  1. Choosing a Sample
  2. Submitting a Sample

General Tips for Choosing a Sample

  • Collect a fresh sample: Collect a sample on the day you are submitting it to our office or shipping it to our office. Don't leave samples in vehicles overnight. Intense heat or cold will destroy the sample.
  • Submit samples that are not in transition: Show symptoms of dying. Diagnosis is difficult to impossible with dead or dried plants.
  • Send in a sufficient sample: Whole plants, including roots, are more desirable than individual leaves or branches, whenever possible.
  • Submit a sample of the soil if possible: Keep soil off foliage by wrapping the root ball in plastic, aluminum foil, or submitting in a separate bag from the plant tissue.

Trees and Shrubs

Collect a 12 to 24-inch-long branch with leaves attached. Samples should show transition from healthy to affected foliage.

For Weed/Plant Identification

A single leaf or grass blade is not sufficient. Include as many parts of the plant as possible, including:

  • Flowers
  • Fruits
  • Leaves
  • Plant
  • Roots
  • Twigs

Turf Samples

Dig a 2 to 3-inch-deep, shoebox-sized, rectangular sample (including roots) which shows transition from healthy to affected turf. Wrap the roots with aluminum foil to keep soil intact and prevent contaminating blades.

Insect Identification

Include a dozen bugs, not just one, to ensure a good sample Single specimens are not always complete. Insects are hard to identify when parts are missing. Larvae should be placed in 70 percent rubbing alcohol.
