  • Please email jennyglass@wsu.edu clear photos of the damaged plant or the insect.
  • For plant problems, images showing the plant in the landscape often provide additional clues as to the cause of the problem.
  • Photos showing the base of the plant at the soil line may also be illuminating when trying to determine root issues.
  • These images should be accompanied by information describing the problem and the plant care (who, what, where, when, why are great questions to explain).

Physical Samples

  • Samples can be mailed to Plant & Insect Diagnotic Lab, WSU Puyallup, 2606 West Pioneer, Puyallup WA 98371 or deposited in or near the cooler/drop box on the south side of Kalkus Hall (three-story brown wood-siding building on upper campus).
