This
handbook is intended as a tool for making decisions regarding the control and
management of important insect pests in the Pacific Northwest. It is written
primarily for growers, County Extension agents, consultants, field and nursery
staff, and chemical industry representatives. Master gardeners and homeowners
may also find the information in this publication useful, though many of the
pesticides listed are available only to licensed applicators. The most
appropriate recommendations for these users are found in the non-commercial or
HOME section of this handbook.
Information in this publication is in a constant state of change. Legal uses
of many pesticides change frequently. These changes include de-listing of crops
or sites from the label, new formulations requiring different application rates,
restrictions on pre-harvest applications, reapplication intervals or reentry
periods or other circumstances.
The information included in the handbook is presented with the understanding
that no discrimination is intended nor is endorsement by the Cooperative
Extension Service implied. Trade names (brand names) of commercial pesticides
are listed in this handbook to help identify pesticide common names. Authors
have assembled the most reliable information available to them at the time of
publication. Criticism of products or equipment not listed is not implied or
intended. Due to constantly changing laws and regulations, neither the authors
nor the Extension Services of Idaho, Oregon and Washington assume any liability
for these recommendations. Any use of a pesticide contrary to instructions on
the printed label is neither legal nor recommended.
We offer our thanks to the over 50 contributors who reviewed the current
management practices for crops in the Pacific Northwest. As in past years, Dr.
Len Coop will post the PNW Insect Management Handbook
on the internet at
http://pnwpest.org/pnw/insects. The web version of the manual includes links to
pest photographs, fact sheets and pesticide labels. Interest in the web version
continues to grow: the 2008 web version of the manual received 101,809 hits, an
increase of nearly 25% over the previous year.
This handbook is revised and reissued annually.
