Soilborne plant diseases
Expertise and Instrumentation: Ecology and control of soilborne pathogens of cotton, rice and soybeans 

I conduct research on the ecology of soilborne plant pathogens and their control through chemical, cultural and alternative strategies. The research is directed toward developing sustainable cropping systems for cotton and other field crops.

Current research activities include Thielaviopsis basicola, the cause of black root rot, and the synergistic interaction between T. basicola and nematode. Research is characterizing Rhizoctonia solani populations, anastomosis groups, in soils under different cropping systems in Arkansas. The importance of Pythium root rot in losses associated with temporary flooding for soybean and cool soil temperatures for rice is being investigated in cooperation with other plant pathologists. Decision-aids for the application of in-furrow fungicides for the control of cotton seedling diseases are being developed.
