Abstract

Common groundsel (Senecio vulgaris L.) is winter annual weed and become problematic in winter crop field such as onion and garlic. The weed can produce more than 10,000 seeds and the seeds can be easily spread by wind. Senecio vulgaris distributes worldwide except tropical area and nationwide in Korea. The seeds can germinate wide range of temperature and have irregular dormancy affected by temperature, light intensity, and burial depth. The germination characteristics can make S. vulgaris germinable through the year except summer. Senecio vulgaris is known as autogamy but interspecific cross is possible. Photosystem II inhibiting herbicides such as linuron and protox inhibiting herbicides such as oxyfluorfen are very effective for management of S. vulgaris. Biological control of S. vulgaris using fungus had been tried but not been succeed. Proliferation of winter annual weeds like S. vulgaris resulting from increase of winter mean temperature by climate change could be expected.
