Dianthus caryophyllus

Diseases & pests on this plant

• carnation Fusarium wiltFusarium oxysporum f.sp. dianthi

  One-sided yellowing and wilting: shoots on one side of the plant go pale grey-green then straw-coloured while the other side stays green; stems show a brown streak in the vascular tissue when split lengthwise; the whole plant slowly collapses and dies. Symptoms worsen in warm soil.

• carnation rustUromyces dianthi

  Powdery, chocolate-brown pustules erupt on leaves, stems and calyces, often in rings; the leaf surface over each pustule first blisters then splits to release the rusty spores; heavily rusted leaves curl, dry and die; stems can be girdled and snap.

• grey mould (Botrytis)Botrytis cinerea

  Fuzzy grey mould on leaves and stems.

• two-spotted spider miteTetranychus urticae

  Yellow stippling on upper leaf surface, fine webbing.
