Sample Submission

Bipolaris1.2.jpgA submission is composed of symptomatic and asymptomatic plugs taken from the same area; homeowners wanting to submit a residential sample are urged to contact their local cooperative extension office prior to submission.

Each sample MUST be accompanied with a sample submission form found by clicking HERE.  Please take time to fill out the form as completely as possible.  Our diagnosis is only as good as the evidence that we receive.

Steps to be used for sending a sample

  1. Samples should be turf plugs (removed using a cup-cutter device or similar tool) cut from the edge of the area where there is active disease (ex. from the edge of a patch).  The plug should encompass approximately half diseased and half healthy tissue.  Alternatively, one diseased and one healthy plug could be cut from one problem area.
  2. Soil-laden ends of the plugs should be wrapped in aluminum foil.  Samples could be placed in a plastic bag, but DO NOT seal the bag completely.
  3. Wrapped samples should be placed in a box with padding tightly surrounding the samples (newspaper or leftover bubble wrap work well).
  4. The box should be firmly sealed after placing the completed sample submission form in the box.
  5. The package should be sent using expedited mailing such as FedEx, UPS, or similar.  Hand-delivering the samples directly to the laboratory is also an option.  The quicker we get the sample, the faster we can diagnose the problem.
