HOW TO SAMPLE

1. Selecting the Sample

  • Pick both affected and unaffected tissue
  • Preferably, get the margin between the two
  • If plants are small, get some healthy, some declining, and some severely affected
    • It helps to see what the plant is supposed to look like
    • Send entire plant(s) whenever feasible

2. Packing the Sample

  • Wrap foliage in DRY paper towels
  • Wrap the roots in wet paper towels
    • Removing soil from roots can save you money on shipping and may improve sample quality
  • Put in sealed plastic bag
  • Sample submission forms are available online
    1. Fill out basic information (the form is a fillable PDF but handwriting is accepted!
    2. Write story or explain concerns on reverse side
    3. Don’t worry about filling out every section of the form
    4. DO. NOT. PUT. FORM. IN. BAG. WITH. SAMPLE. J Thank you

3. Shipping the sample

  • The NDSU PDL has three addresses!
    1. A walk-in location (206 Waldron Hall, NDSU Campus)
    2. A USPS address that delivers to campus distribution
    3. A shipping address that delivers to the Plant Pathology Departmental Office
  • Contact information 

What to expect

  • Unbiased, professional results
  • Formal report
  • Final diagnoses entered into national database (NPDN National Repository)
  • Turn around varies         
    1. Easy/common samples during slow periods will be > 1 week, or even same day!
    2. Difficult samples during peak times may take up to 2 weeks; turnaround greatly increased by:      
      • Culturing slow growing organisms
      • Abiotic disorders which resemble disease – it takes time to eliminate the likelihood of a disease
      • Unusual samples; we will try to schedule a consultation with specialists who are in and out of the field/office throughout the summer
    3. Never hesitate to contact us for a status update
