Tagetes minuta L. is native to the temperate grasslands and relatively high-altitude areas of South America. In 1990, it was first discovered in the Beijing Botanical Garden in China. In 1994, Pema Dawa introduced the species as a Tibetan medicine from the mountains of northern India to his courtyard in Gangjiang Village, Wolong Town, Milin County. Around 2010, scholars discovered that Tagetes minuta L. was widely invasive, which aroused extensive social concern. Featuring small weight, large number, and awns, Tagetes minuta L., is easy to spread and has a high seed germination rate, with 20% of the reproductive investment. The plant is tolerant of barrenness and drought and adapts to climates with large diurnal temperature differences and strong light conditions. Rich in aromatic substances and essential oils, the leaves and flowers serve medicinal, food, flavoring, health care and cosmetic purposes. Thiophene in the roots and bioactive components in the essential oil have anti-inflammatory, sterilizing, insect-repellent, and fly control effects, with significant allelopathy on native species. The biological and ecological characteristics of Tagetes minuta L. lay the material basis for its population spread. According to Tibetan folklore, we suggest using physical methods or biological control techniques for ecological control and strengthening the research of development and application to guide its economic benefits in Tibetan Buddhist supplies.
