Field Diagnosis of Key Diseases & Insect Pests in Vegetables

This course will take place at the Madren Conference Center and Clemson University Organic Farm Clemson, SC, September 11, 2014, 9am – 4:30pm.

This one-day course will focus on field diagnosis of key diseases and insect pests affecting vegetable crops in South Carolina and the region. Participants will learn about techniques for sampling and identification of key diseases and their symptoms, and for insect pests and their natural enemies. Participants will gain experience with field monitoring of disease and insect pests on vegetables at the Clemson Organic Farm, and with instruction will practice disease and insect identification using stereo microscopes and hand lenses. All participants will receive a hand lens to take home. Lunch will be provided, and there will be ample time for questions and discussion about disease and insect problems and solutions.


Dr. Anthony Keinath, Professor of Plant Pathology, Clemson University.  Dr. Keinath serves as the vegetable pathologist for South Carolina. He serves as chair of the Publications Board for the American Phyopathological Society, and he has served as Editor-in-Chief of Plant Disease, the leading international journal for applied plant pathology research.  His research focuses on management, ecology, and epidemiology of fungal and bacterial pathogens of cucurbits and cole crops and general integrated pest management for vegetables. His area of expertise is the fungus Didymella bryoniae, the cause of gummy stem blight and black rot on cucurbits.

Dr. C. Powell Smith, Professor of Entomology and Extension Vegetable Specialist, Clemson University. Dr. Smith is based in Lexington County and serves as our state vegetable IPM specialist and is a regional lead Extension agent for vegetable and small fruit crops.
