Apple scab season
As any plant pathologist will tell you, three fundamental factors must coincide for disease to appear and spread successfully. The disease causing agent, for example, spores of the apple scab fungus, Venturia inaequalis, must occur at the same time as the susceptible host organism, for example, leaf tissue of ‘Bramleys Seedling’ apple trees, and in the correct environmental conditions for infection. In our apple scab example, this means long enough periods of leaf wetness and warmth for fungal spores to land, germinate and infect.
