Soil-borne diseases of cotton and peanut:

Assisting cotton breeders (both public and private) in breeding for disease resistance to root-knot nematodes, bacterial blight, and Verticillium wilt.  The breeding work emphasizes both greenhouse and field evaluations.

Chemical testing (both experimental and labeled materials) for Thielaviopsis basicola, root-knot and reniform nematodes.  Testing program is conducted both in greenhouse, and small and large plot field trials.

Management of pod rot of peanuts, in particular when Pythium spp. are present.  This work involves both sampling methodology and testing threshold based methods versus traditional, calendar based timings.

Interaction between irrigation rates and plant pathogens in large-scale agricultural settings.  This work is done with root-knot nematode and Verticillium dahliae, on cotton.
