Alan

I joined the Entomology and Plant Pathology Department in April 1985. I received my Ph.D. at North Carolina State University under the supervision of Dr. Leon Lucas in the Department of Plant Pathology, where I studied the biology of Rhizoctonia zeae. Since joining UT Extension with a 100% Extension appointment, I have provided leadership for educational programs in plant diseases affecting turf, ornamental plants, forages, Christmas trees and forests. This includes assisting Extension agents with their educational programs, as well as implementing a state-wide educational program in plant pathology.

Research focus

I am a member of the UTIA Dogwood Team that developed the Appalachian series of flowering dogwoods resistant to dogwood anthracnose or powdery mildew. I have worked with the Thousand Canker Disease of Walnut team and the forest health management team. I am currently part of the Combating Rose Rosette team which is funded by a USDA Specialty Crops Research Initiative grant.

Extension and outreach focus

The Green Industry (nursery, greenhouse, turf, sod) is second only to grain crops as the top ‘crop’ commodity in Tennessee. It was valued at over $315 million in 2011. In 2013, Tennessee’s turfgrass industry contributed $5.8 billion to the state’s economy and created close to 67,000 full and part-time jobs. Limiting the growth of this industry are horticultural pests which include insects, diseases and weeds. My emphasis in the last three years has been to support county Extension agents in their work with plant diseases affecting horticultural crops, also producers and managers in the Green Industry. First detector and master gardener training has also been a primary focus.

I have reached my target audiences by mass media, social media, group meetings, email, phone calls, field visits and office visits. Funding for these programs have come from Extension funds, fee based programs, USDA grants, and Southern Region IPM grants. I have supported the work of the Soil, Plant and Pest Center by assisting with plant disease diagnoses in the lab and via Distance Diagnostics.
