Root Rot
MajorDisease
Fine roots rot brown to blackish brown, growth stops and the lower leaves yellow. The plant wilts easily in the daytime and eventually dies outright.
Cabbage White Caterpillar

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.
