Nursery and Christmas Tree

What is the Grower Assisted Inspection Program (GAIP)?

Nurseries involved in GAIP use best management practices (BMPs) to prevent the introduction of Phytophthoras.

What are best management practices (BMPs)?

BMPs focus on the overall cultural care of the nursery in order to monitor all aspects of their facilities for pest prevention.

What are the requirements?

Each nursery must identify five mandated critical control points (CCPs) and create a management plan for each CCP, including the following:

  • Plant procurement
  • Water management
  • Potting media
  • Native soil
  • Used containers
  • Optional additional pathways as identified by the nursery

How were the five mandated CCPs chosen?

CCPs are based on research through Oregon State University (OSU) and the Oregon Department of Agriculture (ODA). Using the best available science, CCPs may be modified to reflect the most current information.

How do I know if I have correctly identified the CCPs?

The auditor or ODA staff member will conduct a walk through to help identify potential areas.

Is training required?

At least one member of the nursery must take and pass the OSU Phytophthora online course: Training for nursery growers.

Is documentation required?

Records must be maintained in a nursery mitigation manual for a minimum of two years. This information is reviewed during annual audits.

How are records maintained?

A nursery may use a variety of documentation for their audits, such as

  • Paper documentation
  • Computer records
  • Interviews
  • Lab test results
  • Visual inspections

Is assistance available to help create the mitigation manual?

A template and an example of a completed manual are available for use.

Is there a fee to be a member of the GAIP?

There is no fee, however there may be costs associated with BMPs the nursery chooses to implement.

Other tips

  • Create a flow chart or document each step of the nursery daily practices for each department. This information can help identify areas that need improvement, help plan a better work flow, and lead to better communication between departments.
  • Have periodic meetings between departments to discuss any changes or problems.
  • Train staff members to recognize problems and let them know the correct person to notify.
  • Post information about pests in a visible place, such as as the lunchroom, so that employees can look at material on their own.
  • Have employees attend training seminars.​
