Leading Nematologist Bob Riggs Retires

Bob Riggs

University Professor Robert “Bob” Riggs concluded a distinguished career of 48 years at the University of Arkansas when he moved to the emeritus ranks on June 30.

A native of Pocahontas, he received B.S.A. and M.S. degrees from the University of Arkansas and a Ph.D. in plant pathology with an emphasis in nematology from North Carolina State University in 1958. He joined the UA Department of Plant Pathology as an assistant professor in 1958.

Riggs became the principal expert on race and host characterization and management of soybean cyst nematode (SCN) and identified SCN as a major pest of soybeans in Arkansas and other southern states. He was involved in the initial characterization of the first four races of SCN and has since characterized all races. He collaborated with Dr. C. E. Caviness and other UA soybean breeders on development and release of soybean cultivars that are resistant to SCN.

Riggs is often cited for developing a crop rotation system that alternates resistant and susceptible soybean varieties with a non-host crop to manage SCN infestation. His applied research on how management practices and environmental conditions affect SCN populations have been the basis for widely used management practices. He also conducted basic research in DNA analysis of SCN species.

Riggs discovered a fungus in soils from soybean fields in Arkansas that reduces nematode populations to low levels. He and his graduate students conducted extensive research on the potential for using the fungus as a biological control agent against SCN.
