Abstract

The effect of conidial concentration and length of stigma wetness period on infection of sorghum spikelets by
Claviceps africana was studied in a controlled environment experiment. A spore concentration of at least 106 conidia/mL was required for maximum infection on sorghum panicles. Maximum infection occurred during a stigma wetness period between 4.5 and 6 h. Approximately 11–15% infection occurred when stigmas had been dried immediately after inoculation.
This study demonstrated that the stigma wetness is an important parameter in sorghum ergot epidemiology.
