2009 International Berry Health Benefits Symposium

Berry Health Benefits Symposium Join scientists from around the world for an international conference to showcase the latest research regarding the relationship berries have with a variety of health benefits. Attendees will have the opportunity to discuss new research findings and learn about the profound positive effects of berries on human disease prevention.

The two-day event took place on June 22 & 23, 2009 at the Portola Hotel & Spa in Monterey, California. 

New online tool for growers:, an online trade magazine for northwest berry growers, is now officially launched! This has been made possible through the support of the Washington Red Raspberry commission with grant money provided by a Washington State Specialty Crop Grant.
The purpose of this site is to:

  • Connect growers with the people and companies that can help them evaluate the risk and cost of implementing new types of equipment and technologies onto their farms.
  • Accelerate the implementation of effective, cost efficient labor saving practices.
  • Moderate accurate, timely information exchange between growers and their supporting industry suppliers, their public researchers and their processors.

Tissue analysis & soil testing

Post harvest is the best time to do most soil and leaf testing for nutrient management planning.

  • Blueberries: Tissue testing and pH monitoring are most critical. Complete soil tests don't correlate as well with plant needs as tissue tests. Click Here to view OSU's Blueberry Nutrient (and testing) Guidelines.
  • Caneberries: While annual soil testing has been the industry norm, Oregon State's recently updated nutritional guide recommends annual leaf testing with soil tests done just every few years. Click Here to view OSU's Caneberry Nutrient (and testing) Guidelines.

Northwest Integrated Pest Management

This Site has been created by Peerbolt Crop Management (Tom & Anna Peerbolt) to provide the northwest small fruit industry with a convenient place to access needed information on integrated pest management (IPM). It will also serve as an informational base for industry resources and events. The flexibility of being web based allo1ws us to provide timely weather and pest alerts as well as update the constantly changing control options available to growers. The advantage (and disadvantage) of this project is that it relies on interaction and a flow of information to keep it alive and working. Please, let us know if there are links that don't work or if there is information we should update or add that you'd find useful.

Our Sources

Much of our chemical pest control label information comes from Joe DeFrancesco, a pesticide specialist at Oregon State University. Joe runs the IR-4 project there as well as coordinating Pest Management Strategic Plans for many Oregon crops. He also provides growers with much needed information on the ever changing control options. His activities on behalf of the northwest small fruit industry are critical as a link between regulatory agencies, control manufacturers and growers.

Our insect and disease information relies on many sources besides our own knowledge and experience. The primary ones are the Caneberry PMSP, Blueberry PMSP, Strawberry Crop Profile, Oregon State University Online Plant Disease Manual and PNW Insect Control Manual. Thanks to Jay Pschiedt and Joe DeFrancesco for doing such a great job. Other major sources are:Whatcom County Raspberry IPM Manual, Washington State University, Hortsense, the B.C. Ministry of Agriculture, University of California IPM Manual, and Cornell University. Other sources throughout the U.S. are also sited and linked.


We have cited the photographer or source of all the photos on this site, noting the few unknown to us. Many of the pictures on this site are our own or come from Oregon State University. However, to provide photos that best help identify a pest or diagnose a problem, we have depended on many sources. If you have photos that you would be willing to share, please let us know.

Promise and Disclaimer

We will keep the information accurate and up-to-date to the best of our abilities. However, we can't issue any guarantees on this information since we are relying on many sources and changes can happen quickly. If you're in doubt, check with your local sources of information--extension, other growers, industry fieldmen, or private consultants.


Any photos by T. Peerbolt or A. Peerbolt can be copied and used as long as we are cited as the source. If you feel that we have used your information or photos inappropriately, please contact us.
