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 ...
