Germination of the oospores is stimulated by exudates from roots of a susceptible host nearby. The oospores germinate and [...] or substrate. Oospores are dispersed when soil particles are moved around by humans or machinery. Pythium can survive very well in the soil or substrate

The distinctive feature is the way the lesions look when [...] on the leaves and form a secondary source of infection. They are dispersed by rain, irrigation water or handling of the plants. Infection of the plants [...] both passively and actively. Infection and disease development are favoured by temperatures around 20 °C during the day and cold nights, in combination with

  they are more elongated. The lesions are light brown, sunken and surrounded by a dark brown to red-brown border. The first infection is often on the primary [...] orange-red masses of two-celled conidia are exuded. Secondary infection is by splash dispersal of these conidia. There is no known sexual stage.

• Bacterial wilt, brown rot

  eyes also turn grey-brown. This disease can be distinguished from Clavibacter by the bacterial slime produced from wounds, which is not seen in Clavibacter [...] found soil-inhabitant in tropical and subtropical regions and is transferred by the introduction of propagation materials (seed potatoes, cuttings of ornamentals [...] infected plants to neighbouring plants. The bacteria can also be transported by irrigation water. Disease incidence is highest when soil moisture is high
