Crops

For all crops looking to send samples to the K-State Diagnostics Lab.

Sample Submission – High-quality samples lead to high-quality diagnoses

  • Collect and ship samples on or before Wednesday to avoid weekend storage.
    • Collect healthy and symptomatic plants (labeled).
    • Collect the entire plant.
      • Dig up the plant to keep the root system intact.
      • Bag roots separately to avoid soil contact with leaves.
      • Place bagged roots and above-ground materials in a larger plastic bag.
      • Label and use plastic bags instead of paper; do NOT add water. This maintains sample integrity.

Once collected:

  • Fill out the submission form with as much information as possible. Include variety/hybrid info (especially for wheat). Attach it to the outside of the sample bag.
  • Bring all to the Extension office on Monday or Tuesday by 9 am, so we can ship plants ASAP overnight via UPS or FedEx.
