The survival of a pathogen between cropping seasons and its effective dispersal to healthy plants are crucial aspects of the plant disease cycle . If either of these is prevented, the disease will not occur. Most pathogens possess mechanisms to survive intercrop periods or periods of unfavourable environmental conditions. The spread of inoculum can be airborne, soil borne, water borne, seed or clone borne, or vector borne. Airborne inoculum can travel for great distances, even across oceans, while soil-borne inoculum is rarely spread any great distance. Many pathogens are dispersed by more than one mechanism. These fungi are able to form resting structures that enable them to survive long periods without a suitable host or when environmental conditions are unfavourable.
