Marigold Root Extract Latin Name: Tagetes erecta L. Description: Marigold is a half-hardy sub-shrub native to Mexico and Central America. It is eaten as an herb and is commonly used as a substitute for tarragon. The leaves have a tarragon-like flavor, with hints of anise. Common names include Mexican marigold, peric?n, Mexican mint marigold, Mexican tarragon, Spanish tarragon, and Texas tarragon. Marigold grows 18-30 in (46-76 cm) tall. The plant is bushy with many smooth, upright, unbranched stems. The leaves are linear to oblong, about 3 in (7.6 cm) long, and shiny medium green, not blue-green as in French tarragon (Artemisia dracunculus var. sativa). In late summer it bears clusters of small yellow flower heads on the ends of the stems. The flower heads are about 0.5 in (1.3 cm) across and have 3-5 golden-yellow ray florets. The flowers are hermaphroditic (have both male and female organs) and are pollinated by insects. Part of Plant Used: Root. Active Ingredient: Alpha-terthienyl. CAS No.: 1081-34-1 Molecular Formula: C12H8S3 Molecular Weight: 248.39 Function: Marigold Root Extract is used as insecticides, fungicides, and nematocides. T. minuta has insecticidal componentsin its leaves, owers, and roots. Marigold roots contain the light-sensitive compound alpha terthienyl, which can suppress nematode populations and improve the growth of plants like tobacco and tomatoes. A phototoxin extracted from marigolds, alpha-terthienyl, was shown to be extremely insecticidal against mosquitoes, but did not affect nontarget organisms like the ostracod, caddisßy, and Physa sp.
