Pests and diseases (6)
Problems recorded for this plant, most serious first.
Cabbage White Caterpillar
MajorPest
Irregular holes appear in the leaves and eventually only the veins remain. Dark green pellets of frass are conspicuous at the crown and on leaf undersides.
Aphids
CommonPest
Small green or black insects cluster on shoot tips and leaf undersides, crinkling the leaves and stopping growth. The honeydew they excrete supports sooty mold that blackens the foliage.
Diamondback Moth
CommonPest
Larvae graze the leaf tissue from below, leaving the upper skin as white window-like patches. As they grow they chew many small holes and also attack the growing point.
Cabbage Armyworm
CommonPest
Young larvae feed in groups on the leaf underside, eating only the tissue so the leaf turns translucent white. Larger larvae chew big holes and can strip a plant bare in a single night.
Bacterial Soft Rot
OccasionalDisease
The crown or the head becomes water-soaked and soft, then collapses into a slimy mush. The rotting tissue gives off a distinctive foul odor.
Clubroot
OccasionalDisease
Leaves wilt during the day and recover morning and evening, and growth is markedly poor. Pull the plant and the roots carry many spindle-shaped or irregular galls.
