ABSTRACT
Ageratina adenophora is a noxious plant and it is known to cause acute asthma, diarrhea, depilation, and even death in livestock (Zhu et al., 2007; Wang et al., 2017). A. adenophora grows near roadsides and degraded land worldwide (He et al., 2015b). In the areas where it grows, A. adenophora is an invasive species that inhibits the growth of local plants and causes poisoning in animals that come in contact with it (Nie et al., 2012). In China, these plants can be found in Yunnan, Sichuan, Guizhou, Chongqing, and other southwestern areas (He et al., 2015a) and they have become a dominant species in these local regions. It threatens the native biodiversity and ecosystem in the invaded areas and causes serious economic losses (Wang et al., 2017). It has been reported that A. adenophora can grow in the northeast direction at a speed of 20 km per year in China (Guo et al., 2009). Because of the damage caused by A. adenophora, it ranks among the earliest alien invasive plant species in China (Wang et al., 2017).
