Lack of herbicides for Scutellaria baicalensis, one of the most important medicinal herbs in traditional Korean medicine, has led to a poor weed control in S. baicalensis cultivation. A greenhouse experiment was conducted to select safe pre-emergence (PRE) and post-emergence (POST) herbicides for S. baicalensis. Of the 6 PRE herbicides tested, pendimethalin only showed an acceptable damage on pre-emergent S. baicalensis even at double the rate of its recommended dose, and alachlor, napropamide, and pendimethalin showed very low damage on post-emergent S. baicalensis. Scutellaria baicalensis was significantly damaged by all the tested POST herbicides at its 5 to 6 leaf stage. Of them, acetolactate synthase inhibitors such as nicosulfuron and thifensulfuron showed relatively low damage, 6% and 15% at double the rates of their recommended doses, respectively, when applied at the 11 to 12 leaf stage of S. baicalensis. Therefore, these results demonstrate that pendimethalin as a PRE herbicide and thifensulfuron and nicosulfuron as a POST herbicide can be sequentially used for weed control in S. baicalensis cultivation.
