This paper reviews the research progress made in pathology within the bean research network in Africa over the period 1985-92. Attention is drawn selectively to the most pertinent advances in preference to a fully comprehensive description of all work conducted in the region. A discussion of dise...

Some methodologies, including examples, for developing bean var. specifically adapted to intercropping with maize are considered. Since every breeding program has to contend with genotype x environment interactions, decisions have to be made regarding the locations for breeding nurseries, the con...

The hypothesis that HCN in cassava is a defence mechanism against arthropod pests is suggestive, but quality and quantity of empirical data is unsatisfactory and scarce. The burrowing bug (Cyrtomenus bergi Froeschner: Cydnidae: Hemiptera) is recorded as a major pest on cassava in the neo-tropics ...

Bean Stem Maggot (BSM) is a serious production problem in many African countries. In South Africa, the problem receives very little research and extension attention. This study set out to assess the magnitude of the BSM problem at Greytown during the 1995 season. Using a split-plot trial, split f...
