Extension Interests and Current Efforts
My Extension and research program is focused on those diseases and plant parasitic nematodes that affect peanuts (Arachis hypogaea), cotton (Gossypium hirsutum), soybeans (Glycine max) and corn (Zea mays). My Extension efforts are devoted to providing timely, research-based recommendations to growers, University of Georgia Cooperative Extension agents, and consultants for the management of all diseases and plant parasitic nematodes that affect the crops listed above in Georgia and the southeastern United States. This information is disseminated to our clients through presentations at producer meetings, Extension bulletins, newsletters, and the Internet. Working with other researchers and Extension specialists at the University of Georgia and colleagues from the agrichemical industry, I have coordinated investigation, development, and implementation of “Peanut Rx,” a risk index program for the management of tomato spotted wilt, leaf spot diseases, southern stem rot, and Rhizoctonia limb rot affecting peanut. In addition to disease and nematode management recommendations, my program is deeply involved in the national “Soybean Rust IPM-pipe” sentinel plot monitoring program and the “Southern Corn Rust IPM-pipe” sentinel plot monitoring program (www.ipmpipe.org/).
In addition to Extension activities, a significant portion of my program is devoted to applied research on pathogens of peanut (primarily Cercospora arachidicola, Cercosporidium personatum, Scelrotium rolfsii, Cylindrocladium parsiticum, and Meloidogyne arenaria), fungal diseases of corn (especially Puccinia polysora and Exserohilum turcicum), southern root-knot nematode (Meloidogyne incognita) affecting cotton, soybeans, and corm, and Aspergillus flavus as it affects corn and peanuts. Research programs include efforts in the laboratory, the greenhouse, and the field.
Finally, I am very interested in international collaboration efforts. I am currently involved in the Peanut Collaborative Research and Support Program (Peanut CRSP) that is funded by the United States Agency for International Development. I have worked with indigenous peanut farmers in Guyana, South America, since 2002 and with peasant farmers in Haiti since 2007. I am also actively involved in the Philippine Phytopathological Society.
