Aflatoxin contamination resulting from maize infection by Aspergillus flavus is both an economic and a public health concern. Therefore, strategies for controlling aflatoxin contamination in maize are being investigated. The abilities of eleven naturally occurring atoxigenic isolates in Nigeria t...

Ability of five strains of Trichoderma pseudokoningii (antagonists) to sup-press radial growth of Fusarium verticillioides (Sacc.) Nirenberg (=Fusarium moniliformeSheldon) was examined in vitro. These were T. pseudokoningiistrain1 (IMI 380933), strain2 (IMI 380937), strain3 (IMI 3809 39), strain4...

Twenty graminaceous plant species were evaluated for their susceptibility to the two sorghum ergot pathogens Claviceps sorghi and Claviceps africana. Five speciesviz.,Sorghum arundinaceum, Sorghum halepense, Sorghum versicolor, Sorghum virgatum and Pennisetumglaucum were found to become infected...

Soybean rust, caused by Phakopsora pachyrhizi Syd., is a major disease limiting soybean [Glycine max (L.) Merr.] production in many areas of the world. Yield losses of up to 80% have been reported in experimental plots in Taiwan. Although the disease is not always yield limiting, it has the poten...

Aspergillus flavus has two morphotypes, the S strain and the L strain, that differ in aflatoxin-producing ability and other characteristics. Fungal communities on maize dominated by the S strain of A. flavus have repeatedly been associated with acute aflatoxin poisonings in Kenya, where managemen...
