Sorghum ergot - a sticky disease problem in southern AfricaD EFredericksonauthorErgot disease of sorghum is not new to Africa - the causal pathogen, Claviceps africana Frederickson, Mantle, and de Milliano was first recorded in Kenya as far back as 1923. However, ergot disease only began to gain recognition as a potential problem in sorghum production in the 1960s, when all the A-lines in Nigeria's national breeding program became infected, to the near complete exclusion of seed production (Futrell and Webster 1965).Sorghum2000International Crops Research Institute for the Semi-Arid TropicsArticle
