Protect cucumber plants against powdery mildew

Greenhouse cucumbers are usually only attacked by powdery mildew, as the fungus is also comfortable in dry and warm weather. The outbreak of disease, which can be recognized by white flour-like spots, can usually be prevented with a few tips. This includes that the plants must not stand too closely so that the air can circulate better. Furthermore, the greenhouse should be ventilated regularly. In any case, the lowest possible humidity must always be ensured. In contrast to the greenhouse cucumber, the free-range cucumber is almost exclusively attacked by downy mildew. Wet years in particular cause considerable damage to cucumbers, caused by downy mildew. You can recognize the pathogen by initially yellowish spots that are sharply demarcated by the leaf veins. In the later course of the disease, the leaves die off quickly and after a while there is no living part left of the plant. As a preventive measure, an airy and sunny location should therefore be chosen, as this dries the plant quickly and the dangerous fungal spores of downy mildew cannot germinate. Whether greenhouse cucumber or outdoor cucumber: When buying young plants, look out for resistant plants or seeds. Resistant varieties are for example: Amber, Bella, Charlotte, Hayat and Schubert.
