This project did an evaluation of the cross pathogenicity and virulence of both Exserohilun turcicum and Ranumlispora soighi Macrophominaphaseolina collected from diverse hosts in Southern African (Botswana) to determine if host preference and other differences of isolates can be detected and analyzed in pure culture tests. Deploy TAES nurseries and other sorghum to SADCC/ICRISAT for use at several SADCC locations to evaluate resistance to specific pathogens and to characterize pathogen populations. Diseases for specific evaluation include leafblight, sorghum downy mildew, unknown viruses, sooty stripe, gray leaf spot, and anthracnose. Develop improved inoculation and field screening techniques for sooty stripe and other diseases in the SADCC region.
