Those spots then turn into dark brown angular lesions [...] of leaves, Alternaria solani can spread to the flowers (especially dangerous in crops for seed production) and to the crown. Sporulation of Alternaria occurs [...] A. brassicae and A. brassicicola : adjust the sowing date to avoid conditions conducive to infection. In greenhouses: avoid high RH. Prevent plant diseases

Later infections cause the berries to split and one or both parts to possibly shrivel. Life cycle and appearance of Downy mildew [...] mildew Pathogens causing downy mildew are not fungi but Oomycetes and related to Pythium and Phytophthora . They survive as oospores. From these oospores or

it is tuber-borne. Spread from plant to plant results from bacteria moving from the roots of infected plants to neighbouring plants. The bacteria can [...] conditions are more favourable. This makes it more difficult to recognize infected fields. How to prevent Bacterial wilt, brown rot Use disease free propagation [...] help the bacteria to infect the crop Do not use cut potatoes for propagation, since cutting tubers can increase disease incidence with up to 250% Quarantine

Phytophthora blight

Zoospores are spores with flagellae which enable them to move through water. Infection is usually from the root to the foot, but direct infection of the foot also [...] wetness is required. Dispersal is by wind and rain causes the pathogen to be returned to the soil from infected plants. Dispersal in the soil happens via water [...] Phytophthora blight Phytophthora species are very destructive organisms belonging to the Oomycetes and are therefore strictly speaking not fungi. They thrive at

Angular leaf spot

The distinctive feature is [...] bacterial exudate forms on the underside of the leaf. This exudate changes to a white film when it dries. Lesions may merge as they grow and later also [...] types of vascular tissue of the crown can be infected, creating a look similar to that of a Phytophthora fragariae infection.
