Powdery mildew – it infects many plants, m.in. peas and cucumbers, on whose leaves and shoots a powdery white coating forms. This leads to an inhibition of growth and a reduction in the yield. Infested plants must be destroyed and harvest residues should be burned.
Downy mildew – attacks peas, spinach, lettuce, cruciferous plants, onion and beetroot. Initially, light green spots with a white coating appear on the lower side of the leaves, which then darkens. Infected leaves wilt and rot, sometimes whole plants die. Please destroy them, burn crop residues.
