Sorghum ergot, initially restricted to Asia and Africa, was recently found in the Americas and Australia. Three species causing the disease have been reported: Claviceps sorghi in India, C. sorghicola in Japan, and C. africana in all ergot-positive countries. The objective of our study was to stu...

The introduction of photoperiod-insensitive, short-and medium-duration, high-yielding rainy season (kharif) sorghum (Sorghum bicolor (L.) Moench) hybrids in India more than 20 years ago has led to dramatic increases in grain yield (from 587 kg ha -1 in 1970 to 1407 kg ha -1 in 1996). This was acc...

Sorghum (Sorghum bicolor(L.) Moench) is the fifth important cereal crop after wheat (Triticum aestivumL.), maize (Zea maysL.), rice (Oryza sativaL.), and barley (Hordeum vulgareL.) in the world. It is cultivated in about 46 million ha with a total production of 62 million t (FAO 1998). Asia and A...

Aflatoxins are a common contaminant of cereals that can cause cancer, liver disease, immune suppression, retarded growth and development, and death, depending on the level and duration of exposure. Maize is an introduced crop to Africa and there have been efforts over the last 20 years or so to r...

A regional Sorghum Head-Bug and Grain Mold Trial was conducted in 1996 and 1997 by WCASRN in, respectively, 15 and 13 research stations in ten west and central African countries. Empirical relationships between weather factors and head-bug damage on the one hand, and between weather factors and g...

Resistance to anthracnose, caused by Colletotrichum graminicola, in sorghum was identified through field screening at two locations (Samanko and Longorola) in Mali. The occurrence and progress of anthracnose were monitored on 19 sorghum lines plus resistant and susceptible checks in the 1996 to 1...
