To explore the role of protective enzymes in cassava (Manihot esculenta Crantz) resistance to mites, transgenic cassava lines overproducing copper/zinc superoxide dismutase (MeCu/ZnSOD) and catalase (MeCAT1) were used to evaluate and molecularly confirm cassava resistance to Tetranychus cinnabarinus. Laboratory evaluation demonstrated that, compared with the control cultivar TMS60444 (wild type...
Africa produces over half of global cassava; however, the continent's average yield is below potential yields achieved under experimental conditions. Many factors contributing to low include lack quality varieties, poor soils, limited access capital, competition for labor, as well pests and diseases. Plant diseases are major biotic constraints cassava production have caused considerable food in...
Cassava mosaic disease (CMD) is the most widespread and economically important disease of cassava (Manihot esculenta Crantz) in tropical Africa.

Forty five households in four cassava production zones were interviewed in relation to their cultural practices and crop residue management...
In this study, we used a household level survey to assess choices of varieties and demand for improved cassava varieties.
