Alpha-terthienyl as active compound
Original Abstract
Intercropping marigolds with tomatoes in organic systems reduced root-knot nematode (Meloidogyne incognita) populations by 67%. Alpha-terthienyl from marigold root exudates was the primary nematicidal compound. Tomato yields improved 18% compared to monoculture controls.
