Abstract
Ergot (sugary disease), caused by several species of Claviceps including C. africana, is a serious panicle disease in most of the sorghum (Sorghum hicolor) producing countries of the wor ld (Bandyopadhyay et al . 1998). Ai rborne secondary conidia are the pr imary source of inoculum of C. africana (Bandyopadhyay et al . 1998) and are responsible for the rapid spread of the pathogen (Frederickson et al. 1989,1991,1993). Secondary conidia are produced on sterigmata f rom germinated macroconidia f rom the honeydew. To date, al l infect ion studies have been conducted wi t h mixed suspensions of macroconidia and secondary conidia, sprayed onto stigmas. However , in nature this does not occur, as the secondary conidia are not deposi ted in a suspension on the st igmas, except when car r ied there by raindrops (Tonapi et al . 2002). In this article, we describe techniques to produce and harvest secondary conidia. and to inoculate st igmas; these techniques mimi c natural infect ion.
