W4008 Committee Updates

“Integrated Onion Pest and Disease Management”

Multistate Research Project
October 1, 2022 to September 30, 2027

Next meeting: January 5th, 2023, in Denver CO.


Registration for the W-4008 annual meeting on January 5, 2023 is now open.

The meeting will be held at the Savannah International Trade and Convention Center, 1 International Dr, Savannah, GA 31401.

We are combining our W-4008 and Stop the Rot registrations for your convenience, since there is a lot of overlap between the participants for the two meetings.

  • Please register for one or both meetings here
  • We kindly request that you register for W-4008 and Stop the Rot meetings as soon as possible, but preferably no later than Friday December 2, 2022, so that we can provide attendance estimates for catering purposes.
  • Please note that while there is no registration fee for the W-4008 and Stop the Rot meetings, you MUST also be registered for the Southeast Regional Fruit and Vegetable Conference, which is required to access the venue and get lunches. Register and pay at https://seregionalconference.org/, where you will also find travel information and access to conference hotel rates. Early bird registration ends on December 13.
  • The W-4008 and Stop the Rot meetings will be in-person only. No virtual access will be provided. We will follow COVID protocols in place at the meeting venue at the time and will keep participants updated as needed.

About W4008

The W4008 project has built on the success of previous multi-state projects (W1008, W2008, W3008), broadening the scope to include new studies for solving the US onion industry’s most important problems by:

  • Evaluating onion germplasm for resistance to pathogens and insects.
  • Investigating the biology, ecology, and management of onion thrips and other pests.
  • Investigating the biology, epidemiology, and management of onion plant pathogens.
  • Facilitating discussions between W3008 participants and onion industry stakeholders that will advance onion pest and disease management.

Multistate Research

Multistate research allows State Agricultural Experiment Stations (SAES) to interdependently collaborate in projects that two or more states share as a priority, but for which no one state could address singularly. Learn more about multistate research projects here
