oliveknot-pathogens2J.M. Young | View Article
Olive knot, caused by a pathogen or pathogens within the group of bacterial pathogens currently known as Pseudomonas savastonoi, is described. The ecology, transmission and methods of control of the pathogens are discussed. Strategies to minimise the effects of infection are recommended and these depend on attention to specific details in programs for pruning, irrigation and use of fertilizer. Introduction of the pathogens into previously olive knot-free countries is most likely to occur through the importation of infected nursery stock.
