Leaf curl — Kale
Brassica oleracea L. (Curly kale Group)
In kale, the term is not a standalone disease but describes morphological changes caused by abiotic stress, pests, or viral infection.
In the reference 8 varieties crop Curly kale, where this is mentioned in the description.
Deformation and curling of kale leaves are most often a physiological response to environmental stress, such as sharp temperature fluctuations, 'cold shock' during seedling transplanting, or moisture deficiency. Pest feeding, particularly by cabbage aphids, also causes damage, resulting in deformation and yellowing of leaf blades.
A specific pathogen that causes leaf curl symptoms is the Cabbage leaf curl virus from the Geminiviridae family. The vector for this virus is the whitefly. External signs include yellowing, vein clearing, pronounced crinkling, and leaf curling, with the disease being most common in regions with warm climates where virus vectors are active.
