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 ...

The predominant farming system in La Colorada (Magdalena, Colombia), where cassava is a subsistence crop, is briefly reviewed. The intensive land use has caused soil leaching and infestation with root pathogens such as Diplodia manihotis and Fusarium oxysporum and cassava production has decreased...
