Allium schoenoprasum

Diseases & pests on this plant

• leek rustPuccinia porri

  Bright orange, slightly raised, powdery pustules break out along the leaves of leek (and other alliums); in heavy attacks the leaves yellow and die back from the tips, reducing yield and quality. The vivid orange streaks rubbing off as powder are unmistakable.

• onion / garlic white rotSclerotium cepivorum

  Patches of stunted yellowing plants in row, white fluffy mycelium on basal plate + roots, tiny black poppy-seed sized sclerotia in white growth, complete bulb decay with foul smell.

• bacterial soft rotPectobacterium carotovorum

  Water-soaked dark patches on bulbs/heads/tubers that quickly turn slimy + foul-smelling, complete liquefaction of internal tissue, characteristic strong fishy/sulphur odour from rotting tissue, infections spread rapidly in storage if not separated, conditions of warmth + moisture accelerate rot to whole-bin loss within days.

• grey mould (Botrytis)Botrytis cinerea

  Fuzzy grey mould on leaves and stems.
