I provide extension entomology programming for fruits. University fruit research and extension programs across the Southeast are heavily regionalized. I am active in this scientist- and grower-led initiative, having provided leadership in our multi-state effort since its inception.

Georgia is third nationally in blueberries, while Georgia and South Carolina are third and second in peach production. Uncompromising market demand for almost blemish-free fruit is confounded by inadequate sampling technologies and our poor understanding of pest biology. These conflicting realities mandate conservative, pesticide-intensive IPM programs. That said, growers want dependable, cost-effective IPM programs that help them meet escalating societal standards for food safety, worker safety and environmental stewardship.

Peaches are my main focus. In addition to my extension responsibilities, I participate in collaborative peach research efforts. I also serve as South Carolina's fruit entomologist and as an adjunct professor at Clemson University. Current research focuses on the peachtree/lesser peachtree borer complex, and scale. UGA's Pesticide Safety Education Program (PSEP) is responsible for the critical training, and on-going re-certification training of some 25,000 Georgias currently licensed to apply restricted-use pesticides.
