ABSTRACT
Diseases caused by biotic agents Some understanding of the taxonomy of plant pathogenic organisms is required to identify them accurately, understand their biology, and ultimately to best control them. Taxonomy is the science that classifies, categorizes, and names organisms. The taxonomy of plant pathogens, like that of all organisms, continues to change and develop. Ongoing research, discovery of additional species, and modern molecular and biochemical methods allow researchers to more precisely define these classifications, resulting in occasional but significant changes in previous taxonomic schemes.
