Fees for Services Per Sample
All samples have a "Basic Sample Fee" unless otherwise stated. The fees were updated in 2025. The basic fee covers our standard diagnostic and identification procedures for plant diseases, plant problems and insect identification. Includes initial sample evaluation, microscopic examination, routine cultures for fungal and bacterial pathogens and management suggestions, if needed. Also includes examination of images submitted as samples for identification of plant diseases and disorders and pests affecting the sample. If multiple sample types are sent in to the clinic each sample will be given a separate sample number.
