Abstract
Viruses are known to infect all living organisms on earth. Hence, the possibility of employing the viruses, as biocontrol agents against fungal and bacterial pathogens infecting plants, has been examined. The phenomenon of hypovirulence due to viral infection of fungal pathogens like Cryphonectria parasitica has been exploited for the control of the destructive chestnut blight disease. Infection of many fungal pathogens by mycoviruses has opened up a new vista for the suppression of some of the diseases infecting economically important crops. Likewise, several bacterial pathogens are infected by specific bacteriophages. The effectiveness of phage therapy against bacterial pathogens infecting grapevine, tomato, pepper, apple, potato, cotton and rice has indicated that this approach may become a feasible disease management strategy in future. The practical utility of the phenomenon of cross-protection for the management of Citrus tristeza virus and Papaya ringspot virus infecting citrus and papaya respectively has been well demonstrated as examples for viruses as biocontrol agents.
