The main pathological problems of the cassava crop are summarized. Four bacterial diseases have been identified and their causal agents characterized: CBB, angular leaf spot, bacterial stem rot, and bacterial stem gall. Two mycoplasmal problems, witches` broom and antholysis, have been identified...

Greenhouse studies on pathogenic variability of Xanthomonas manihotis did not reveal the occurrence of distinct pathogenic races. The non-race status of the pathogen suggests that CBB could be well-controlled in the field by using known levels of genotype resistance in specific ecosystems and by ...
