Bacterial Soft Rot
Erwinia carotovora subspecies carotovora, atroseptica and chrysanthemi
Soft rot occurs on all crucifer crops, but it is particularly damaging to Chinese cabbage and common cabbage. Infected plant tissues first develop a water-soaked lesion that enlarges rapidly in diameter and depth. The affected area becomes soft and mushy and generally turns a dark color in advanced stages of disease development. Soft rot-infected cruciferous plants almost always give off an offensive odor, perhaps in part due to invasion by secondary organism. Disease losses from soft rot may occur in the field, transit, or atorage.
