These categories are specific for Nursery grown plants. This would include field or container grown plants.

A completed Plant Diagnostic Request Form is required for all submissions.

Always use these general guidelines for submitting a greenhouse sample.

  • Samples should be fresh.

  • Samples should represent the early to middle stages of the problem.  A completely dead and decaying sample cannot be reliably diagnosed.

  • Samples should be carefully packaged and shipped early in the week to avoid weekend layovers during which the sample will deteriorate.

  • Be sure to include sample documentation and background information on the Plant Diagnostic Request Form.

  • Pictures of the problem in the field are always helpful.  The environmental conditions of the plant can play an important role in the diagnosis.
