the host. Zoospores are spores with flagellae, which enable them to move through water. Infection is usually from the root to the foot, but direct infection [...] sporangia, a type of spores) with sporangia are formed, that protrude through the stomata. Secondary infection is either by germinating sporangia or by [...] Dispersal in the soil happens via water, since the zoospores can readily move through water. This explains why the disease spreads more rapidly when the water
