregon and Washington Potatoes: This guide has detailed pest management information. It is a good resource if you need help selecting and applying insecticides for their best effect. The last update was in 2019, so be sure to check that the products mentioned are available for use.

Pacific Northwest Pest Management Handbook Series: The handbooks are tools to help commercial growers make decisions regarding control and management of important insect pests, diseases, and weeds that affect crops in the region. They are updated every year. See below for links to each...

The PNW Insect Management Handbook, The PNW Disease Management Handbook, The PNW Weed Management Handbook: These handbooks cover many different crops, but these links will take you to the sections for potatoes.

Pesticide Tables for Potato Pests: These tables are found in the PNW Insect Management Handbook, but this link takes you to a pdf you can download. The tables include insecticide trade names, active ingredients, and information about target pests, insecticide group, REI, PHI, and more. There are tables for single active ingredient products, package mixes, and biological insecticides.

Pesticide Information Center OnLine (PICOL) Database: This is a free, searchable database maintained by personnel at Washington State University. PICOL has current information about pesticide products registered for use in either WA, or OR, or both. Electronic copies of most labels are available from the site.

Cornell University - Organic Production and IPM Guide for Potatoes: This guide is aimed at Northeastern potato growers, so some of the information does not pertain to the Pacific Northwest. We have a much longer, hotter, and drier growing season and a different spectrum of pests in the PNW. Nonetheless, there are some nice tips in the guide. The most recent update was in 2016.

OMRI Products List: This website has a list of products and materials allowed for use in certified organic production.

PESTICIDE DISCLAIMER: Application of a pesticide to a crop or site that is not on the label is a violation of pesticide law and may subject the applicator to civil penalties. In addition, such an application may also resul in illegal residues that could subject the crop to seizure or embargo action. It is your responsibility to check the label before using any product to ensure lawful use, and obtain all necessary permits in advance.
