PPCDL Workshops

The PPCDL Workshops will be held during the month of March 2027 and are available to NPDN members, partners, and colleagues.

Registration for the 2027 PPCDL Workshops will open on November 03, 2026, and close on November 17, 2026. As they become available, find details about our new registration process and a link to the registration form in the Registration section below.

The workshops are supported by the USDA and the Plant Protection Act 7721 funding, meaning diagnosticians can request a scholarship to cover travel expenses.

The PPCDL Workshops are hosted by the scientists of the Plant Pathogen Confirmatory Diagnostics Laboratory (PPCDL) in Laurel, Maryland. The instructors and workshop planning team have developed a schedule offering a wide variety of topics and both in-person and virtual delivery options.

Course Descriptions and Agendas

Workshop offerings may vary from year to year based on needs. All workshop titles and descriptions are available in the PPCDL Workshop Catalog.

Registration

This will be a particularly special year for the PPCDL Workshops, as we celebrate 25 years of offering workshops, with the first held in 2003.

The link for the registration form will be posted here when registration opens on November 03, 2026.

Registration requests will be submitted as an application this year, using the PPCDL Workshop-Registration Request Form.

If your laboratory has more than one person planning to request registration for a PPCDL Workshop, you must designate a registration request submitter. The Registration Request Form will allow the submitter to enter the registration requests of all your lab members. This new feature will help workshop coordinators follow your laboratory’s goals and selections for training through the receipt of one overall laboratory plan.

Consider attending the webinar…helpful for completing the PPCDL Registration Request Form! New this year, PPCDL and NIS staff will be available to provide an overview of the PPCDL and MFIT workshops’ content and answer your questions. The webinar recording will be posted here for those who cannot attend.

When is registration open?

Registration for the 2027 PPCDL Workshops will open on November 03, 2026 and close on November 17, 2026.

What happens after your registration request is submitted?

Registration Request Forms will be reviewed after the close of the registration period on November 17th.

The coordinators hope to begin inviting applicants in early December and complete the registration process before the holiday break so participants can start making their travel plans.

Applicants are given 3 days to respond to the workshop invitation. If no response is received, the coordinators will assume the applicant is no longer interested and invite the next person on the list.

Travel and reimbursement information

PLANNING

The start of travel planning begins with the receipt of the Letter A. After all workshop participants confirm their workshop invitation, the group will receive the Letter A. DO NOT make travel arrangements until you receive the Letter A. Letter A is the signal telling you it is OK to begin your travel planning.

Important note: DO NOT PLAN to leave before the completion of the workshop. If you attend an in-person workshop and hope to return home on the final day, do not book a return flight before 8:00pm. You will need at least 3 hours to comfortably get to the airport. The area and its airports are busy around the clock, so plan for lengthy ground travel times and long lines at check-in and getting through security. We encourage participants to leave the following morning.

REIMBURSEMENTS

NEW for 2027: Receipts will be required for all expenses except mileage and per diem for meals.

Cornell University will reimburse your home institution. Participants must follow their home institution’s travel procedures and policies. PLEASE SUBMIT YOUR REIMBURSEMENT TO YOUR INSTITUTION FIRST. When a participant submits their travel expense letter to the Cornell coordinators and their institution’s representatives at the same time, corrections often follow. Institution reviewers may find issues with the participant’s travel materials and require an adjustment. Frequently, this modification forces a re-submission on Cornell’s side. It is best to have your travel reimbursement letter completely reviewed by your institution first, then submit it to Cornell.

Workshop Policies and Guidelines

The PPCDL Workshop Guidelines were created to provide helpful information and tips for those planning to attend an PPCDL Workshop. The guide provides workshop procedures and guidelines pertaining to registration, how to receive specific workshop details, how to make travel arrangements and how to request travel expense reimbursement. The guide includes the answers to the most frequently asked questions and common occurrences from past workshop seasons.

Each workshop participant should understand their institution’s rules pertaining to travel arrangements and reimbursements. The workshop coordinators cannot override institution rules.

The workshop coordinators hope the information supplied in this document, coupled with the understanding of each participant’s institution procedures, will result in a stress-free planning and reimbursement process. Please read the entire document!

Workshop Policies

The Workshop Policies document covers both the MFIT and PPCDL Workshops. The policy document provides key rules and guidelines and covers the expectations related to workshop registration, attendance, requirements, and travel expense reimbursement.
