Abstract
The infectivity of C. africana on pearl millet (Pennisetum glaucum) lines in Africa was studied. C. africana consistently gave 100% disease incidence on male-sterile sorghum in experiments undertaken in Zimbabwe. C. fusiformis established disease with moderate incidence on most but not all lines tested. In contrast, C. africana established a parasitic association with all the pearl millet lines tested, with incidence as high as 23% in ICMSR 260, the genotype that also supported the highest incidence with C. fusiformis. However, the disease severities were always low, between 1 and 5%. All infections on pearl millet were verified as the sphacelial stage by virtue of their conidial characteristics. After 1 passage through a pearl millet host, C. africana did not apparently become more infectious on this host.
