Pathogenic variability of Xanthomonas manihotis, the causal agent of cassava bacterial blight

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 programing the planting of cassava according to climatological factors such as rainfall.
