During the time period of this report the C. Wayne Ellett Plant and Pest Diagnostic Clinic processed 615 samples for its clientele.  Samples were received from 57 Ohio counties, including both commercial and noncommercial interests. The types of samples processed were categorized as ornamentals and turf (56%), field crops (30%), and fruit, vegetable, and insect identification requests made up the remaining 14%.

(2015-17)  Ornamental Workshop - Nancy Taylor, Francesca Peduto Hand, Plant Pathology

An introductory workshop on ornamental diseases and insects was organized for OSU Extension educators representing 23 different counties in May 2015. It has since been given two more times in 2016 and 2017. This workshop targeted newly hired and seasoned educators who do not necessarily have a background in ornamentals but deal with the commodity as part of their local responsibilities.  The workshop covered basic principles of plant pathology (i.e. pathogen types, symptoms and signs of disease), how to diagnose common diseases of landscape ornamentals, and how to identify common insect pests. Most of the attendants identified themselves as not having a plant pathology or entomology background, therefore this session was well targeted to develop basic skills and competencies.   


2014 - Plant and Pest Diagnostic Clinic - Nancy Taylor, Plant Pathology

Backyard growers, commercial growers, and Ohio residents submit samples to the OSU plant and pest diagnostic clinic to determinetheidentity of insect and disease pests attacking crops, turf, lanscape and nursury plants. In the past year, 828 samples were submitted to the main clinic and 300 specialty crop disease samples were submitted to the Miller lab for diagnosis. Once diagnosed, the clinic sends a report with standard treatment recommendations and factsheets as necessary to help further explain the pest or condition.

During the project period services were utilized in 67 of Ohio's 88 counties. Over 50% of samples were submitted by homeowners (165), Extension educators (100), arborists (160), and landscapers (102) predominantly in the areas of woody ornamentals (416), field crops (148), insect identification (92) and herbaceous ornamentals (82).
