Frequently asked questions
Question: My plant is dying. What should I bring in for testing?
A: A whole plant is always ideal for testing. If a large tree or shrub, a handful of fine feeder roots is sufficient along with branches. A branch with both symptomatic and healthy tissue is required for accurate analysis. Completely dead plants are useless for analysis.
Question: Can you test for herbicides?
Answer: No. The plant pest diagnostic lab cannot test for herbicide residue. We can only rule out plant pathogens or insects pests as causes of disease. Please visit the Tennessee Department of Agriculture (TDA) website to file a pesticide complaint.
Question: Can you tell me if there is a disease in my soil?
Answer: No. We currently require root tissue to confirm the presence of disease causing soil borne pathogens.
