Nigeria, the world’s largest producer of cassava, harvests 54 million metric tonnes (Mt) of cassava tubers annually. More than 95 per cent of its uses require peeling which generates up to 14 Mt of waste annually; mostly due to challenges related to drying. Sun drying is practically impossible du...

Metabolites of toxigenic fungi and bacteria occur as natural contaminants (e.g. mycotoxins) in feedstuffs making them unsafe to animals. The multi-toxin profiles in 58 commercial poultry feed samples collected from 19 districts in 17 states of Nigeria were determined by LC/ESI–MS/MS with a single...

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...

Grain mold caused by a complex of fungi is an economically important disease of sorghum worldwide. Little is known about the epidemiology of sorghum grain mold, which is essential for its management. Studies were conducted to quantify the effects of wetness duration on grain mold development unde...

Fungal communities in soils of Nigerian maize fields were examined to determine distributions ofaflatoxin-producing fungi and to identify endemic atoxigenic strains of potential value as biologicalcontrol agents for limiting aflatoxin contamination in West African crops. Over 1000 isolates belong...

Soybean rust, caused by Phakopsora pachyrhizi, is an important disease in Nigeria and many other soybean-producing countries world-wide. To determine the geographical distribution of soybean rust in Nigeria, soybean fields were surveyed in the Derived Savanna (...
Several maize near-isogenic inbred lines were subjected to comparative proteomics to identify kernel proteins associated with resistance. These lines were developed in Nigeria through a joint project between ARS-SRRC and the International Institute of Tropical Agriculture. The goal of this projec...
