Research:
Areas
of Research Interest and Expertise:
Diseases
of cereal crops caused by fungi, bacteria, and viruses. Research is
primarily with fungal diseases of maize and sorghum.
Areas
of Research:
Major
diseases (pathogens) occurring on sorghum and maize. These include:
charcoal rot (Macrophomina
phaseolina), sorghum downy mildew (Peronosclerospora sorghi),
head smut (Sporisorium
reilianum), aflatoxin (Aspergillus flavus), several foliar
diseases, sorghum ergot (Claviceps africana) and grain mold (Fusarium moniliforme
and F.
thapsina).
Research
areas for pathogens include ecology, survival, initial inoculum,
pathogen variability, and host:parasite interaction (especially under
stress environments). Part of a large interdisciplinary sorghum
improvement team at Texas A&M that is active globally through
INTSORMIL research activities.
