Garlic Mustard(Alliaria petiolata), an Invasive species, is an biennial plant native to Eurasia and lives in a variety of environments, from moist and shady forest lower layers to highlands.
This species produces 15,000 seeds per plant, and its high reproductive capacity hinders the growth of native plants and reduces biodiversity. When spreading and establishing, it is difficult to eradicate due to its high seed production and wide ecological habitat range, so efficient management methods are needed based on ecological understanding this species. This study was conducted to evaluate the growth characteristics of Alliaria petiolata under various shading conditions and to develop an efficient control method according to the degree of shading. As a result, after 8 weeks under 75% shading conditions, Alliaria petiolata’s plant height, leaf length, leaf width, and number of leaves grew the most with 85.67cm, 6.79cm, 6.44cm, and 55.25 leaves. After 4 weeks, the leaf area and specific leaf area of Alliaria petiolata also showed the highest values of 47.86 ㎠ and 510.38 ㎠/g. These results show the characteristics of Alliaria petiolata as a shade plant. In order to determine the optimal removal method, mortality rate (%) and number of seeds produced were measured at different root cutting times and depths under no-shading, 35% shading, and 75% shading conditions. As a result, under no shading and 35% shading conditions, when the above- ground part was removed in May and the underground part was cut in April, the mortality rate was 100% and there was no seed production. Under 75% shading conditions, when the underground part was cut in April, the mortality rate was 100% and the number of seeds produced was 0, which was judged to be the most effective control method. The results of this study are expected to contribute to the development of strategies for Alliaria petiolata management, and it is necessary to verify the control effect through future field application.
