overview

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.
