The main habitat of Solanum carolinense, an ecosystem-disrupting invasive plant in Korea, is known as pasture. However, it is now occurring not only in pastures, but also in roadsides, embankments, paddy and upland levees and coastal sand dunes. The flowers of S. carolinense bloom purple flowers similar to eggplant flowers from June to July, and bear rounded yellow fruits around September. S. carolinense propagates by seeds and underground rhizomes. Roots cut by tillage can be regenerated with 0.5 cm fragments. Therefore, indiscriminate tillage can cause the spread of S. carolinense, but a method of consuming and removing nutrients from rhizomes through periodic tillage (at least 3 times at 30-day intervals) can be considered. It can also be controlled by spraying herbicides such as dicamba, triclopyr-TEA, or glyphosate. On the one hand, the systematic control of S. carolinense requires additional research on cultural and biological control techniques.
