David N. Appel

Dr. Appel is a Professor Emeritus in the Department of Plant Pathology and Microbiology (PLPM) at Texas A&M University. Since coming to Texas A&M in 1981, his research program focused on the epidemiology, diagnosis, and control of forest and shade trees, with an emphasis on the devastating oak wilt epidemic in central Texas. Dr. Appel also studied the biology and control of winegrape diseases, and was involved with statewide surveys for sudden oak death and citrus greening. He taught graduate and undergraduate courses on introductory plant pathology, plant disease diagnosis, forest protection, and environmental regulations, and served in a variety of administrative posts during his tenure at TAMU. Dr. Appel received various awards from his department and professional societies for his accomplishments, but is most proud of the impact his work had on the treatment and survival of oaks and grapevines in Central Texas.
