Microorganisms as biocontrol agents against bacterial citrus diseases

Citrus represents one of the most widely grown crops on planet, extensively cultivated for both fresh fruit and juice markets. The productivity citrus orchards can be seriously affected by highly aggressive pathogenic bacteria, such as Xanthomonas citri subsp. citri, Xylella fastidiosa pauca currently Candidatus Liberibacter asiaticus. Different microbiological biocontrol agents have been described against these pathogens, antagonistic bacteria (mainly species from Pseudomonas Bacillus genus) bacteriophages. This review summarizes all control strategies reported so far bacterial diseases that affect citrus, highlighting those fields study where there is great potential yet to discovered.
