It is important to bear in mind that pesticide recommendations for one state, region, or country may not be legal in another. Further, University recommendations are often outdated even before they are printed due to limited resources. Always follow current label directions when using pesticides.
The PNW Insect Management Handbook presents current/recent recommended management practices for most insects of potatoes and other commercial vegetables in the Pacific Northwest. Similar recommendations are available from various sources in other potato-producing regions (Maine Pest Management Guide, Pest Management Handbook (Clemson University); Potato Production in Alberta, etc.).
Proper rotations, field selection, and choice of variety can minimize problems with insects.
The following sites, among many others, provide general recommendations for identifying and controlling potato insects.
As noted above, potato insect control recommendations for the U.S. Pacific Northwest are available in the PNW Insect Management Handbook. Additional information on safety and proper pesticide use are are also provided. Control recommendations are for information only. OSU does not guarantee success and can not accept responsibility for consequences of use.
