Soybean rust, caused by Phakopsora pachyrhizi, is one of the most important constraints to soybean production worldwide. The absence of high levels of host resistance to the pathogen has necessitated the continued search and identification of sources of resistance. In one set of experiments, 178 ...

Fourteen soybean accessions and breeding lines were evaluated for resistance to soybean rust caused by the fungus Phakopsora pachyrhizi. Evaluations were conducted in replicated experiments in growth chambers using detached leaves and under greenhouse and field conditions. In growth-chamber exper...

Despite the advantages of root crops as important staple food crops in the tropics, research and development of such crops has been neglected. There is, therefore, the need for production, processing and utilization techniques to be developed, evaluated and made available to farmers. However, bec...

Cassava anthracnose disease (CAD) caused by the fungus Colletotrichum gloeosporioides f.sp. manihotis has become one of the major economic diseases of cassava in Africa. The expansion of cassava production farmlands particularly in the humid rainfall zones of West and Central Africa has led to an...

Twelve cowpea cultivars were screened for reactions to infection by Colletotrichum lindemuthianum and C. truncatum, causal agents of anthracnose and brown blotch diseases, respectively. Three different inoculation techniques were used: spraying a spore suspension on leaves of seedlings, injecting...
