Plant Disease Diagnostic Testing

The Plant Disease Diagnostic Lab now has three options for diagnosing plant diseases. The traditional way to test is by submitting plant material to the lab that can be triaged and cultured in the lab to identify if a disease is present. The next option is to purchase the Plant Disease Identification Box and culture the plant material yourself. The Plant Disease Identification Box is designed for those with limited plant material or for plant material that is prohibited by federal law regulations to be received by the lab. The lab’s newest option is the Digital Plant Disease Diagnostic Submission Form which accepts samples of plants with symptoms of disease or possible disease (with illustrative photos), digitally, at a cost of $8 per submission.

Currently no physical cannabis samples can be received by the lab unless it is considered hemp, and an accompanied hemp license number is provided on the submission form. The Plant Disease Diagnostic Lab does not provide virus or viroid testing on cannabis.
